Connect WhatsApp to ChatGPT

What you need

• WhatsApp on your phone, with the number you want ChatGPT to use.
• A WaBot API key. Start a free trial: 3 days, no card.
• A ChatGPT plan that supports custom connectors. Menu names can vary slightly between plans.

Step 1: Get your key and link your WhatsApp

1. 1 On the WaBot home page, choose Start free trial and enter your email. Confirm it, and your API key arrives in your inbox.
2. 2 Open the portal link from that email and go to Connect Device.
3. 3 On your phone, open WhatsApp → Linked devices → Link a device, and scan the QR code.

Step 2: Add WaBot to ChatGPT

1. 1 In ChatGPT, open Settings → Apps & Connectors. If you don't see a Create button, turn on Developer mode under Advanced settings.
2. 2 Click Create, name it "WaBot", paste the URL https://wabot.astranexo.com/mcp and choose OAuth as the authentication.
3. 3 Confirm that you trust the app and click Create. A WaBot page opens: paste your API key (or click Continue as if you're signed in to the WaBot portal in the same browser), then click Allow.
4. 4 In a chat, pick WaBot from the tools / connectors menu and ask for what you need.

Things to ask ChatGPT

What ChatGPT can do, and the limits

• See whether your WhatsApp is connected and how many messages you can still send today.
• List your recent chats, read a conversation, and find people and groups by name or number.
• Send messages and files, but only to people and groups you've already written to: never new numbers, or chats only the other person started.
• ChatGPT asks for your OK before each message it sends, and messages go out a few seconds apart to protect your number.
• WaBot doesn't store your chats: ChatGPT reads them live when you ask.

Which plan do I need?

Every plan works with ChatGPT. To have ChatGPT reply to other people, choose Unlimited ($6/month or $60/year). Personal ($1/month or $10/year) only sends to your own number. Compare plans.

Disconnecting

Remove the WaBot connector in ChatGPT's settings. To disconnect every assistant at once, get a new API key in the WaBot portal (your other integrations will then need the new key).

Using Claude too? The same WaBot account works there: see Connect WhatsApp to Claude.
