Defining API contracts and RESTful API design

In this section, we’re going to show how to define the API contracts for each microservice and follow the RESTful principles for designing your APIs.

Defining API contracts

API contracts microservices are the definitions of and agreements for how microservices communicate and interact with each other and external clients. An API contract specifies the format, structure, and rules of the data exchange between the service provider and the service consumer. Defining API contracts is a crucial step in designing microservices, ensuring clear communication and interoperability between different services. Here are its key components:

• Endpoints and routes: Clearly define the endpoints and routes for each service, specifying the URI paths through which different operations can be performed.
• HTTP methods: Specify the HTTP methods (GET, POST, PUT, DELETE, etc.) allowed for each endpoint. Define the purpose of each method and...
