How to initiate a payment ?
One of our customers makes a transaction on an e-commerce website or wants to initiate a transfer.
Through this API “Payment initiation” available for Crédit Coopératif customers, you can submit a real time payment initiation request.
The connected customer will be requested by his bank to validate this transaction :
- He identifies and authenticates himself
- Then, he selects his bank account with a sufficient balance for the transaction amount
- Finally, the bank seals the transaction after the client has strongly authenticated himself to validate the transaction (some exemptions of this authentication process exist)
In addition, this version brings a single SCA flow if the debtor IBAN is forwarded in the PIS request :
- PSU verifies the displayed transaction information
- Finally, the bank seals the transaction after the client has strongly authenticated himself to validate the transaction (some exemptions of this authentication process exist)
You can only use this API if you are a Payment Initiation Service Provider (“PISP”), this prerequisite is described in “Eligibility” use case.
Once this prerequisite has been fulfilled, the global process will be the following one :
01- As a PISP provider, you can propose funds transfer services to customers, or allow them to pay their purchases on an e-merchant web site you have contractualized with. Thru your interfaces, the customer selects in which bank (ASPSP) his account(s) is/are domiciliated and you collect the transaction information (purchase amount, IBAN creditor, …).
02- During the first exchange with ASPSP’s infrastructures, you will have to request an authorization token. As PISP, you have to get this token BEFORE you can use ressources of the API. This token is generated by the ASPSP AFTER you authenticate as a PISP service provider using your eIDAS certificates.
As banking account holder (ASPSP), we will verify if your certificates and national agreements are valid.
For this step, it is not necessary that we identify and authenticate the customer before generating the access token.
03- If all above checks are correct, you will be able as PISP to get the OAUTH2 access token thru a secure exchange with BPCE API platform (see “Retrieve your access token” use case).
04- By presenting this access token valid only for this transaction, you can then use ressources of the “payment initiation” API in order to :
- Initiate a payment/transfer (see “Send a payment initiation request” use case) ;
- Retrieve the status of a payment/transfer initiation request (see “Retrieve the status of a payment initiation request“) ;
- Confirm a payment/transfer initiation request or a payment/transfer cancellation request(see “Confirm a payment initiation request”)
Consume the API
Prerequites
As TPP you have to be accredited by a national competent authority for this Payment Initiation Service Provider (“PISP”) role.
To access payment initiation API methods, you have to get an OAUTH2 access token provided by customer’s banking institution, obtained with your credentials.
You and the customer’s banking institution have successfully processed a mutual check and authentication (exchange of eIDAS QWAC certificates).
Then, you present your OAUTH2 access token to consume the payment initiation API’s methods.
Initiate a payment
Two use cases exist for a payment initiation :
1) The PISP forwards a payment request on behalf of a merchant : the customer (PSU) purchases goods or services on an e-commerce website (see top of the diagram below).
There is a contract between the merchant and the PISP.
The merchant forwards the requested payment characteristics to the PISP and redirects the customer to the PISP portal.
The PISP asks the customer in which banking institution (ASPSP) is located his account. Then he prepares the payment initiation request and sends this request to customer’s bank.
The beneficiary, as being the merchant, is set at the payment level.
2) The PISP forwards a transfer request on behalf of the owner of the account. The customer provides the PISP with all information requied for the transfer.
The PISP asks the customer in which banking institution (ASPSP) is located his account. Then he prepares the transfer request and sends this request to customer’s bank.
As a PISP, you forward to the ASPSP the request for payment initiation via the POST /paymentRequests method (see “Send a single payment request initiation” use case).
The authentication method supported by the ASPSP is the REDIRECT approach :
1) The customer is redirected to identification screen proposed by his banking institution and he will enter his online banking identifier
If the PISP provides client’s online banking identifier directly in this request, this step will be skipped.
2) The customer is redirected to an authentication screen proposed by his banking institution in order to validate its identity
3) The customer is redirected to account selection screen proposed by his banking
If there is only one eligible IBAN, or if the PISP has already collected customer’s account to be debited and include it in the request, it will be automatically selected and displayed.
