@baseUrl = https://api.example.com
@resourceId = replace-with-id-from-create-response

### Create a resource
POST {{baseUrl}}/widgets
Accept: application/json
Content-Type: application/json

{
  "name": "Sample widget"
}

### Fetch it after manually copying the returned ID into resourceId
GET {{baseUrl}}/widgets/{{resourceId}}
Accept: application/json

Variables to replace

baseUrl
The API origin.
resourceId
The ID copied from the create response before running the GET request.

Expected response

Create commonly returns 201 Created with the resource ID in JSON or a Location header. Copy that ID into resourceId; the second request should then return 200 OK.

Karve does not perform response chaining, so it will not populate resourceId from the POST response automatically.
