Prepare for the Claude Certified Developer – Foundations exam, on the exam guide version 1.0, effective July 2026. In this lesson: HTTP methods, status codes, and idempotency keys, strict JSON, async requests within rate limits, Git, pull requests, and CI with Claude Code (GitHub Actions, claude -p), and refactoring with tests. Includes three original practice questions.
Preview the topics
- Driftwood’s script sent a POST request to create a dispute, timed out, retried, and created the same dispute twice. What prevents this?
- Driftwood wants every pull request checked for security vulnerabilities before a person reviews it. Which approach fits?
- Driftwood asks Claude Code to move 400 files to a new logging API in one long session, and halfway through, the context is full and the edits drift. What works better?
