# Interactive walkthrough

This walkthrough replays the measured add-on use case. It shows the actual API requests and payloads from a Zuora test tenant, but it does not send any calls. Use it to see the sequence before you try the same steps in your sandbox.

For the written version of this use case, see [Measured add-on](/docs/get-started/tutorials/ai-monetization/measured-add-on).
