Definition

An idempotency key is a unique token sent with a write request so that retrying the request does not repeat the change.

How to use it

If a request times out you cannot tell whether it went through. Sending it again with the same key lets the server recognise it and do the work once, which matters when a retry could create a second ad or double a budget.
