Bitbucket webhooks with custom payload?

[Charlie Misonne]

I need to execute a http request when a pull request in created in Bitbucket DC. The request will be received by an external application.

This can be done with the webhooks feature but I do not see any way to define a custom json payload. Bitbucket will always send it's own predefined JSON. Is that correct?

If that's really the case the only way to use the webhooks is when your target application expects that exact format?

I don't think you can customize the payload.

Instead you could try one of these:

1. Implement a little "proxy" in between Bitbucket and target system. This proxy would receive the built-in webhook's payload, and transform it to the "dialect" expected by the target system. There are many ways to build something like this, but it can only be done if the built-in payload carries every piece of information that the target system expects.
2. I think you can have automation rules triggered by the "pull request created" event. If so, then you can use Send web request automation action to send a request to the target system. This action allows customizing the request body, so it could work with your target system, too.
