Tutorial on ABAP HTTP Client REST Service Calls (using Polestar OnDemand)
In this eLearning we will look at the configuration and coding steps necessary to call REST based web services from ABAP. In particular we will look at the extra steps necessary for working with REST based services over HTTPS. For the example we will be consuming the REST based services of Polestar OnDemand. But even if you aren't interest in working with Polestar OnDemand, you can still learn about HTTPS certificates, proxy settings in the ICM, HTTP destination setup and coding against the CL_HTTP_CLIENT ABAP class.
