Other improvements include clarifications and enhancements to specifications and documentation, improved integration among all the MicroProfile APIs, interoperability across different MicroProfile implementations, and a complete set of artifacts for each API.
Based on JSR 339 for consistency and easier reuse, the MicroProfile Rest Client API provides a type-safe approach to invoke RESTful services over HTTP that handles the communication between a client and a service. Rest Client makes the HTTP connection and serializes an object so that a remote service can process it.