4) The customer selects (if applicable) and validates his account to be debited
5) The customer is redirected to a strong customer authentication (SCA) screen proposed by his banking institution to validate is payment/transfer
The process for this step depends on SCA method provided to the PSU by his bank institution (OTP SMS, secur’pass, etc.).
It also depends on PSU’s device (PC, mobile, smartphone, tablet).
6) The customer is redirected to a payment request confirmation screen proposed by his banking institution
7) The customer accepts or declines the transaction and is redirected to PISP app using call back URLs
In order to do so, the payment initiation request posted by the PISP includes one or two call back URLs :
The first one will be called by the customer’s banking institution if the payment request is processed without any error or rejection by the PSU (the PSU has given his consent for the payment)
The second one is to be used by the customer’s banking institution in case of processing error or rejection by the PSU (refusal of consent). This second URL is optional : the first url will be used if the second one is not transmitted
8) the TPP has to forwed a last confirmation request using POST /payment-requests/{paymentRequestResourceId}/o-confirmation for executing the PIS operation.
In addition, this version brings a single SCA flow if the debtor IBAN is forwarded in the PIS request :
1) The customer is redirected to a payment request confirmation screen proposed by his banking institution
2) The customer accepts or declines the transaction
3) The customer is redirected to an identification screen proposed by his banking institution in order to validate its identity
4) The customer is redirected to PISP app using call back URLs
5) the TPP has to forwed a last confirmation request using POST /payment-requests/{paymentRequestResourceId}/o-confirmation for executing the PIS operation
Retrieve the status of a payment of a payment request initiation
You may recover ay anytime the status of an initiation of payment via the method GET / paymentRequest(see “Recover the status of a payment request initiation” use case).
This call allows you to retrieve all the payment initiation data enriched with the resource identifiers and the status of the payment initiation request and the payment it contains.
The data is available for 35 days.
Cancellation of a payment/transfer request
You may cancel an initiation of payment via the method PUT /paymentRequests(see “Cancel a payment request initiation“) effective as soon as it has been processed.
The SCA is performed using REDIRECT mode.
Confirmation of a payment request (PISP)
You may confirm a payment initiation request or payment initiation cancellation via the method POST /paymentRequests/{paymentRequestResourceId}/o-confirmation(see “Confirm a payment initiation” use case).
There is no confirmation for a PIS cancellation.
Get your token
Principle
Access to PSD2 API features is granted by the bank with an authorization token (or access token) issued using OAUTH2 standardized process.
How it works
See also STET / Part I
1- The customer (PSU) provides the identity of the bank which holds his accounts (ASPSP) to the TPP.
2- The TPP initiates an OAUTH2 access token request sequence by redirecting the customer to the ASPSP’s authorization infrastructure using GET /authorize
3- ASPSP will :
-
- Identify and authenticate the PSU
-
- Check your role and validity of your eIDAS certificates and agreement
4- Once checks are done and correct, ASPS will redirect the PSU to your site using “call-back” URL given in the GET /authorize and to ASPSP for the Go Live process.
You will find in the response of this request a one-time-token with a short life period.
5- You can then call the ASPSP in order to request the OAUTH2 token (and refresh one) using POST /token with previously received data (incl’d the one-time-token).
Note : these /token requests for getting the Authorization Code flow shall be sent WITHOUT the « scope » parameter.
6- ASPSP will :
-
- Check your role and validity of your eIDAS certificates and agreement
-
- Checks the direct or indirect matching between the Authorization Number within the eIDAS certificate and the [client_id] value
7- Once checks are done and correct, ASPSP returns a response HTTP200 (OK) with data including the access token.
8- As soon as you get the OAUTH2 access token (and a 180-day valid refresh token) issued by the bank, you can use it for each API request within the “Authorization” header, prefixed by the token type “Bearer”.
The [client_id] that is linked to the access token must directly or indirectly match with the Authorisation Number that is located within the TPP’s eIDAS certificate (QWAC).
If the access token is expired, the request will be rejected with HTTP401 with an error equal to “invalid_token”.
The request can be replayed once the access token has been refreshed suing the use case “Refresh your token“.
If your refresh token is about to expire, you will have to perform again all this process, meaning also redirect to ASPSP for customer’s strong autentication (PSU SCA).
