---
An explorer that sends requests needs a credential in the page and an origin to point at. Both are
mistakes: the credential ends up in browser history and logs, and the origin becomes a default
someone points production traffic at.

So this explorer renders the contract and hands you a command. You choose the origin and supply
the credential in your own environment.

## Reading a mutation

Mutations are marked. Before building one, read:

- [Authentication](/develop/authentication/) for the signature material and headers.
- [Idempotency and request IDs](/develop/idempotency-and-request-ids/) for safe retries.
- [Marketplace v1](/reference/api/marketplace-v1/) for the exact protocol data shapes.

The copied command carries placeholders for the idempotency key and the body, because the
signature covers the exact body bytes. Re-serialising the body invalidates it.
