get https://app.heedjy.com/api/apps-credentials
list the app credentials of the current user's marketplace (only admin users are authorized). You'll most likely call this endpoint to sync credentials with a CRON job. Client secrets are always encrypted at rest, with a managed heedjy key or your own key. If encryption algo is AES (default), the secret will be the concatenation of a 16-bytes initialization vector (IV) and the base-64 encrypted key.
