The "Account Information" API resources can only be used by Payment Service Providers (PSP) having a Account Information Service Providers (AISP) role. 

In order to provide a service to users of payment informations services under PSD2 directive, you must be a licenced PSP such as credit institution, electronic money institution, and payment institution. This status is delivered by the financial authorities of the country where the request is made ; in France it is the "Autorité de Contrôle Prudentiel et de Résolution (ACPR), under the supervision of the Banque de France regulatory body :


Obtaining and maintaining such agreement requires rigorous procedures in order to give strong guarantees to the account informations services users. The forms are provided on the ACPR website : https://acpr.banque-france.fr/en/authorisation/banking-industry-procedures/all-forms 

Once the agrement is granted, the Organisation Identifier (OID) given by the national authority has the following format :


"PSD" as 3 character legal person identity type reference;

2 character ISO 3166 country code representing the NCA country;

hyphen-minus "-" (0x2D (ASCII), U+002D (UTF-8)); and

2-8 character NCA identifier (A-Z uppercase only, no separator)

hyphen-minus "-" (0x2D (ASCII), U+002D (UTF-8)); andPSP identifier (authorization number as specified by NCA). 

This OID is very important to identify yourself as a TPP :

  • using STET API requests as OID is included in the parameter "client_ID" ;
  • using mutual authentication (TLS) as OID is included in eIDAS certificates to be delivered to the bank (see below).

You also need eIDAS (electronic IDentification And trust Services) compliant certificates delivered by a Qualified Certification Service Provider (QTSP, see list available on https://webgate.ec.europa.eu/tl-browser/#/).

In order to be able to consume PSD2 API published on our 89C3 Portal, you have to forward us using .pem format
