While JSON may be human-readable, it is not optimal when used between services. Given this request, our response (irrelevant headers omitted) may look like: HTTP/1.1 200 OK Here, we request a product resource with an ID of 11 and direct the API to respond in JSON format: GET /products/11 HTTP/1.1 To illustrate, let’s look at a simplified example of retrieving a product via a REST API. Request and response bodies contain data that is specific to the operation, while their headers provide metadata. A REST API is generally built on the HTTP protocol, using a URI to select a resource and an HTTP verb (e.g., GET, PUT, POST) to select the desired operation. Representational state transfer (REST) is a means of retrieving or manipulating a service’s data. While REST is a favored approach, gRPC is a worthy contender, offering high performance, typed contracts, and excellent tooling. Many standard technologies address the interservice communication needs of distributed systems, such as REST, SOAP, GraphQL, or gRPC. APIs bridge communication between services that may represent a single, complex system but may also reside on separate machines or use multiple, incompatible networks or languages. In today’s technology landscape, most projects require the use of APIs.
