Representational state transfer (REST) is an architectural style designed as a request-response model that communicates over HTTP. ThingSpeak, an IoT platform, uses the REST API calls GET, POST, PUT, and DELETE to create and delete channels, read and write channel data, and clear the data in a channel. A web browser or client sends a request to the server, which responds with data in the requested format. Web browsers use this interface to retrieve web pages or to send data to remote servers.
You can also use REST API calls with Act on Data which let you interact with social media, web services, and devices.
