When using the repository notification feature, Quay does not send allow to specify authentication credentials for notification of type webhook POST. Only unauthenticated webhooks calls are possible today. This hinders the ability to use Github's repository_dispatch event as a callback to successful builds. The event itself is needed to trigger Github Actions which is similar in nature to other Ci/CD pipelines (Github Actions). There is a project that currently does the conversion and details of the issue are explained there:

Is this something we could add to Quay?
