Field notes on AI-era growth, deliverability, voice, and messaging for developers and teams building on Orbit by Devotel.
Rate limiting is a contractual quota; throttling is the platform's dynamic pressure valve. Developers conflate the two and misdiagnose 429s — a definition guide for messaging APIs on Devotel Orbit.
Rate limiting and throttling are two halves of the same protection mechanism in CPaaS APIs. This explainer defines both terms, walks a worked 429 with backoff and jitter, and shows how idempotency keys keep retries safe.
Throttling is the deliberate pacing of outbound message traffic so sends stay within carrier and platform throughput limits. This explainer covers what it is, why messaging APIs throttle, and how to design retries that survive it.
Definitions of rate limiting and throttling for API builders: what each mechanism controls, how 429 responses and Retry-After headers work, and how to design retries that keep messaging deliverable.
Rate limiting caps request volume with quota rejections; throttling shapes traffic by delaying it. This explainer separates the two and gives a practical checklist for building around both in CPaaS integrations.
