CI/CD pipelines Azure devops automatic merge after deploy release

Question

I have a classic env. setup like following:

I have 2 branches: Develop and Master.

Is there any way in Azure DevOps to setup the following rule:

1. When a deploy is succeeded on dev environment (defined in the release pipeline of azure devops) ------> create automatically a pull request to merge develop into Master.

2. or the other one: if a Build of develop branch is succeded -------> create automatically a pull request to merge develop into Master.

Any help will be appreciated.

Edit:

I just uploaded an extension that does it: https://marketplace.visualstudio.com/items?itemName=ShaykiAbramczyk.CreatePullRequest

You can use Azure DevOps Rest API to create a Pull Request, so in the end of the Build / Release add a PowerShell task that do it, for example:

$body =  @{
             sourceRefName= "$(Build.SourceBranch)"
             targetRefName = "refs/heads/master"
             title = "PR from Pipeline"
     }

$head = @{ Authorization = "Bearer $env:SYSTEM_ACCESSTOKEN"  }
$json = ConvertTo-Json $body
$url = "$(System.TeamFoundationCollectionUri)$(System.TeamProject)/_apis/git/repositories/$(Build.Repository.Name)/pullrequests?api-version=5.0"
Invoke-RestMethod -Uri $url -Method Post -Headers $head -Body $json -ContentType application/json

You need to Allow scripts to access the OAuth token (check the checbox in the Agent Job options):

Results:

I put the basic parameters in the body (from branch, to branch, title) but you can add more parameters like reviewers, check the docs here.

Thank you for your answer, can please provide more details about this : "you can script this yourself using the oauth token, or using your own auth to issue a request against the api." thanks

I've been doing this with github, you just need to call the api for merge: developer.github.com/v3/repos/merging

If you receive the "You need the Git 'PullRequestContribute' permission to perform this action" error upon running the script in a release pipeline, who do you grant these permissions to?

[Shayki Abramczyk]

@DickyMoore To the build service account, did you get the error even you enable the "Allow scripts to access....."?

As mentioned in the documentation, you can add a reviewer with the following: "reviewers": [{"id": "d6245f20-2af8-44f4-9451-8107cb2767db"} How can I get the Id of the user I want to add as reviewer??

@MohamadMousheimish you can check the code of my extension that mentions above, there are different ways, check there.

Receiving this error with @ShaykiAbramczyk extension > "message":"TF401179: An active pull request for the source and target branch already exists."

[Shayki Abramczyk]

@MANZARBEITIA it means that there is already PR open...

[MANZARBEITIA]

@ShaykiAbramczyk this issue only happened using YAML, when I used the classic editor it worked as expected.

@MANZARBEITIA and the settings are the same? please open an issue in my GitHub github.com/shayki5/azure-devops-create-pr-task/issues
