Two-Way WhatsApp To Telegram Support Sync
Bridges WhatsApp customers to Telegram support agents by creating dedicated topic threads for each conversation.
founders and execsops and IT teams
What it does
You instantly organize every WhatsApp customer message into a dedicated Telegram thread so your support team manages thousands of chats efficiently. This bidirectional sync keeps you connected to customers on both platforms while eliminating the need for custom software development.
Step by step
- Configure n8n to listen for incoming webhooks from both WhatsApp and Telegram.
- Set up a Supabase table with columns for whatsapp_number, telegram_chat_id, and telegram_message_thread_id to maintain the mapping state.
- Implement HTTP request nodes in n8n to query Supabase for existing mappings before creating new ones or sending replies.
Where the LLM does the work
- Generate robust error handling logic for cases where a user switches devices or numbers, requiring dynamic re-mapping strategies.
- Design the message formatting rules to ensure rich text from WhatsApp renders correctly in Telegram threads without breaking layout.
- Create fallback workflows for when API rate limits are hit, deciding whether to queue messages or notify the support agent via email.
Watch out for
Telegram topics require a forum group type so ensure your target Telegram chat is configured as a forum before attempting to create threads.
Supabase row-level security can block reads if not configured correctly so verify the service key has full access to the mapping table.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Two-Way WhatsApp To Telegram Support Sync: Bridges WhatsApp customers to Telegram support agents by creating dedicated topic threads for each conversation. ## Specification - What it does: You instantly organize every WhatsApp customer message into a dedicated Telegram thread so your support team manages thousands of chats efficiently. This bidirectional sync keeps you connected to customers on both platforms while eliminating the need for custom software development. - Trigger: Triggered by an event (Event · on new message) - Autonomy: Fully hands-off - Expected setup effort: a few focused days - Tools/services involved: - n8n: Workflow orchestration and automation logic - WhatsApp Business Cloud API: Receiving and sending customer messages - Telegram Bot API: Managing support agent threads in supergroups - Supabase: Storing customer to topic mapping data ## Known pitfalls, handle each one explicitly in your implementation 1. Telegram topics require a forum group type so ensure your target Telegram chat is configured as a forum before attempting to create threads. 2. Supabase row-level security can block reads if not configured correctly so verify the service key has full access to the mapping table. ## Reference implementation https://n8n.io/workflows/8350 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Automation Platform than n8n?
Yes. n8n is only the example automation platform in this recipe. The same flow works with Home Assistant. Swap the automation platform connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for founders and execs who need customer support handled without hiring for it.
Ops-IT teams triaging their own internal requests get the same pattern, different queue.
