I’m trying to run this example from the doc in the playground https://docs-next.graph.cool/reference/graphql-api/mutation-api-ol0yuoz6go#nested-mutations

mutation createAuthorAndContactDetails($contactDetails: AuthorcontactDetailsContactDetails) {
  createAuthor(
    description: "I am a good author!"
    contactDetails: $contactDetails
  ) {
    id
    contactDetails {
      id
    }
  }
}

what are some example of value for the variable

AuthorcontactDetailsContactDetails

@Miezan Go to https://www.graphqlbin.com, enter your API endpoint and at the right side of your screen you’ll see the bage

SCHEMA

. Click on it and then in the search field enter

AuthorcontactDetailsContactDetails

. You’ll see all the fields you should indicate as the payload to your mutation.

thanks!
