Change/note

25 Jul 2023

Following the EBA amendments under Commission Delegated Regulation (EU) 2022/2360, this dedicated interface enables the SCA consent exemption under SCA-RTS, Article 10a for AISPs. This feature allows AISPs to extend the timeline for the renewal of SCA from every 90 days to every 180 days. To avail of the 180 days SCA consent exemption on the AIS flow, the newly created consents should contain the date value of up to 180 days in future for the validUntil parameter. In case you need any assistance on the above please contact us at: compliance@saltedge.com

Registration

The process of TPP registration is made via an API request to TPP Register endpoint. In order to access Provider Sandbox you need to use eIDAS QSEAL test certificate.

Access to production environment is allowed only with production QSEAL certificates. It is possible to add a QSEAL certificate via API request to TPP Certficate endpoint.

After adding a certificate, the registered TPP will have assigned a set of scopes based on the provided certificate.

I.e. AISP certificate will result in account, transactions, kyc scopes, while a PISP certificate will result in payments, funds_availability scopes. The available scopes can be seen when creating an TPP Application.

Registration BerlinGroup Headers

Instruction to create BerlinGroup Signature

To register as a TPP, the first thing you must do is get a valid EIDAS certificate.

The required headers for this call are:

• X-Request-ID: Is a unique id for your call, e.g. a GUID.
  X-Request-ID => SecureRandom.uuid


• Digest: Is a hashed and encoded value of the body of the API call.
  Digest => "SHA-256=" + Digest::SHA256.base64digest(YOUR_REQUEST_BODY)


• Date: Is just the date of the call, in the following format: „Fri, 04 Feb 2022 17:16:59 GMT“
  Date => Time.now.httpdate


• TPP-Signature-Certificate: Is the cert used to sign the message.
  TPP-Signature-Certificate => Base64.strict_encode64(CERTIFICATE_PEM)


• Signature: Is the signed value of the message, and is constructed in the following way.
  Signature => "Signature keyId=" "SN=" + certificate.serial,"DN=" + certificate.issuer", "algorithm" = "rsa-sha256", "headers" = "x-request-id digest date", "signature" = Base64(RSA-SHA256(signing string))
  • Signature keyId: Is combinated string of Certificate Serial Number and Certificate Issuer. Certificate serial number must be in decimal notation.
    Signature keyId => "SN=" + (CERTIFICATE_SERIAL),"DN=" + (CERTIFICATE_ISSUER)"
  
  
  • Algorithm: Is SHA256 algorithm.
    Algorithm => "rsa-sha256"
  
  
  • Headers: Selected required headers.
    Headers => "x-request-id digest date"
  
  
  • Signature: Is Base64 encoded string.
    Signature => Base64.strict_encode64(PRIVATE_KEY.sign("RSA-SHA256", SIGNING_HEADERS))
    
    SIGNING_HEADERS: Is required headers with values. Where `\n` is used as headers delimiter.
    SIGNING_HEADERS => "x-request-id: 5b2d13ae-f7e8-4088-b98f-0acf05ac3303\n" + "digest: SHA-256=yL4tyKu3UC0isKZgiGYDu1guWcLIJyZkLQUb1e35zYw=\n" + "date: Wed, 23 Mar 2022 10:03:06 GMT"
    
  
  

API Endpoints

The table below describes the list of all API endpoints available at Salt Edge PSD2 Compliance Solution. The endpoints are based on NextGenPSD2 Framework version 1.3.6. also known as BerlinGroup Standard. BerlinGroup endpoints are name-spaced after selected provider_code. Ex: for MPS Retail Sandbox, the endpoints will start with /mps_retail_sandbox/api...

Remark: Note that the /consents endpoint optionally offers to grant an access on all available payment accounts of a PSU. In this case, this endpoint will deliver the information about all available payment accounts of the PSU at this ASPSP.
/v1/accounts/refresh	POST	This endpoint is responsible for starting the process of refreshing account information data on Salt Edge PSD2 Compliance Solution side. Due to asynchronous nature of this action, TPP has to poll the status of this process using Accounts RefreshStatus endpoint.

During any request or flow originating either on TPP or Salt Edge PSD2 Compliance side, a number of errors may appear. In order to standardize errors while still giving some degree of freedom in explaining an error callback, parameters should include both error_text and error_code. Error message serves the purpose of communicating the issue to the Customer, whereas error class should be used by TPPs in order to be able to handle various scenarios.

Contents of the error_code are entirely up to the Provider, they may even be localized. However, values sent within error_text parameter should be from the standardized list. This list may and will be extended over time.
