Use the /AuthSecret endpoint if you are a client of Flinks and want to grant access for a partner to retrieve data that is processed by Flinks. This endpoint generates an AuthSecret that your partner can use to securely access Flinks APIs.
Each partner only needs one AuthSecret for the duration of time they are accessing data through Flinks. Call this endpoint once for each partner you are providing access to.
In addition to an AuthSecret, this endpoint also returns a PermissionId that revokes access to Flinks APIs by disabling the AuthSecret. Save the PermissionId on your side. For more information about revoking access to Flinks APIs, see the /AuthSecret/Disable endpoint.
