Access to the clientMutationId provided to a mutation #81
Description
Is your feature request related to a problem? Please describe.
I want my API to cache mutation responses against a clientMutationId.
Describe the solution you'd like
I want access to the clientMutationId provided to a mutation so that if my API sees the same clientMutationId twice, it can be certain it is a duplicate call, and return the cached value.
Perhaps exposed via a ClientMutationId parameter decorator.
