GraphQL interpolation between query sections.

[3goats]

Apologies for raising this question here, but I'm new to GraphQL/Hasura and don't know if I'm barking up the wrong tree.

I have a graphQL query that essentially queries two datasources. I need to pass some data returned from the first part of the query to the second part. i.e. Pass the returned hostname from the config query to the CommonName in the GetCertificate query. e.g.

query get_config {
  config {
    id
    hostname
  }
  getCertificate(
      CommonName:  $hostname) {
    Certificate
    Key
  }
  }

So basically perform a single query but pass in some of the output from the first part of the query to the second part.

I have also asked the question here on Stack-overflow however, I'm not sure if its possible to implement within Hasura.

What are the two data sources? i.e. where is config retrieved from and where is getCertificate?

If getCertificate is from a remote schema, then a remote schema relationship would be the right way to go: https://hasura.io/docs/latest/graphql/core/databases/postgres/schema/remote-relationships/remote-schema-relationships.html#remote-schema-relationships
