To Consume a REST Service (Design Center)
You can design an app to consume a REST service by setting up HTTP Listener and Request operations. In this procedure, you first consume a REST API service. Next, you test the HTTP request. You edit the Request configuration to make a secure HTTPS request. Finally, you test the HTTPS Request.
-
In a new project, set up the HTTP Listener for a message from the browser to start this app: Use the default CloudHub HTTP configuration and set Path to /trigger.
-
Click + to add another component to the flow, and select HTTP Request.
