Overview

PSD2 Compliant XS2A Payment services (PSD 2) - Directive (EU) 2015/2366 API based on Berlin Group NextGenPSD2 XS2A Specification v1.3 (BGS).

SCA Approach

We use REDIRECT SCA approach with implicit start of the authorisation process (detailed description and schemes can be found in page 54 for payments and page 108 for consents of BGS document). Implicit process means that we automatically create authorisation resource and return this information in the response.

Consent Model

We let PSU to choose what he allows in the consent, so information passed in the consent works only as a reference to mark checkboxes. In case consent information contains accounts that do not belong to user or does not exist in the system, or overall consent is passed without accounts, then checkbox’s will not be marked for the PSU after he logs into the application.

Differences From Berlin Group Standard

Different Versioning Approach

Instead of path versioning that is mentioned in the BGS documentation, we use header versioning. More information about this can be found later in the document (API Versioning).

Optional parameters

Get account transactions endpoint uses two optional parameters for paging:

  • pageSize – sets record count per page;

  • page – sets which page is displayed;

Differences in responses

Get account transactions endpoint uses different response structure. Instead of returning two lists (pending and booked) in the response, we simply return a single list with additional boolean parameter peding in the transaction record, where value of true indicates that transaction is pending and value of false that is booked.

API Versioning

Current API version: 1

API uses X-API-Version header parameter to determine current API version. If this parameter is not passed, the system will return 404 Not Found error. Version header usage can be found in examples. We use only major version of API, so all changes that does not break backward compatibility does not increase version number. New API version is added on when non backward compatible changes are made:

  • Adding restrictive logic (e.g. making fields mandatory, business validation logic);

  • Removing fields;

  • Removing endpoints;

Upcoming major API versions are instantly released to production and will run in parallel with old version. Old version will be available for at least 6 months before removal.

All upcoming documentation will be provided in the documentation page, so it is advisable to check this page once a month.

HTTP Response Codes

The HTTP response code is communicating the success or failure of a TPP request message. The 4XX HTTP response codes should only be given if the current request cannot be fulfilled, e.g. a payment initiation cannot be posted or account transactions cannot be retrieved. A request to get the status of an existing payment or a consent usually returns HTTP response code 200 since the actual request to retrieve the status succeeded, regardless if that payment or consent state is set to failure or not.

This specification supports the following HTTP response codes:

Status code Description

200 OK

PUT, GET Response Codes

The POST for a Funds request will also return 200 since it does not create a new resource.

DELETE Response Code where a payment resource has been cancelled successfully and no further cancellation authorisation is required.

201 Created

POST response code where Payment Initiation or Consent Request was correctly performed.

204 No Content

DELETE response code where a consent resource was successfully deleted. The code indicates that the request was performed, but no content was returned.

400 Bad Request

Validation error occurred. This code will cover malformed syntax in request or incorrect data in payload.

401 Unauthorized

The TPP or the PSU is not correctly authorized to perform the request. Retry the request with correct authentication information.

403 Forbidden

Returned if the resource that was referenced in the path exists but cannot be accessed by the TPP or the PSU. This code should only be used for non-sensitive id references as it will reveal that the resource exists even though it cannot be accessed.

404 Not found

Returned if the resource or endpoint that was referenced in the path does not exist or cannot be referenced by the TPP or the PSU. When in doubt if a specific id in the path is sensitive or not, use the HTTP response code 404 instead of the HTTP response code 403.

405 Method Not Allowed

This code is only sent when the HTTP method (PUT, POST, DELETE, GET etc.) is not supported on a specific endpoint. It has nothing to do with the consent, payment or account information data model.

406 Not Acceptable

The ASPSP cannot generate the content that the TPP specified in the Accept header.

408 Request Timeout

The server is still working correctly, but an individual request has timed out.

415 Unsupported Media Type

The TPP has supplied a media type which the ASPSP does not support.

429 Too Many Requests

The TPP has exceeded the number of requests allowed by the consent or by the RTS.

500 Internal Server Error

Internal server error occurred.

503 Service Unavailable

The ASPSP server is currently unavailable. Generally, this is a temporary state.

Additional Error Information

In RFC7807, a standardised definition of reporting error information is described. In the following, requirements of how to use this standardised error information reporting in the context of the PSD2 XS2A interface are defined.

PSD2 fallback

The Fallback solution is a set of API-s as a alternative for exiting Nano PSD2 solution. PSD2 Fallback is based on Nano Internet Banking API It contains the following functions:

authenticating TPPs based on QWAC certificates
limiting access to respective functions based on the TPP role
customer authentication and authorization using Nano IB supported security means m-signature, Vasco Digipass, SMS+password
fetching customer accounts information for AISP
initiating payments for PISPs

The Fallback solution does not have:

customer consent management
fetching funds confirmation information for PIISPs
agent features are not supported

List of endpoints:

psd-fallback/auth/login
psd-fallback/auth/logout
psd-fallback/auth/resend
psd-fallback/operations/(:id)/confirmation
