str
Optional. A unique request ID (optional). If
you specify this ID, you can use it in cases
when you need to retry your request. When you
need to retry, this ID lets the server know that
it can ignore the request if it has already been
completed. The server guarantees that for at
least 60 minutes after the first request.
For example, consider a situation where you make
an initial request and the request times out. If
you make the request again with the same request
ID, the server can check to see whether the
original operation was received. If it was, the
server ignores the second request. This behavior
prevents clients from mistakenly creating
duplicate commitments.
The request ID must be a valid UUID, with the
exception that zero UUID is not supported
(00000000-0000-0000-0000-000000000000).
