In microservices architecture, the following methods are commonly used for interaction between services:

• HTTP/REST API — the most common way, where services communicate via the HTTP protocol, exchanging data in JSON or XML format.
• gRPC — a high-performance remote procedure call protocol that uses HTTP/2 and binary serialization, suitable for internal communications.
• Messages via brokers (Message Brokers) — asynchronous interaction through queue systems like RabbitMQ, Kafka, which increases reliability and scalability.
• Event-driven architecture — services exchange events and react to changes in the state of other services.

Example of a simple HTTP request in Go to call another microservice:

resp, err := http.Get("http://serviceB/api/resource")
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()
body, _ := ioutil.ReadAll(resp.Body)
fmt.Println(string(body))
