Slack transcription integration

For teams who want the transcript to arrive where the conversation already is. The job: post the finished transcript, or a summary of it, into the channel that asked for it.

The one thing that breaks this

Slack requires a response to a slash command within 3 seconds. Acknowledge immediately, store the job_id, and post the transcript with response_url once your poller sees it finish.

Wiring it up

1 · Trigger

Any of these start the run:

2 · Submit from Incoming webhook, called from your poller once the job finishes

# submit — returns immediately, does not block
curl -X POST https://whipscribe.com/api/v1/transcribe/url \
  -H "X-API-Key: $KEY" \
  -H "Idempotency-Key: slack-$FILE_ID" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/recording.mp4",
       "diarize":true,
       "word_timestamps":true}'

→ 202 {"job_id":"a1b2…","status":"queued"}

# then poll — a self-serve (Pro) key collects by polling
curl "https://whipscribe.com/api/v1/jobs/$JOB" -H "X-API-Key: $KEY"
→ {"status":"processing"} … {"status":"done"}
Retry safety. Slack truncates long messages; post a snippet and attach the full transcript as a file.

3 · Collect

Submit, store the job id, and poll only the rows still queued.

# one job, every format — never re-submit per format
curl "https://whipscribe.com/api/v1/jobs/$JOB/result?format=txt" -H "X-API-Key: $KEY"
curl "https://whipscribe.com/api/v1/jobs/$JOB/result?format=srt" -H "X-API-Key: $KEY"
curl "https://whipscribe.com/api/v1/jobs/$JOB/result?format=vtt" -H "X-API-Key: $KEY"

Why run it here

No subscription to size wrongCompeting transcription tools sell $25–$65 monthly plans with a minute cap that resets whether you used it or not. Credits here are bought once and do not expire, so a quiet month costs nothing and a backlog run does not need an upgrade.
Your audio is not sent to a third-party modelTranscription runs on our own GPUs in our own private cloud. Nothing is forwarded to OpenAI or any other vendor's API, which is usually the blocking question when the recordings are customer calls or unreleased material.
One job, every formattxt, json, srt, vtt and docx all come from the same job id. Re-submitting a file per format is the most common way teams pay several times for one transcription.
Built to be retriedIdempotency-Key means an automation platform's automatic retry returns the original job instead of billing a second one. Every no-code platform retries; most transcription APIs charge you for it.

Try the quality free, then wire it up

Your first transcript in the web app is free, any length, no card — that is how to check accuracy on your own audio before writing any code. The API itself has no free tier: a key is self-serve once your account has credit ($50 minimum, spendable on transcription, and it does not expire). $8 per 1,000 minutes — about $0.48 an audio hour — and credits never expire.
