Hi there. I have three branches on my bitbucket repo, master, staging and develop. I _only_ want my workflow to run when a pull request is merged in to my staging branch. Previously bitrise would trigger on pushes to develop, staging, all sorts, which I didn’t want as every little commit would use up one of my monthly builds. I only have ‘Pull request: merged’ ticked in my bitbucket outgoing webhook. I do this because I only allow commits and pushes to develop; master and staging may only have a pull request merged in from the bitbucket web interface. ![](https://us1.discourse-cdn.com/flex016/uploads/bitrise/original/1X/cd76d820e9c27e905bb5271be05377f544ea7f36.png) The webhook gets called OK but now I get a 400 response from Bitrise, and my build isn’t triggered: > { > “error”: “Failed to transform the webhook: X-Event-Key is not supported: pullrequest:fulfilled” > } ![](https://us1.discourse-cdn.com/flex016/uploads/bitrise/original/1X/eb1888ee82fa5ee1addebbce6a4c0336698b49bb.png) ![](https://us1.discourse-cdn.com/flex016/uploads/bitrise/original/1X/38a90ac2713d932fe13a4ee54b0963435319268f.png) I can PM the request body if needed - I won’t paste it here as it has a lot of my app & repo specific details in. Thanks Nick ---

Thanks for the question @souleh! So, the thing about Pull Request merges is that it is actuall a **change** (git push) on the **target** branch. When you merge the PR that generates a new commit on the PR’s target branch, and this is handled as a Git Push on [bitrise.io](https://www.bitrise.io) / in the Trigger Map. What you want for the use case you described is: 1. Enable the **Repository** -\> **Push** option of the Bitbucket Webhook 2. Limit what kind of pushes to build using the Trigger Map on [bitrise.io](https://www.bitrise.io) To only build changes of the `staging` branch: ```auto trigger_map: - push_branch: "staging" workflow: primary ``` See: [http://devcenter.bitrise.io/webhooks/trigger-map/#how-to-build-only-a-single-branch](http://devcenter.bitrise.io/webhooks/trigger-map/#how-to-build-only-a-single-branch) - this trigger map config will only build code pushes and only on the `staging` branch. More information and example configs: [http://devcenter.bitrise.io/webhooks/trigger-map/](http://devcenter.bitrise.io/webhooks/trigger-map/) Let us know if you’d have any questions! ---

Hi @MeGaPk > [@MeGaPk](#): > > but have error in Bitrise server standalone, not cloud (stash) You meant standalone / self hosted **Bitbucket** , not Bitrise, right? In that case please see & vote/comment: [Add support for Bitbucket Server webhook format](http://discuss.bitrise.io/t/add-support-for-bitbucket-server-webhook-format/25) ---
