Bitbucket Post Webhook helps you

The Bitbucket Server and Data Center app allows users to send JSON payloads to external systems like Jenkins, customer scripts, and Serverless functions. It supports triggering Azure DevOps pipelines and sending Microsoft Teams notifications.

Users can configure global, project, and repository rules and authenticate using Basic, Bearer, or Kerberos authentication. The app also supports Mutual TLS and allows users to filter events using various criteria, including event type, committers, repository and branch masks, and from/to branches.

Users can also use the API to create rules and include query string parameters in their requests. The app has the option to skip SSL and URL validations and to skip notifications for personal projects and repositories.

Main functionality

Frequently Asked Questions

You can find Bitbucket Post Webhook Frequently Asked Questions here.

Project configuration

Important: project-level configuration by default overrides global configuration.

The configuration screen is available for project and global admins at Project settings → Workflow → Post Webhooks.

At the project level, you can also see all repository rules.

To set up webhook posts, select the events and filters you want to notify your system. It can be the Jenkins branch source plugin or any other system.

The configuration is available at Repository → Settings → Post Webhooks.

When you start with an empty list, you must add a new configuration.

You need to click “Add webhook“. Here is a picture of how it looks.

Here you need to setup:

• The title - what is the name of the configuration (can be something random or meaningful with your repo or person name). Our advice is to name something meaningful to you and your team so that it can be understood later easier.

• Override project and global settings. It is On by default. You can use this setting to override the project and global setup. If it is off, the project and global-level configuration will take precedence.

• The URL - where the data should be sent to. F.e.

  • You can skip SSL verification and test connection with additional auxiliary settings.

  • {project.key} variable can be used as part of the URL to be replaced by the Bitbucket project’s key.

  • {repository.slug} variable can be used as part of the URL to be replaced by the Bitbucket repository’s slug.

  • You can change the HTTP method to be used. Note: getting the HTTP body is NOT sent.

• Configure basic authentication and Azure DevOps Pipelines token.

• Enable mutual TLS verification or skip the SSL certificate validation for self-signed certificates.

• Trigger Azure DevOps pipelines.

• Committers to ignore (full match) - the comma-separated list of Bitbucket user names that should NOT trigger an event. Important: not display names, but usernames. This is often used to ignore pushes from your continuous integration user. For instance, you could put there jenkins-user.

• From branches to consider (regex) - the comma-separated list of Bitbucket branch regular expressions that should be considered when filtering events. For instance, release/*, tag/*, etc.

• Destination branches to consider - the comma-separated list of Bitbucket branch regular expressions should be considered when filtering events for pull requests only. For instance, release/*, tag/*, etc.

• From branches to ignore (regex) - the comma-separated list of Bitbucket branch regexes that should be ignored. For instance, release/*, tag/*, etc.

• Destination branches to ignore (regex) - the comma-separated list of Bitbucket branch regexes that should be ignored. For instance, release/*, tag/*, etc.

• Active - should be On if this configuration is to be used.

• Skip CI - a setting that allows skipping notifications for the pull requests if [ci skip] or [skip ci] is present in the pull request's title or description. The same applies to the commit-related events, and the commit message is checked.

• File path pattern - comma-separated list of file paths. Only commits on these file paths will trigger the webhook. For example, src/java/.*/src/main/resources/.*properties will trigger events only for the changes in the properties files.

Only the events related to the files take this setting into consideration.

• Skip personal - allows skipping of the events from personal projects and repositories. Skips forks.

• Include projects - a comma-separated list of Bitbucket project keys that will trigger this event.

• Exclude projects - a comma-separated list of Bitbucket project keys that will be IGNORED for this event. This could be used with the combination of Include projects empty (include all).

• Select the list of the events that you want to notify your external system about.

For instance, you don’t want to notify Jenkins about the changes made by the Jenkins user to not trigger cyclomatic build dependency, so you will add the Jenkins user to the committers to ignore.

Enable multiple rules on the repository level and other settings

Contact your Bitbucket administrator to enable this.

