Description

To create an example following the new format to showcase how a service can be both a consumer and provider.

A hypothetical example within our standard user services:

sequenceDiagram
    participant User as User (Consumer)
    participant UserService as User Service (Consumer & Provider)
    participant AuthService as Auth Service (Provider)

    User->>UserService: Request to create account
    UserService->>AuthService: Validate credentials (Consumer)
    AuthService-->>UserService: Credentials valid/invalid
    UserService-->>User: Account created response

Motivation

It is quite common for a service to be both a consumer and provider, but the usual Pact examples really only show them as being one or the other.

Have you tried building it?

Self-service

• I'd be willing to contribute this feature to Pact Python myself.