For more details, see also OAUTH 2.0 Authorization Framework : https://tools.ietf.org/html/rfc6749#section-4.1
Example
You can find an example of this request in section “Test our API” and then “Sandbox“.
How to use the fallback mode
Principle
In order to comply with PSD2 regulations, banks available on this BPCE API developer portal have setup contingency measures in case of unplanned unavailability of the dedicated API interface.
The principle of this « fallback » solution is explained below:
This fallback mechanism meets PSD2 regulatory requirements (article 33/RTS). It can be used with the same conditions and prerequisites applicable for the dedicated API interface which are specified in the “Eligibility” use case.
Roadmap
Please do find below our estimated roadmap :
| Features | Sandbox Deployment
BPCE API Dev Portal & Sandbox |
Live Deployment
BPCE Live API Gateway |
| Fallback (*) | Not applicable | Septembre 2019 |
(*) Main features :
- Use the same API dedicated interface endpoint. The list of our banking institutions and the possible values of <bkcode> are specified in the “Limitations” use case ;
- A parameter (header ‘fallback:1’ present or absent) managed directly by the TPP allows do differentiate any « Fallback » request from dedicated interface PSD2 API requests ;
- Use of same TPP eIDAS certificate (QWAC) to be presented for mutual TLS authentication ;
- Use the same PSU authentication procedure and means for accessing online banking services ;
- This fallback solution is always active, even so the dedicated interface API must be used systematically in first priority. Its usage is subject to strict conditions as described in Article 33 of RTS, and can’t be used as the main access for PSD2 features. It will be monitored as such and every abuse will be automatically reported to our national competent authority.
Example
- If PSD2 API are not available due to unplanned unavailability or systems breakdown (see RTS Art. 33), TPP should use the following request with <codetab>=17515 as an example :
POST https://www.17515.live.api.89c3.com/stet/psd2/oauth/token
with :
- its live eIDAS QWAC certificate
- fallback:”1″ parameter in the header
2. If all checks are successful, the TPP will receive in the header of the response with url online (allowing to access banking login web page) as well as the JWT token.
3. TPP can then apply its proprietary login process using PSU credentials.
For more details about POST request, see STET V1.4.0.47 / Part I / section 3.4.3.2 / page 22 or STET V1.4.2.17 / Part I / section 3.4.3
Note
Please note the following constraints which apply on this fallback mechanism :
- No re-use of the API dedicated interface context, neither any of 180-day validity access token generated for AISP role
- Only online internet banking features are used as a reference (excl’d mobile banking features) and are accessible thru the fallback mode. As an example, online banking doesn’t propose any e-commerce transactions to customers, so PISP could NOT propose this feature in fallback mode
- The user of payment services (PSU) must be connected to the TPP PSP app, so no AISP batch process is possible
- PSD2 also imposes a reinforcement of strong customer authentication (SCA) for accessing direct online banking services. Therefore fallback mechanism leverages on reinforced PSU online banking authentication procedures and means such as (non exhaustive list) :
- Soft token
- OTP SMS
- Physical token (corporate market)
Sandbox assembly
Introduction : detailed features of the Sandbox
You can use the BPCE API sandbox:
- Via the BPCE portal Try-It (see « Try-It console » use case) ;
- Directly through your application by calling the payment initiation API of the BPCE-API platform (sandbox assembly).
In sandbox assembly, there are two types of requests:
- A first request to retrieve the authorization token (see “Retrieve your access token“) ;
- A second one to send a request to the payment initiation API (see “Send a single payment initiation request” and “Retrieve the statuts of a payment request initiation“).
Your application must request the AS (authentication server) to get an access token via its authentication key.
This access token will enable your application to submit the POST /payment-requests and the GET /payment-requests methods of the payment Initiation API.
You can perform a series of requests :
- Submit POST /payment-requests method to initiate a payment
- Then, submit GET /payment-requests/{paymentRequestResourceId} with the parameter paymentRequestResourceId got in response of the first request, to get the payment status
The data used in the tests are based on persona (see “Test data” use case). This will enable you to choose specific profiles according to the tests.
