# Sandbox and live

[Intro](#intro)

<h2 id="intro">
  Intro
</h2>

The product names environments `sandbox` and `live`. Every client must send the environment explicitly. A missing profile never chooses live.

OpenAPI servers list sandbox first. Try It and docs examples use sandbox only.

Next: [auth](./auth#intro) and [errors](./errors#intro).

`operation_id` values are identical in both environments. Money, ledger, and secrets never cross the boundary.
