Ah cool, thanks. Okay, so that basically gives you GraphiQL from within your store admin to explore the API. But it is just that, for exploring.
But to use any of those GraphQL queries and their results, you will need a server application that has access to the endpoints using the key and pwd you setup in your private app or app. Unless you're using Storefront API where you can access via key alone and use a browser based GraphQL client library.
Hope this helps (or adds to the confusion :D )
David, although GraphiQL can be used in the way you described (querying for data as a store owner) it is, like Karl mentioned, just for exploring the API and should not be seen as a data mining / exporting tool.
If you would like to use the API properly (without writing applications) you will have to:
1) get authentication credentials (investigate Private Apps)
2) Use some flavor of an API Dev Environment (ie: Postman) to make your API requests using the relevant endpoints. (investigate API authentication headers)
This will always return results in JSON format. If you require the data in any other format, you will need to do additional processing yourself. This is best accomplished by building / having an app built to suit your requirements. Working with pure JSON as a store owner is messy and I would strongly advise you to approach an app developer instead.
We just set up a store ....
even though this is the api subforum, that seems conflit with the opening post
I added the GraphiQL app to my store but don't see how to export the result of a query. How is this done ....
So sidestepping graphql for a moment, what data are you trying to get and why? what are you trying to accomplish
