This would be also be useful for calling an existing API a user can’t customise.
An example I have is that I would like to be able to trigger a Github workflow (via the workflow_dispatch or repository_dispatch events on the REST API) via a GraphCMS webhook. This requires that the payload have a “ref” or “event_type” field. Currently, to achieve this functionality I need to send a webhook to an intermediary lambda to replace the payload with a simple JSON object.
This feature already exists in other headless CMSs: DatoCMS, Contently
