Overview

This module leverages Azure DevOps REST APIs to compute key DORAMetrics.

​
Authentication & Permissions

  • Personal Access Token (PAT)

    • Must have Build (read) to query pipeline runs.
    • Code (read) for pull request and commit data.
    • Work Items (read) to fetch incident resolution dates.

  • Service Principal / OAuth

    • Grant equivalent scopes to access Builds, Git, and Work Items APIs.

Ensure the token or service connection is scoped to your organization and project for seamless data access.
