To get access to the webhook headers on Zapier, I think you will need to use the ‘Catch Raw Hook’ option for the webhook on Zapier. This topic gives an example of how to do that for a User Event webhook: [Create a Salesforce lead via Zapier when a user signs up on Discourse](https://meta.discourse.org/t/create-a-salesforce-lead-via-zapier-when-a-user-signs-up-on-discourse/109301). Setting up a Zap to listen for a Post Event webhook and filter out all requests where the `X-Discourse-Event` is set to `post_edited` will be quite similar.
