n8n transcription integration

For engineers who self-host their automation layer and want the audio to stay on infrastructure they control. The job: run the whole pipeline on your own box: watch a folder, submit, poll for the result, post the transcript onward.

The one thing that breaks this

n8n will hold a Wait node for minutes, so a single workflow can submit and poll — but a Wait node pins a worker. On real volume, split it: submit in one workflow, poll on a Schedule Trigger in another.

Wiring it up

1 · Trigger

Any of these start the run:

2 · Submit from HTTP Request node

# submit — returns immediately, does not block
curl -X POST https://whipscribe.com/api/v1/transcribe/url \
  -H "X-API-Key: $KEY" \
  -H "Idempotency-Key: n8n-$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. Self-hosted n8n has no outbound egress limit, so it is the one platform where you can stream a multi-GB file through the automation itself.

3 · Collect

Poll from a Wait node, or move polling to a scheduled run once volume grows.

# 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.
