Lesson 3 of 10 · AI API Integration Masterclass
In this lesson. Verify signatures; make handlers idempotent.
What you will learn
- Signatures
- Upsert
- Out-of-order
Walkthrough
You will verify, then upsert. Out-of-order is normal. This is production integration, not a tutorial happy path.
Work through the ideas in order. After each point, pause and connect it to a task you already do — a document, a workflow, or a feature you own. The goal of AI API Integration Masterclass is usable skill, not a pile of notes.
If something is unclear, rewrite it in your own words before you continue. Teaching the step back to yourself is the fastest way to see gaps.
Practice
Write the webhook handler rules in five bullets.
Keep the first attempt small. A finished example you can reuse beats a perfect plan you never run.
