Hey all! 
Michelle here from the Apollo Education team. I’m a Developer Educator and I build courses for Odyssey, our official learning platform.
I’m back for the next edition of a multi-part series to teach you the basics of Apollo Connectors: a powerful way to bring existing REST APIs into your graph, all through configuration in the schema.
This week’s learning: Debug and discover Connectors in Sandbox
Apollo Sandbox is a playground that lets us explore our GraphQL API, building and sending queries easily. It also gives us a full view into how our Connectors work.
For every request a Connector makes, we can dig into the details of the request, the response, and the mapping that transforms that response into the data our schema expects.
You might not get your selection mapping right the first time around, so make sure to check out the Mapping tab for any errors and hints on how to fix it!
Want to go deeper?
Explore a pre-built example with Connectors and the Stripe Payments API using the embedded Sandbox.
You can also see how to use the Debugger to investigate mapping errors in the Odyssey tutorial “GraphQL meets REST with Apollo Connectors” (Lesson 6).

Have you used any of the tools we’ve shared above? What other tools might be helpful for you as you try out connectors?