The list of current available bank institutions for sandbox assembly for this API is detailed below (“bkcode” parameter used in URLs) :
| Bank code | Bank name | Bank short name |
| 13807 | B.P Grand Ouest | BPGO |
| 13807 | CMM Grand Ouest | CMMGO |
| 17515 | Caisse d’Epargne Ile De France | CEIDF |
| 12579 | Banque BCP | BBCP |
Sequence stets to test access to the PISP API from your APP
Prerequisites
You must declare your APP on BPCE API portal (see “My apps” menu) and send us your QWAC and QSEALC test certificates public keys so we can :
- Declare your APP as a consumer application of the API ;
- Integrate your QWAC and QSEALC test certificates public keys in our infrastructure ;
- Retrieve and control your organizationId and your “PISP” role in our TPP registry.
Please note that as a TPP, you must be accredited (or in the on-going accreditation process) by any european competent authority (ACPR in France) for this Payment Initiation Service Provider role (“PISP”).
STEP #1 : Retrieve your access token

successfulReportUrl => recovered from the body given as input
unsuccessfulReportUrl => recovered from the body given as input
iban => recovered from the body given as input
creditorName => recovered from the body given as input
X-Request-ID => transmitted as input
STEP #3: Nominal sequence of PSU identification & SCA
Sequence of identification and strong authentication screens:
Using the URI returned in consentApproval, it is possible to play the sequence of screens.
1) The PSU is redirected to an identification screen presented by his ASPSP (redirection mode) in which he will enter his remote banking identifier.
Warning : only one call to this screen can be made
=> the “nonce” parameter in the URL that gives access to this screen can only be used once (any second call with this nonce will rejected)
=> if necessary, a new call to PaymentRequests is required to get a new token
The remote banking identifier of the customer is to be entered (see “Test data” use case for the data sets of the banking institution), example for the persona “Marc” of the Banques Populaires :
Note: If the PISP provides the remote banking identifier of the customer in its request (field “debtor/privateId/identification“), the following step is directly triggered.
For Caisses d’Epargne, if the customer is a professional or a corporate, he will have to enter is user number in addition to his remote banking identifier.
2) The customer is redirected to a first authentication screen proposed by its ASPSP in order to validate his/her identity:
The SMS code for authentication is to be entered (see “Test data” use case for the data sets of the banking institution), example for the persona “Marc” of the Banques Populaires:
This sequence depends on the strong authentication method proposed to the customer by the bank (SMS OTP, soft token, etc…).
It also depends on the equipment connected to the PISP APP used by the customer (PC or mobile / smartphone / tablet).
3) The customer is redirected to a screen where he will have to select its account to be debited.
Example for the persona “Marc” of the Banques Populaires who has 4 accounts, three of which are eligible for DSP2 payment initiations (see “Test data” use case for the datasets of the banking institution):
IMPORTANT NOTE : If the PISP provides the IBAN of the customer to be debited in its request (field “debtorAccount“), only the corresponding account will be selectable and proposed to the customer : example below for the persona Tech’n Co of the Banques Populaires.
Note: If the customer does not have an account, the request for payment initiation will not succeed and the customer will be redirected to your APP. Example for the persona “Thomas” of the Banques Populaires.
4) The customer selects and validates the account to be debited :
5) The customer is redirected to a second strong authentication screen proposed by his banking institution to validate his payment (dynamic linking).
Screens are identical to the strong authentication screen of step 2) to validate the customer’s identity.
The final decision whether or not to apply an authentication exemption is still at the discretion of the ASPSP as described in article 2 of the RTS of the DSP2. So far, exemptions are not possible for the SCA step to validate the payments.
6) The PSU is redirected to a confirmation screen of the transaction proposed by its ASPSP.
Note: when the customer does not validate the payment initiation (or in the event of a timeout on the account selection page for example) the customer is redirected to the next page :
The customer is redirected to the PISP APP which provides in its first initiation request one or two call back URLs:
The first (successfulReportUrl) will be called by the banking institution in case the payment initiation request is processed and if the customer has given its consent for the payment.
