str
Optional. A request ID to identify requests.
Specify a unique request ID so that if you must
retry your request, the server knows to ignore
the request if it has already been completed.
The server guarantees that a request doesn't
result in creation of duplicate commitments for
at least 60 minutes.
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).
