How to add branch policies using powershell Invoke RestMethod - powershell

Question

We have PowerShell script that will automate creating branch.
Now we are trying to automate branch policies using api using PowerShell Invoke-RestMethod.
We have option to manually add policies using cross repository policies, but we have build validation enabled for repositories which is different for each repo.
I'm able to get the policy configurations using GET https://dev.azure.com/$organization/$project/_apis/policy/configurations/repo=$repoName&api-version=6.0
But don't know how to get the get the particular value and add policies.

Answer 1

You can use the Configurations - Create Rest API:
POST https://dev.azure.com/{organization}/{project}/_apis/policy/configurations/{configurationId}?api-version=6.1-preview.1
In the body you specify the branch policy you want to add, for example - build policy:
{
"isEnabled": true,
"isBlocking": false,
"type": {
"id": "0609b952-1397-4640-95ec-e00a01b2c241"
},
"settings": {
"buildDefinitionId": 5,
"scope": [
{
"repositoryId": null,
"refName": "refs/heads/feature",
"matchKind": "prefix"
}
]
}
}
In the above body you add branch (build) policy to branch feature that requires build 5 to pass.
You cans see all the available policy types in the Types - List api.

To add the Build validation in Branch Policy, you could refer to the following PowerShell Sample:
$token = "PAT"
$url="https://dev.azure.com/{OrganizationName}/{ProjectName}/_apis/policy/configurations?api-version=6.1-preview.1"
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($token)"))
$JSON = #'
{
"type":{
"id":"0609b952-1397-4640-95ec-e00a01b2c241"
},
"revision":1,
"isDeleted":false,
"isBlocking":true,
"isEnabled":true,
"settings":{
"buildDefinitionId":592,
"displayName":null,
"manualQueueOnly":false,
"queueOnSourceUpdateOnly":true,
"validDuration":720,
"scope":[
{
"repositoryId":"RepoID",
"refName":"refs/heads/BranchName",
"matchKind":"Exact"
}
]
}
}
'#
$response = Invoke-RestMethod -Uri $url -Headers #{Authorization = "Basic $token"} -Method POST -Body $JSON -ContentType application/json