Query string parameters support

The following query string parameters are supported:

• repository.slug - the repository slug

• project.key - the project key

• branch.name - the branch name

• pullrequest.frombranch - the from branch name of the pull request (relative git path) - f.e. refs/heads/bug/someBug

• pullrequest.frombranch.name - the from-branch name - f.e. someBug.

• pullrequest.tobranch - the to-branch name of the pull request (relative git path) - f.e. refs/heads/master

• pullrequest.tobranch.name - the to-branch name - f.e. master.

• pullrequest.url - the pull request url

Build status event handling

Bitbucket build status API provides the only commitId and Bitbucket Post Webhooks needs to find rules to process an event. Because the App cannot get repository information, it uses two approaches to find the repository by commit id:

• Default (since 3.12.23): we cache the commit id and repository id to find the repository id by commit id in O(1) time.

• Repository search (default before 3.12.23): The app scans all repositories, and projects, globally where rules exist with Build status notification enabled. This approach is not very performant when a huge repository because it results in a repository scan. This approach has been disabled by default since version 3.12.23. You can enable it in the global setting (“Enable repositories scan to find commit for build status“ checkbox).

Trigger Azure DevOps Pipelines Cloud and Server (On-Premises)

You can use Bitbucket Post Webhook App to trigger Azure DevOps Pipelines.

You need to generate an API token that allows the execution of the required action. https://docs.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=preview-page#create-a-pat

It should allow triggering the build pipelines, nothing more. No code access is required. Only Read and Execute pipelines.

Please set the URL in the provided field.

And specify the URL to the pipeline in the following format:

The build triggers the source branch. For instance, if you create a branch feature/DEV-123-azure-DevOps-confluence-fix the branch ref will be passed to the pipelines that should check out/clone the right branch.

Cloud: The url should match the following pattern https://dev.azure.com/{ORG_NAME}/{PROJECT_NAME}/_build?definitionId={PIPELINE_ID}

Server: The url should match the following pattern https://yoursever/{COLLECTION}/{PROJECT_NAME}/_build?definitionId={DEFINITION_ID}

Azure DevOps Pipelines parameters

Additional details are here.

The following parameters are passed from Bitbucket to Azure DevOps Pipelines:

• projectKey

• projectName

• branch (the branch name)

• repositorySlug (the repository URL friendly name)

• repositoryName

• commit (optional commit hash)

• commitMessage (optional commit message)

• sourceBranch

• destinationBranch

• userDisplayName

• userSlug

• eventType

• pullRequestId

• pullRequestTitle

• pullRequestDescription

• pullRequestState

Dealing with removed/moved repositories

From version 3.12, App updates or deactivates configurations when a repository or a project is renamed or moved. Which highlights the rules which may need a fix.

Not valid configurations are marked in yellow and shown only at the global level so that the global admin can amend or delete them.

In the older versions, you may see RepositoryMovedException. Follow the document below to delete/change older issues. However, the best approach is to update to the latest version and fix the highlighted rule in the Global configuration.

Bitbucket RepositoryMovedException

Kerberos support

KERBEROS is a experimental API. Be sure Bitbucket was started with proper configuration e.g.: JAVA_OPTS="-Djavax.net.ssl.trustStore=/etc/pki/java/cacerts -Djava.security.krb5.conf=/etc/krb5.conf -Djavax.security.auth.useSubjectCredsOnly=false"

Afterwards, you can specify your username and password in the authentication section of the configuration screen.

Microsoft Teams support

We do recommend you to use Advanced Microsoft Teams Bitbucket Connector for Microsoft Teams integration.

Incoming webhook generation

Generate an incoming webhook URL for the channel you want to receive notifications.

Go to the Microsoft Teams channel configuration and add a connector.

Find an Incoming Webhook and add one. Put the name as Bitbucket and set the Bitbucket logo.

Set the name and the icon of the Connector.

Copy the webhook URL that will be used later on during the configuration process.

Setup

On any level (repository, project or global) you can paste a newly generated URL. No checkboxes are necessary. The App supports the old and new formats of Incoming Webhook URLs.
