Integration practice
Plan the whole path, not just a successful request.
The integration guides cover document context, contact signals, minimization, and testing. Their common focus is a specific boundary: which component makes the observation, which policy interprets it, and which client action follows. Identify those responsibilities before selecting a provider or publishing operational promises.
Bring the guides into a review alongside the real service contract. Document authentication, coverage, versioning, data destinations, and failure behavior. The examples on this website are fixed fictional fixtures; they help discuss a design but do not replace the operational terms and methods of an actual provider.
Each guide includes a primary reference and links to related documentation. Use the articles as a review starting point, then align the recommendations with the actual methods, data, and policies of your implementation.
