How to Create a Pull request from my Forked repo to Main repo via Bitbucket APIs

[aejazahmed_mohammed]

Hi Team,
Can you please help me how to raise a pull request automatically via APIs, this is to be used in my program that whenever a new repo is created via Jenkins job, i need to create a pull request for that repo name.

I had forked the original repo as i cant create separate branch due to limited permission issues. (Bitbucket version is 7.21.1)

In Browser the repos are:
=================

My Forked repo(Source) : 'https://URL/stash/users/MyUser/repos/RepoName/browse'
Original repo (Destination) : 'https:/URL/stash/projects/ProjectName/repos/RepoName/browse'

For Cloning the repos are:

=================
My Forked repo(Source) : 'https://URL/stash/scm/MyUser/RepoName.git'
Original repo (Destination) : 'https:/URL/stash/scm/ProjectName/RepoName.git'

How can i raise a pull request from source repo to destination repo?
Also please suggest how to add content/data in a file(eg: abc.json) of my forked repo and raise a PR to the main repo so that content/data are added to main repo file(abc.json) after approval/review, all this via APIs
