French PSD2 initiative STETS publishes API specification

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.

Although developed for the French market STETS is open for everyone to be adopted.


Open Banking Regulation in UK: API Specifications

Open Banking, the implementation entity set up by the Competition & Markets Authority (CMA) to enable a new, secure way for customers to take control of their financial data and share it with organisations other than their banks, is pleased to announce the release of its Accounts and Transaction Information and Payments Initiation API Specifications.

Open Banking has developed specifications that determine how banks and building societies should enable other regulated companies to, with the customer’s express permission, access accounts and send payments. Using these standardised API specifications, banks and authorised third parties are now able to begin developing new, innovative propositions and to tailor their products and solutions to the individual needs of consumers and businesses.

These specifications are now available on

CAPS present at ECB stakeholder meeting

In June 2016 the European Retail Payments Board, a board launched by the European Central Bank (ECB), wrote a memo where she - on the basis of current question marks on the demand side of the market - proposed a possible way forward for the Payment Initiation Services. For that purpose the ECB organized in October a stakeholder meeting on Payment Initiation Services where Michael Salmony and Lars Lolk Hauge as representatives presented the open framework of CAPS showing how CAPS can realize PSD2 in a manner beneficial to all parties. The framework was well received from both sides of the market.

The concept of CAPS is being adopted and supported by an increasing number of organisations and the CAPS framework is explicitly open to all.
