This section of the documentation is dedicated to explaining the authentication models present in our APIs. It is important to note that depending on the endpoint used by your establishment, you must use an authentication model appropriate for the method being used.
For example, when using resources such as "Establishments," "Anticipations," "Payments," "Payment Links," "Recurring Payments," "Settlements," and "Pix," payment authentication is required.
Payment authentication
Payment Authentication is a single-key authorization and authentication model responsible for identifying the client and validating their access to the endpoint. In this authentication method, there is no need to generate a temporary session token, as it is based on the Basic Authorization standard.

How to obtain the unique payment authentication key?

If you still haven't found your key, don't worry. You are likely a new store and your access is still pending approval and certification. Soon, your integration will be approved, and your integration key will be enabled.
