Chained microservice design pattern produce a single consolidated response to the request.
In this case, the request from the client is received by Service A, which is then communicating with Service B, which in turn may be communicating with Service C.
All the services are likely using a synchronous HTTP request/response messaging.

Think about the hypothetical scenario of money withdrawal at ATM’s.
You use your card at ATM (service A) which interacts with the Bank’s Server (Service B) which may call other service like balance check, transaction validation and so on (service N) and based on all these steps and based on the response ATM either allows the transaction or declines it.
