Troubleshooting steps to fix the 400 Bad Request error:

Don’t worry; we’re not going to leave you hanging! Follow these steps to identify and resolve the issue:

Step 1: Check the Azure DevOps and Teams configurations

Ensure that your Azure DevOps and Teams configurations are correct and up-to-date. Verify the following:

• Azure DevOps organization and project are set up correctly
• Teams channel is connected to Azure DevOps
• API keys and tokens are valid and properly configured

Step 2: Review the request body and headers

• Authentication headers, such as `Authorization` and `Content-Type`

{
  "title": "Sample PR Notification",
  "summary": "This is a sample PR notification",
  "sections": [
    {
      "title": "Changes",
      "facts": [
        {
          "name": "Repo",
          "value": "MyRepo"
        },

        }
      ]
    }
  ]
}

Step 3: Inspect the Azure DevOps and Teams logs

Test the API connection and notification using tools like Postman or cURL. This will help you isolate the issue:

curl -X POST \
  https://your-teams-channel-url.com/messages \
  -H 'Authorization: Bearer your-api-token' \
  -H 'Content-Type: application/json' \
  -d '{"title":"Sample PR Notification","summary":"This is a sample PR notification","sections":[{"title":"Changes","facts":[{"name":"Repo","value":"MyRepo"},{"name":"PR ID","value":"12345"}]}]}'