A “code” parameter is added to this successfulReportUrl which is mandated to request the access token for the /o-confirmation method :
Example : https://<votre SuccessfulReportUrl>?code=GbmTn1ZZ76bibgvCRLxD4lNp8wMzkd
The second one (unsuccessfulReportUrl) will be used by the bank in case of refusal of consent or if the validation kinematics of the payment initiation is interrupted at one of its stages (example: timeout on the identification screen, on the account selection screen to be debited or the strong authentication screens). This second URL is optional : the first URL call back (successfulReportUrl) will be used if the second is not filled.
Sequence of the identification and strong authentication screens when the remote bank identifier of the customer (*) is transmitted in the request:
When the access identifier for the remote bank for the customer (debtor/privateId/identification field in the payment initiation request) is filled in, the call to the identification screen of the customer is not performed, cf. drawing below :
(*) for Caisses d’Epargne, Banque BCP, Crédit Coopératif et BTP Banque PSU segments PRO & ENT : we require having the PSU subscription number separated fomr the usage number by a “-“.
STEP #4 : Retrieve the Status of a payment initiation request (only available in live production)
This method get /payment-requests/{paymentRequestResourceId} allows you to retrieve all the payment initiation data enriched with the resource identifiers and the status of the payment initiation it contains.
The description of this feature and fields of the request is described in the use case “Retrieve the status of a payment request initiation“. The data is accessible for 35 days.

Headers :
X-Request-ID : MyXrequestId123
Status code : 200 OK
Notes on parameters :
resourceId => equals to paymentRequestResourceId
paymentInformationStatus => gives payment initiation status
transactionStatus => gives transaction status
X-Request-ID => transmitted as input
STEP #5 : Confirm payment initiation status (only available in live production, NOT in sandbox)
This mandated method POST /payment-requests/{paymentRequestResourceId}/o-confirmationallow to confirm a payment status for security reasons.
Please note that the method POST /payment-requests/{paymentRequestResourceId}/confirmation is not implemented.
The TPP needs to request a specific access token :

Version history
STET specifications
This REST-based API is compliant with the STET standard developed by the french market initiative (https://www.stet.eu/en/psd2/) in order to comply with PSD2 regulatory requirements. It takes into account functional limitations specific to Crédit Coopératif savings banks network.
As a reminder :
- payment services directive (PSD2, (UE) 2015/2366 of 25/11/2015) went into force on january 13, 2018 : http://eur-lex.europa.eu/legal-content/FR/TXT/?uri=CELEX:32015L2366
- it is supplemented by regulatory technical standards for strong customer authentication (RTS, Commission Delegated Regulation (EU) No 2018/389) and common and secure open standards of communication that will apply on september14, 2019. These standards are called RTS (Rules Technical Standards) : https://eur-lex.europa.eu/legal-content/FR/TXT/?toc=OJ%3AL%3A2018%3A069%3ATOC&uri=uriserv%3AOJ.L_.2018.069.01.0023.01.FRA
In France, the ordinance n° 2017-1252 of August 9, 2017 implements the PSD2 directive into the regulatory section of the monetary and financial code. This ordinance has been supplemented by two decrees (n° 2017-1313 and n° 2017-1314 on August 31, 2017), and five orders that were published on August 31, 2017
| Our API version | STET standard version |
| v1 | v1.4.0.47 |
| v1.4.2 | V1.4.2.17 |
You can consult the virtual assistant on this portal.
Description of TPP support
According to Article 30 (5) of the RTS, a support for third-party providers is available. This support can be joined via the form on this BPCE API portal (https://www.api.89c3.com/en/contact-us). Responses are sent during office opening hours (09:00 – 18:00 Central European local Time) even so a 24h/7d monitoring process of our IT systems exists.
Its general principle is shown below, taking into account delays of Article 30 (4) of the RTS :

Deprecation process
According to API product life cycle, an API version can be deprecated (means this API is not any more accessible on gateways and sandbox). An overlap period between two major API releases is provided as described below :
The communication on the deprecation of a version N will be done at the release date of version N+1 through this portal / “roadmap” section.
Planning
This API can evolve. Please note that API modifications can occur out of the three-month regulatory notice period (art. 30 des RTS / paragraphe 4). We apply this in case of :
- urgent functional issue to solve impacting all PSU of at least one major customers segment
- security issue
- evolutions requested by the national competent authority
