# Deepgram Webhooks & Callbacks ## Overview Implement async transcription with Deepgram's callback feature. When you pass a `callback` URL, Deepgram returns a `request_id` immediately, processes audio in the background, and POSTs results to your endpoint. Supports HTTP and WebSocket callbacks with automatic retry (10 attempts, 30s intervals). ## Deepgram Callback Flow ``` 1. Client -> POST /v1/listen?callback=https://you.com/webhook (with audio) 2. Deepgram -> 200 { request_id: "..." } (immediate) 3. Deepgram processes audio asynchronously 4. Deepgram -> POST https://you.com/webhook (results) Retries up to 10 times (30s delay) on non-2xx response ``` ## Instructions ### Step 1: Submit Async Transcription ```typescript import { createClient } from '@deepgram/sdk'; const deepgram = createClient(process.env.DEEPGRAM_API_KEY!); async function submitAsync(audioUrl: string, callbackUrl: string) { // Deepgram sends transcription via callback URL instead of // holding the connection open. const { result, error } = await deepgram.listen.prerecorded.transcribeUrl( { url: audioUrl }, { model: 'nova-3', smart_format: true, diarize: true, utterances: true, callback: callbackUrl, // Your HTTPS endpoint // callback_method: 'put', // Optional: use PUT instead of POST } ); if (error) throw new Error(`Submit failed: ${error.message}`); // Deepgram returns immediately with request...
