Service Requests

Requests could be executed inside a resource or rollback block. Requests interact with a external service through the configured transport protocol (ex: HTTP, gRPC).

The service method request and response object are used to define the request schemas. Responses produced by the given service could be referenced inside other resources of the given flow.

flow "CreateUser" {
    input "com.org.User" {}

    resource "user" {
        request "com.org.Users" "Create" {
          first_name = "{{ input:first_name }}"
          last_name = "{{ input:last_name }}"
          age = "{{ input:age }}"
        }

        rollback {
            request "com.org.Users" "Delete" {
              id = "{{ user:id }}"
            }
        }
    }

    output "com.org.User" {
        id = "{{ user:id }}"
        ref = "{{ input:ref }}"
    }
}
