Yes, it is true.
An API call will be received by the gateway and will route it to the appropriate microservice.
Whenever we think of microservices and distributed applications , the first point that comes to our mind is security.
In distributed architectures, it is very difficult to manage security. In this situation you need to have a central entry point.
This is the reason, why in microservices, we have a separate and dedicated layer for all these purposes.
This layer is known as API Gateway.

‘An API call will be received by the gateway and will route it to the appropriate microservice’ is a TRUE statement.
Explanation:
- API gateway is actually a server which is a single entry point into the system. It is same as Façade pattern from the design of object-oriented design.
- It encapsulates internal system of architecture and delivers an API which can be tailored to every client.
- It has several other responsibilities like authentication, load balancing, monitoring, request shaping, caching and management.
- All the requests from the clients will go through API gateway and then these requested are routed to appropriate microservice.
