I have a manual process I am looking to automate.

This process consists of

1. Going to a DevOps Project

2. Go to Repos > Files > a sub sub folder and Create a New Branch from here, based on main

3. Commit the file

4. Submit a pull request

This, when committed and the pull is done from this folder, starts a pipeline.

I have a flow which currently

1. does a GET request on

   https://dev.azure.com/<org name>/<project name>/_apis/git/repositories/<repo id>/refs?filter=heads/main&api-version=5.1

which brings back the objectID for main on this repo.

2. Using the objectID from the GET, does a POST on

   https://dev.azure.com/<org name>/<proj name>/_apis/git/repositories/<repo id>/pushes?api-version=5.1

with body of

"refUpdates": [
 {
   "name": "refs/heads/<name of new branch>",
   "oldObjectId": "<objectID from GET command"
 }
],
"commits": [
 {
   "comment": "<any name we give the file>",
   "changes": [
     {
       "changeType": "add",
       "item": {
         "path": "/<Filename>.json"
       },
       "newContent": {
"content": '<our JSON content>',
"contentType": "rawtext"}
     }
   ]
 }
]
}

3. Then does a pull request on this file using POST of

   https://dev.azure.com/<org ID>/<proj name>/_apis/git/repositories/<repo ID>/pullrequests?api-version=5.1

with a body of

```{"sourceRefName": "refs/heads/<our branch name we set in the POST>", "targetRefName": "refs/heads/main", "title": "<our title>", "description": "", "reviewers": [{"id": "<the ID for our approval team>"}]} ```

The above ‘works’ in as much as it does the steps I think I am telling it, and creates a branch for me, adds the file and it’s content, and does the pull request.

However, the instructions I have been given for DevOps itself, show that I need to go to a sub-path within the repo I am using, of 4 folders down in the files area of Repos, and create a new branch in there; then add the file to this branch, Commit it and do the pull request from here. This then, when the pull request is approved, triggers a pipeline.

I just don’t know where I can specify this sub sub folder for the branch to be created, and then have the file created on this branch from a sub sub folder…. and then do the pull request on this branch into main.
