Connect ChatGPT to WhatsApp.
Let ChatGPT read your WhatsApp inbox, draft replies and trigger automations — straight from your conversation with the assistant. Works with ChatGPT, Custom GPTs, the OpenAI desktop app and any MCP-aware tool. Set up in 5 minutes. No code, no install.
ChatGPT talks to your inbox. In three steps.
Once you've added Wassenger as a custom MCP app in ChatGPT (Settings → Apps → Advanced settings, enable Developer mode, then Create app — five minutes), ChatGPT can read your WhatsApp inbox, find contacts, draft and send replies, and trigger your automations — all from a normal conversation. No code. You stay in control: ChatGPT asks before sending anything.
You connect ChatGPT once
Open ChatGPT → Settings → Apps → Advanced settings, enable Developer mode, then Create app. Paste your Wassenger MCP URL and API key, then connect. Five minutes, one time. Claude Desktop, Cursor and other AI assistants have similar flows (only the menu differs).
You ask ChatGPT in plain English
“Show me unread WhatsApp leads from this morning.” “Draft a reply for Alex.” “Summarise yesterday's support tickets.” Whatever you can describe, ChatGPT can do.
ChatGPT does the work, you approve
ChatGPT shows you what it's about to do — and waits for your OK. Nothing happens on your WhatsApp without your green light. Full transparency, zero surprises.
What ChatGPT can do, once connected.
Four simple skills cover most day-to-day inbox work. You ask in plain English — ChatGPT picks the right one.
Read your unread chats
ChatGPT can list the latest unread conversations — who sent them, the last message and when — filtered by label, agent or channel.
Send a reply
ChatGPT drafts and sends messages — text, media, buttons or pre-approved templates. You can require a confirmation before anything goes out.
Find a contact
Look up anyone by name, phone, label or custom field. ChatGPT pulls the profile and recent chat history, perfect for "find the customer who…" questions.
Trigger an automation
Run a Flow you already built — welcome sequences, lead qualification, handoffs, reminders. ChatGPT can fire them on demand or on a schedule.
Live in 5 minutes.
Three clicks to read your first WhatsApp message from ChatGPT. No installs, no code, no technical setup.

Open ChatGPT, go to Settings → Apps → Advanced settings, enable Developer mode, then under Apps click Create app. Paste your Wassenger MCP URL and API key — no code, no install required.
Talk to your inbox
Once the custom MCP is connected, open any ChatGPT conversation and ask: "show my unread WhatsApp leads", "reply to Maria with the proposal" or "schedule a follow-up tomorrow." ChatGPT asks before sending anything.
"Show me my unread WhatsApp leads from this morning"Using Claude, Cursor, Windsurf or a different AI tool? Same idea — only the menu changes. See guides for every AI assistant →
