To use Unico IDPay, it is necessary to authenticate using the access token obtained through the OAuth2 authentication system.

The OAuth2 authentication system of Unico supports server-to-server interaction between a web application and the Unico services. For this scenario, you need a service account, which is an impersonal account that belongs to your application and not an individual user. The administrators can request that a service account be authorized to access data from a user account.

The Authentication guide describes how an application can complete the OAuth2 server-to-server authentication process through the HTTP protocol.

It is mandatory to send it in the header of your requests through the Authorization key.
