Practical how-to articles published by APISeeker. Providers do not publish marketplace guides.
Step 1
Keep airline/status providers behind an internal FlightStatusPort so you can swap sources.
Step 2
Write status into your booking store with idempotent upserts keyed by flight + date.
Step 3
Separate customer notification rules from raw provider payloads.
Step 4
Protect keys on the server, meter per environment, and alert on 429/5xx spikes.
Step 5
Start on the marketplace to validate fit; renegotiate direct contracts only when volume justifies it.
