How to get Pull request title as a Variable

[tony.thomas]

Hey Team,

I would like to know how to get the Pull Request title as a Variable in Pipeline.

The below document gives a list of default variables, but can't find what I am looking for.

You can get the title of a pull-request via the API.

https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/%7Bworkspace%7D/%7Brepo_slug%7D/pullrequests/%7Bpull_request_id%7D

The BITBUCKET_PR_ID is available as environment variable if the pipeline is a pull-request pipeline.

I am getting the error 

Access denied. You must have write or admin access.

and I am the Admin of the Repo and Workspace.

Also is there a way I can get the Pull request title as a Variable just like BITBUCKET_PR_ID?

[ktomk]

@tony.thomas Yes, as written, you can get the PR title as output from the API. The output can be assigned to a variable (e.g. with utilities like jq or similar).

This requires using the API successfully first. Please check the existing Q&A and support resources for that incl. trouble-shooting. Some more references:

• Bitbucket API throws 'You must have write or admin access' when search for PRs
• How do I call Bitbucket API from pipeline context?
• Bitbucket API Authentication methods

If it still does not work for you, please provide the example.

Example with the curl and the jq utilities (working API authentication with necessary access rights required):

 - |
   BITBUCKET_PR_TITLE="$(\
     curl ... -fsS -H 'Content-Type: application/json' \
    "https://api.bitbucket.org/2.0/repositories/${BITBUCKET_REPO_FULL_NAME}"\
   "/pullrequests/${BITBUCKET_PR_ID}" \
     | jq -r '.title')" \
     ; test "$BITBUCKET_PR_TITLE"

@tony.thomas , you can add on the curl command provided by @ktomk a header for bearer token:

--header 'Authorization: Bearer XXXXXX'

And replace XXXXXX with a token you generate on "Repository Settings > Access Tokens".
