"Description": "Explore communication methods in ABP's microservice solution, covering synchronous and asynchronous patterns for seamless service interactions."

You must have an ABP Business or a higher license to be able to create a microservice solution.
Microservice solution template provides multiple ways to communicate between services, applications and API gateways. This documents explains the communication methods in the solution template.
In this pattern, a service calls an API that another service exposes, using a protocol such as HTTP or gRPC. This option is a synchronous messaging pattern because the caller waits for a response from the receiver.
In this pattern, a service sends message without waiting for a response, and one or more services process the message asynchronously. This is done by using a message broker or event bus. Further information check out.
