Our Patterns for API Design, also known as Microservice API Patterns (MAP), capture proven solutions to problems commonly encountered when specifying, implementing and maintaining message-based APIs. MAP focusses on message representations – the payloads exchanged when APIs are called. These payloads vary in their structure as API endpoints and their operations have different architectural responsibilities. The chosen representation structures strongly influence the design time and runtime qualities of an API. The evolution of API specifications and their implementations has to be governed.
