4. Defining a @source
2m

Practice

The @source directive
The @source directive takes in a few parameters to help us define a shared data source for multiple Connectors. The name parameter is a 
 
 for the data source. The 
 
 parameter defines the REST API endpoint we want to connect to. We can also set headers that we want to pass to the REST API using the 
 
 parameter.

Drag items from this box to the blanks above

  • headers

  • http.headers

  • Connector

  • http.restHeaders

  • unique identifier

  • http.restAPI

  • http.baseURL

Code Challenge!

Define a @source named outerspace that points to the URL http://outerspace-api.example/. Include a header named x-caller with a hard-coded value of space-schema. Review the previous lesson for a refresher on the @source parameters and how to include headers.

Key takeaways

  • The @source defines a shared data source for multiple Connectors.
  • The @source takes in two parameters: name and http.

There's one thing we're missing from our schema: the endpoint we should connect to. Let's fix this build error in the next lesson!
