It's been observed that indexing of pull requests or branches in a repository gets interrupted due to application link or connection error. This may result in incomplete or inaccurate data in the Jira Development Panel overview. 

To remediate this, the reindex API below deletes the index and recreates it including only the Jira issue keys from the pull request title or the branch name. However this API needs to be triggered for each repository affected:

<bitbucket URL>/rest/jira-dev/1.0/projects/<project key>/repos/<repository slug>/reindex

The request is to have an API to fire the reindex for all repositories in Bitbucket, instead of doing multiple calls for each repository.
