Is there any supported way, to route LogicApp custom connector calls with bearer token authentication through an on-prem data gateway?
Enabling the "Connect via on-premises data gateway" option within the custom connector configuration removes all options related to API key authentication.
If set to basic authentication, the gateway seems to apply an Authorization header based on the credentials set on the API connection (which does not support referencing values within a key vault).
The API endpoint of the on-prem application provides a method for requesting access tokens based on credentials, but there does not seem to be any way to utilize these tokens for further calls.
Trying to configure the connector without authentication and appending an Authorization header manually does not work either.
