Greengrass V1 API

AWS IoT Greengrass provides a resource-based API that uses Hypertext Application Language (HAL). HAL provides a standard way for expressing the resources and relationships of an API as hyperlinks. Using HAL, you use HTTP methods (GET, PUT, POST, DELETE) to submit requests and receive information about the API in the response. Applications can use the information returned to explore the functionality of the API. For more information about HAL, see the JSON Hypertext Application Language draft.

To request a HAL response from AWS IoT Greengrass, specify application/hal+json for the accept request header.
