Hello, I'm trying to set up a webhook that will trigger a github action. The github action builds and deploys my side. I've followed the instructions in these two posts: - Using webhooks to fire Github action - #6 by Fares - Setting Authorization Header in Webhooks Still getting a 404 or 422 error…

Hey Conner, What did you set the 'key' and 'value' for your headers in Primsic as? Thanks.

I've also just been playing with this same workflow. Unfortunately it looks like the prismic payload isn't compatible with the current Github dispatch endpoint :frowning: It's not just the mismatch between type and event_type, github also won't accept secret, and other extra fields…

Welcome to the community, Daniel. Thanks for the extra info, I'm going to report this to the team as a Request For Change, if/when we have any updates we'll let you know here.

This is an issue that I was tracking for around 1.5years in Prismic. I saw many requests on this topic from various users. I send the same in feedback email as well. I still don't see any solutions. Is it something Prismic planning to do? Is there any realistic timeline? Thanks, Subin

Hi @subin01 , We are tracking this in our backlog, but due to other high-priority tasks, we cannot get to it just yet. We will of course provide you with an update as soon as possible. Thanks.

@Phil Any update on this issue?

@Phil what about now? There are threads going back 3 years at least asking about custom bodies for webhooks — a necessary feature to trigger GitHub actions. Any chance this sees the light of day in 2023?

Hello @wyatt and others, Thanks a lot for your suggestions for enhancements. While we don't have immediate plans to incorporate this feature, many of our users have found a viable alternative. With the growing trend towards serverless architecture, you can achieve payload customization using a pro…

Thanks @renaud , the sample implementation is useful — but I will say that expecting users to run, maintain, and pay for additional infrastructure just to make webhooks work with an extremely common CI provider is preeeeeeetttty lame from a product standpoint.

Hey @amacpherson, we do still recommend having a proxy between Prismic and Github for the time being. We're aware of the user need for this and have an open feature request for it, thanks for adding your voice to it!
