How to get the associated changes, check-in comments and linked work items for a particular build/release in VSTS

Question

I am using SendGrid email extension to trigger a custom email notification after the CI/CD process is complete in VSTS. This email task has HTML content in it which includes some content fetched using standard build/release variables (https://learn.microsoft.com/en-us/vsts/build-release/concepts/definitions/build/variables?tabs=batch).

How do I include associated code changes, check-in comments and linked work items for a particular release in the custom email? Are there any variables I can use? Any work around?

Answer 1

There aren’t the built-in variables that can get code changes, check-in comments and linked work items.

You can get them through REST API during build or release:

1. Get build changes and work items through Get Build Changes REST API (Build id variable: Build.BuildId during build or Release.Artifacts.{Artifact alias}.BuildId during release) Note: using Build.SourceVersion to get latest version)
2. Git: Get commit message through Get a batch of commits by a list of commit IDs REST API
3. TFVC: Get check-in comment through Get list of changesets by a list of IDS REST API
4. To get changed items, you can use get commit with changed items or Get list of changes in a changeset REST API.

No API to get detail code changes, but you may refer to this related issue: Lines of Code modified in each Commit in TFS rest api. How do i get?
