Azure DevOps pipeline task to update a file and check-in TFS

You could invoke the REST API Pushes - Create to update the file and check-in the same in TFS branch with powershell scripts.

1. Go to the Agent Phase and select Allow Scripts to Access OAuth Token. See Use the OAuth token to access the REST API:

2. Add a PowerShell task in your build pipeline to get the latest commit on the branch you want to update the file and check-in:

   GET https://{instance}/{collection}/{project}/_apis/git/repositories/{repositoryId}/commits?api-version=5.0&branch={BranchName}&$top=1
   

3. update the file and check-in the same in TFS branch via REST API:

   POST https://{instance}/{collection}/{project}/_apis/git/repositories/{repositoryId}/pushes?api-version=5.0
   

Body (application/json):

{
  "refUpdates": [
    {
      "name": "refs/heads/$(BranchName)",
      "oldObjectId": "[step 2 commit ID]"
    }
  ],
  "commits": [
    {
      "comment": "Added a few more items to the task list.",
      "changes": [
        {
          "changeType": "edit",
          "item": {
            "path": "/tasks.md"
          },
          "newContent": {
            "content": "# Tasks\n\n* Item 1\n* Item 2\n* Item 3\n* Item 4\n\nIf you need to add more, update this file and add them!",
            "contentType": "rawtext"
          }
        }
      ]
    }
  ]
}

As the test result:

Note:

• You need to parse quotes if file content contains quotes (\"test\"), the same as other special charters.
• Use the Repositories - List to get the repositoryId.

Hope this helps.

Based on the above suggestions. I have added the below mentioned code

$requestBody = @{
changes=
  @(@{
    item= @{
      path= "$/SMT_Project/" + $branch + "/SMT/BPOSE_WebApp/Deal/LandingPage.aspx"
      contentMetadata= @{
        encoding= -1
      }
    }
    changeType= "add"
    newContent= @{
      content= $EncodedText
      contentType= "base64Encoded"
    }
  })
  comment= "Updated LandingPage.aspx with script for deployment"
  } | ConvertTo-Json -Depth 4
$headers = @{
    Authorization = "Bearer $env:SYSTEM_ACCESSTOKEN"
}

$headers.Add("Accept", 'application/json')

$requestBodyJson = ($requestBody | ConvertFrom-Json)

Write-Host 'headers - ' $headers
Write-Host 'requestBody - ' $requestBody
Write-Host 'requestBodyJson - ' $requestBodyJson

$postRes = Invoke-WebRequest -Uri https://dev.azure.com/sm10/_apis/tfvc/changesets?api-version=5.1 -ContentType "application/json" -Headers $headers -Method POST -Body $requestBody -Verbose

But I have not received and response from the web request also I have not received any errors. Please do let me know anything is missing.
