Field notes on AI-era growth, deliverability, voice, and messaging for developers and teams building on Orbit by Devotel.
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.
One POST per logical action, retried safely — how Orbit's Idempotency-Key contract, its 24-hour replay cache, the 409 body-mismatch guard, and wallet-level re-entry protection keep retries from becoming duplicate sends and double charges.
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.
