API Errors with SyRegistry Authentication

Note: Anthology Student 22.0 introduces an alternate method for the authentication of CampusLink API calls. The new authentication method does not use the SyRegistry table. For details see Authentication for CampusLink API Calls.

If the below error is received in Workflow Composer and/or in the logs, the API Password that is in the SyRegistry table is not correct.  To sync the password, log in to the Portal Admin Console and update the password for the API user.

API User Permissions

The API User specified in the SyRegistry table has to have permissions to execute the CampusLink APIs.  This user must exist in Anthology Student and be part of a group other than the Administrator group that has full permissions to the Daily menu.  This user also needs to be assigned the proper Activity Security and Document Security  policies.

API Key – Access Denied Error

If the API keys are not set up correctly, an "Access denied" error will be seen in the Renderer log, for example, when a Forms Builder workflow calls the Anthology Student activity.

Solution: Ensure that the API keys across all products match.
