What is an access token?

Access tokens are used in token-based authentication to allow one system access to another system’s API by gathering and providing the required security data for clearance.

An application receives an access token after a user successfully logs in to a system, then passes the access token as a credential when it calls the target API. Passed tokens inform the API that the user is authorized to access and perform specific actions by the scope that was granted during authorization.

In Infobip, we use access tokens to connect to other communication channels to authenticate the connection between our platform and a 3rd party platform. This allows us to create communications from your business accounts using Infobip solutions.
