I see that “clientMutationId” is always needed as part of the GraphQL payload. But What is this for??

In the result from GraphQL always come back as NULL. In the Dev Docs says “A unique identifier for the client performing the mutation.” Can I register a Client for the miutation?

 

Thanks!

Hello Reicado.. So any string I put in this field will be reflected as the name of the “person” making the mutation?

Hey Ramon! You can think of this as more of an identifier in case you need to debug which of the queries went wrong. Together with whatever language you prefer to script in, you can make it dynamic and you’ll have improved your logs;
