Convert Supabase support FAQs to audio with Google Cloud TTS and Webflow

Enhance your support documentation with an audio-first experience. This workflow converts Supabase FAQ entries into high-quality audio using Google Cloud TTS, hosts them via a CDN, and embeds them into your Webflow support pages.


🎯 What This Workflow Does

This template transforms static FAQ content into a professional audio library through a multi-stage process.


πŸ”” Step 1 β€” Webhook Intake & Intelligent Fetch

  • Webhook Trigger: Processes specific FAQ IDs or categories on demand
  • Supabase Query: Fetches unprocessed or requested FAQ records

πŸ“‹ Step 2 β€” Data Enrichment & SSML Preparation

  • Deduplication: Ensures each FAQ is processed only once
  • SSML Formatting: Adds pauses and emphasis for natural speech delivery

πŸ—£οΈ Step 3 β€” Google Cloud TTS & Hosting

  • Audio Generation: Converts text to MP3 using Google Cloud TTS (WaveNet)
  • CDN Hosting: Uploads audio via UploadToURL to generate a public URL

🌐 Step 4 β€” CMS Update & Database Write-Back

  • Webflow Update: Inserts audio URL into FAQ pages for playback
  • Supabase Update: Marks records as published with timestamps

πŸ’Ό Step 5 β€” Reporting & Confirmations

  • Microsoft Teams Alert: Sends summary with audio links
  • Webhook Response: Returns JSON confirmation to trigger source

✨ Key Features

  • Accessibility First: Enables audio-based support consumption
  • SSML Intelligence: Improves clarity with structured speech formatting
  • Rate-Limit Safe: Processes items sequentially to avoid API limits
  • Reliable Hosting: UploadToURL ensures stable public audio URLs

πŸ”§ Setup Requirements
