Setting Authorization Header in Webhooks

[online (deming factor)]

Thanks so much @Phil, that is greatly appreciated

While they are looking at Webhooks can they also add support for setting Headers and a Body, as raised by @ gctravelapp here.

Webhooks - Sending a payload body?

Hi everyone, I am hoping to create a webhook to hit a workflow dispatch event (which then triggers a re-build of our Gatsby site) as per the docs here: Actions - GitHub Docs This endpoint requires 'ref' to be set in the body, however Prismic's Webhooks interface doesn't provide a way to send body parameters. Is there a way to do this or do I have to set up a proxy?
