Steps
Call the Asynchronous Speech-to-Text API at base URL https://api.rev.ai/speechtotext/v1 with your access token and a source audio file or URL
Register a webhook/notification URL on the job rather than polling, since Rev.ai explicitly discourages polling in production
Wait for the webhook callback indicating the job has completed
Retrieve the transcript, and pull captions in SRT or VTT format from the same completed job if caption output is needed
Track usage against the documented default rate limits (10,000 submissions and 500 processed transcriptions per 10 minutes) to avoid throttling
Known gotchas
Polling the job-status endpoint repeatedly is explicitly discouraged for production use - use webhooks instead or you risk hitting rate limits under load
Caption formats (SRT/VTT) are retrieved from the completed transcription job, not from a separate captions-only submission endpoint
