STET is proud to release an update (V1.2.3) of its PSD2 API.
This update provides several fixes and clarifications taking into account the comments and questions that have been addressed after the release of the initial version (V1.2.2) on 2017 July 13th.
Please see the Change Log document for complete specifications of the applied changes.

Created accordingly to the new Payment Services Directive (PSD2), this API aims to provide a secure and easy-to-use set of services to be implemented by European ASPSPs (Account Servicing Payment Service Providers) on the server side for:

  • AISP (Account Information Service Providers)
  • PIISP (Payment Issuer Instrument Service Providers)
  • PISP (Payment Initiation Service Providers)

It also provides authentication, authorization, proof management and fraud detection oriented features.

This API has been built with the latest technology standards using REST, OAuth2, JSON and HTTP-signature. It relies on ISO20022 elements for structuring the data to be exchanged between TPPs and ASPSPs.
