As nowadays those APIs is serving many channels either it is Mobile, Microservices components, IoT, integration or all of them. This session will help you plan and model your own APIs and understand the six REST design constraints that help guide your architecture. I will start with a simple overview, including advice on identifying the users or "participants" of your system and the activities they might perform with it.
