How Customer Support Teams Translate Call Notes Using APIs

Source: Dev.to

Overview

Customer support teams interact with users worldwide—one hour in English, the next in Spanish or Japanese. Managers need to read every call note, but manual transcription is impractical. Below is a clean API workflow that support teams are using in 2025 to automatically transcribe and translate calls.

4‑Step Workflow

1. Record or save the call – most tools already capture audio.
2. Send the audio file to Transgate API.
3. Receive transcription and translation in seconds.
4. Save the text into your CRM or helpdesk.

Step‑by‑Step Implementation

Step 1 – Get Your API Key

Navigate to Transgate → Dashboard → API Keys and copy the key.

Step 2 – Send Audio for Transcription

curl -X POST https://api.transgate.ai/v1/transcribe \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@/path/to/call_recording.mp3" \
  -F "language=en"

The response is JSON containing the full transcript with speaker labels.

Step 3 – Translate the Transcript

curl -X POST https://api.transgate.ai/v1/translate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "text=YOUR_TRANSCRIPT_HERE" \
  -F "target_language=es"

Step 4 – Save to Your System

You can pipe the result into automation tools (e.g., Zapier) or directly into platforms such as Zendesk, Freshdesk, etc.
