Bitbucket webhook events - AWS CodeBuild

Bitbucket webhook events

You can use webhook filter groups to specify which Bitbucket webhook events trigger a build. For example, you can specify that a build is only triggered for changes to specific branches.

You can create one or more webhook filter groups to specify which webhook events trigger a build. A build is triggered if any filter group evaluates to true, which occurs when all the filters in the group evaluate to true. When you create a filter group, you specify:

An event

For Bitbucket, you can choose one or more of the following events:

  • PUSH

  • PULL_REQUEST_CREATED

  • PULL_REQUEST_UPDATED

  • PULL_REQUEST_MERGED

  • PULL_REQUEST_CLOSED

The webhook's event type is in its header in the X-Event-Key field. The following table shows how X-Event-Key header values map to the event types.

Note

You must enable the merged event in your Bitbucket webhook setting if you create a webhook filter group that uses the PULL_REQUEST_MERGED event type. You must also enable the declined event in your Bitbucket webhook setting if you create a webhook filter group that uses the PULL_REQUEST_CLOSED event type.

X-Event-Key Header value Event type
repo:push PUSH
pullrequest:created PULL_REQUEST_CREATED
pullrequest:updated PULL_REQUEST_UPDATED
pullrequest:fulfilled PULL_REQUEST_MERGED
pullrequest:rejected PULL_REQUEST_CLOSED

For PULL_REQUEST_MERGED, if a pull request is merged with the squash strategy and the pull request branch is closed, the original pull request commit no longer exists. In this case, the CODEBUILD_WEBHOOK_MERGE_COMMIT environment variable contains the identifier of the squashed merge commit.

One or more optional filters

Use a regular expression to specify a filter. For an event to trigger a build, every filter within the group associated with it must evaluate to true.

ACTOR_ACCOUNT_ID (ACTOR_ID in the console)

A webhook event triggers a build when a Bitbucket account ID matches the regular expression pattern. This value appears in the account_id property of the actor object in the webhook filter payload.

HEAD_REF

A webhook event triggers a build when the head reference matches the regular expression pattern (for example, refs/heads/branch-name and refs/tags/tag-name). A HEAD_REF filter evaluates the Git reference name for the branch or tag. The branch or tag name appears in the name field of the new object in the push object of the webhook payload. For pull request events, the branch name appears in the name field in the branch object of the source object in the webhook payload.

BASE_REF

A webhook event triggers a build when the base reference matches the regular expression pattern. A BASE_REF filter works with pull request events only (for example, refs/heads/branch-name). A BASE_REF filter evaluates the Git reference name for the branch. The branch name appears in the name field of the branch object in the destination object in the webhook payload.

FILE_PATH

A webhook triggers a build when the path of a changed file matches the regular expression pattern.

COMMIT_MESSAGE

A webhook triggers a build when the head commit message matches the regular expression pattern.

WORKFLOW_NAME

A webhook triggers a build when the workflow name matches the regular expression pattern.

Note

You can find the webhook payload in the webhook settings of your Bitbucket repository.
