The access token API endpoint is used to get an access token. It enables the TPP to authenticate to the Fintecture Authentication Server.

There are 2 types of grant_types, authorization_code and client_credentials, depending if you require access to the AIS, PIS or Customers resources.

In case of an AIS scope it is provided in exchange to the code received in the /authorize endpoint. For the PIS and Customers ones, it will be granted according to client credentials.

Once provided, validity of access token is 1h.
