Inwista n8n Workflow: Transcribe Media URL to SRT with Diarization

Transcribe any media URL into an SRT file—with speaker diarization—using n8n + Inwista

This Inwista n8n workflow takes a publicly reachable audio/video URL, submits it to the Inwista Transcriptions API with speaker diarization enabled, waits for the job to finish, and then downloads the resulting captions as an SRT subtitle file.

What this workflow does

Designed for manual execution inside n8n, the workflow:

• Runs when you manually execute it.
• Sets the media URL and a language code for transcription.
• Sends the source URL to the Inwista Transcriptions API to create a transcription job with diarization enabled.
• Waits 15 seconds, then checks the transcription job status via Inwista.
• Repeats status polling until the transcription is completed, or stops with an error if the job fails.
• Downloads the completed captions from Inwista as an SRT file.

Use cases

• Create subtitles from interviews, podcasts, or webinars stored at a media URL—no manual captioning.
• Generate speaker-labeled transcripts (diarization) for review, accessibility, or content repurposing.
• Integrate transcription into SaaS or internal tooling where media links are available programmatically.
• Automation engineers: standardize an Inwista-based “media URL → diarized SRT” pipeline in n8n.

Technical details

• API authentication via n8n HTTP Header Auth credential using: Authorization: Bearer <token>
• Nodes/blocks used: if, set, wait, sticky note, http request, stop and error
• HTTP Request steps handle: job submission, status polling, and SRT download

Setup tip: Replace the example mediaUrl (and optionally the language) with your publicly reachable audio/video URL, then attach your Inwista credentials to the relevant HTTP Request steps.
