Duplicate webhooks, billed retries: the hidden costs of wiring a transcription API into an agent
Acrobatic-Farmer-109 · reddit · 2026-10-16
A developer building an agent that transcribes 45-90 minute sales calls and summarizes them into a CRM asks how to handle the handoff after transcription. They prefer webhooks over 30-second polling, but a test callback fired twice last week, producing duplicate summaries. Open questions: deduplicating callbacks, handling failed jobs and retries without reprocessing files, and why the cheapest per-minute rate is misleading when retries are also billed.
