Application and Integration Architecture

Document your application portfolio, service interactions, and integration patterns. This area covers how systems connect and communicate.

The Application and Integration Architecture directory is where you document your software systems, their components, and how they interact with each other and external services.

What Belongs Here

This directory is the home for documentation about your application landscape and the connections between systems:

Recommended Content Blocks

When documenting application and integration architecture, these content blocks are particularly useful:

Diagram Types

Several diagram styles are well-suited to application and integration documentation:

API Documentation

Document REST APIs with full endpoint specifications, OpenAPI import and export, seven HTTP methods, parameters, request and response bodies linked to shared schemas, authentication schemes, and a published API browser. REST is one of six API types (REST, GraphQL, gRPC, AsyncAPI, Webhooks, MCP) sharing a unified schema layer.
