Calling external GraphQL/REST service with postgrahile
I'm considering using postgraphile for a new project. However, I need to use some of the fields in the GraphQL responses to make a call to an external API before returning the original data along (augmented) with the data from the API.

The data returned does not need to be stored but just included as additional fields. 

The external service exposes both a REST and GraphQL service. 

Is there a way to do this ?
