Guide to Fetching SMS Delivery Status Events via API in Node.js

The article argues that password-reset SMS templates and expiry rules should stay in the application, with delivery status events treated as untrusted reports handled at the integration edge. It recommends receiving or fetching events into an idempotent consumer, verifying their provenance, and normalizing only the needed fields while storing original payloads separately. A reset request should first create an application record that includes a non-secret identifier, template revision, and expiry timestamp, without logging the token itself. The author notes that delayed statuses should not trigger repeat reset attempts, and that application-owned templates trade operational convenience for reproducibility and release responsibility. A provider-neutral Python-style normalizer illustrates the internal event contract.
