Examples

Simple

The below example retrieves a pet with number '1234' from the swagger petstore:

{
  "id": "rest_activity",
  "name": "REST Activity",
  "activity": {
    "ref": "github.com/project-flogo/contrib/activity/rest",
    "settings": {
      "method": "GET",
      "uri": "http://petstore.swagger.io/v2/pet/1234"
    }
  }
}

Using Path Params

The below example is the same as above, it retrieves a pet with number '1234' from the swagger petstore, but uses a URI parameter to configure the ID:

{
  "id": "rest_activity",
  "name": "REST Activity",
  "activity": {
    "ref": "github.com/project-flogo/contrib/activity/rest",
    "settings": {
      "method": "GET",
      "uri": "http://petstore.swagger.io/v2/pet/:id"
    },
    "input": {
      "params": { "id": "1234"}
    }
  }
}
