Blueticks
Log in
WhatsApp connector for ChatGPT

Connect WhatsApp to ChatGPT on your own number.

Add one URL as a custom MCP server in ChatGPT and sign in to Blueticks. ChatGPT can then read your chats and draft replies. Whether it can also send depends on your ChatGPT plan. The connector is hosted, so there is no server for you to run. This is ChatGPT working on your own chats, not the ChatGPT contact inside WhatsApp.

MCP server URL
https://api.blueticks.co/mcp

Works on any Blueticks plan; the free plan is limited to 5 requests per 6 hours. Which ChatGPT plans can add custom MCP servers is OpenAI's rule: see OpenAI's help article.

Link your WhatsApp

ChatGPT reads a chat, then schedules a follow-up

A short staged demo. The ChatGPT screen is recreated for the video and the chat is a test number.

How to connect ChatGPT

Menu names move as ChatGPT updates, so match on meaning.

First: link WhatsApp

Open app.blueticks.co/connections, sign in and link your number by QR code or phone-number link code. Use the browser extension with WhatsApp Web open, or add a Gateway for a cloud-hosted, always-on connection. Without it, every request from ChatGPT fails with a "No WhatsApp is connected" error.

Then: add the server in ChatGPT

  1. On the web, open chatgpt.com/plugins, select +, then Add custom MCP server.
  2. Enter https://api.blueticks.co/mcp as the URL and set authentication to OAuth.
  3. Accept the custom-server warning, choose Create as a plugin, sign in to Blueticks and approve.
  4. Start a new conversation and turn Blueticks on with @ or the + menu.

Sign-in is OAuth 2.0 with S256 PKCE, so no API key is stored in ChatGPT. Plan limits apply on OpenAI's side. Full walkthrough: connect WhatsApp to ChatGPT.

A first prompt: drafts only, nothing sent

Turn Blueticks on in a new conversation and paste this. The last two sentences keep it to drafts, because where your plan allows it the connector can send from your number. You read, edit and send each reply yourself.

Using Blueticks: list my one-to-one WhatsApp chats active in the last 7 days
where the last message is from the other person. Read the recent messages of
the top 10 in one batch. For each, write a short draft reply in my voice, with
the contact name above it. Do not send or schedule anything. I will send these
myself.

The server has twelve tools; ChatGPT shows one per action. Tool list checked 10 November 2026 against api.blueticks.co/mcp/info: twelve tools on the MCP page. Approve each call yourself and avoid "Allow always" for Blueticks.

How it connects to WhatsApp

Blueticks operates an unofficial WhatsApp Web automation engine: your number is linked as a device. It is not the Meta Cloud API, and Blueticks is not affiliated with or endorsed by WhatsApp, Meta or OpenAI. We cannot promise a number will never be restricted. If you message other people, consent and opt-out are your responsibility.

Frequently asked questions

How do I connect WhatsApp to ChatGPT?

Link your WhatsApp number in Blueticks. Then, in ChatGPT on the web, open chatgpt.com/plugins, select +, choose Add custom MCP server, enter https://api.blueticks.co/mcp as the URL and set authentication to OAuth. Accept the custom-server warning, choose Create as a plugin, sign in to Blueticks and approve. Start a new conversation and turn Blueticks on with @ or the + menu.

Which ChatGPT plans can use it?

That is OpenAI's rule, not ours, and it changes, so check OpenAI's help article on developer mode and MCP apps before you start. Plan limits apply on OpenAI's side.

Do I need an API key or to run a server?

No. The remote connector signs in with OAuth 2.0 (authorization code, S256 PKCE), so no API key is stored in ChatGPT and you run no server of your own. Blueticks hosts the connector; the WhatsApp session runs in your browser (extension) or in a Gateway.

Does it use my own WhatsApp number?

Yes. You link your number as a WhatsApp Web linked device by scanning a QR code or using a phone-number link code. It is not the Meta Cloud API and not an official Meta product. It is also not the ChatGPT contact inside WhatsApp: ChatGPT works on your own chats from the ChatGPT side.

Can ChatGPT send messages, or only read?

Whether ChatGPT can send depends on your ChatGPT plan under OpenAI's rules (see OpenAI's help article). Where it can, the connector can send and schedule from your number, so approve each call yourself and avoid "Allow always" for Blueticks. If you only want drafts, say so in the prompt, as in the example above, and send them yourself.

Which tools does ChatGPT see?

The server has twelve tools covering chats, contacts, groups, scheduled messages, audiences, campaigns, webhooks, tasks, engine and utilities. ChatGPT shows one tool per action instead of one per group of actions. The full list is on the MCP page.

What does it cost?

There is no extra charge for the connector and it works on any Blueticks plan. The free plan allows 5 requests per 6 hours, shared with the API; paid plans have no request limit. See the pricing page for current prices.

Why does ChatGPT say no WhatsApp is connected?

If no WhatsApp is linked to your Blueticks account, or the connection is offline, requests fail with a "No WhatsApp is connected" error. Link it at app.blueticks.co/connections, keep WhatsApp Web open with the extension on, or use a Gateway for an always-on connection.

Is there a ban risk?

Blueticks connects through the WhatsApp Web linked-device model. We cannot promise that WhatsApp will never restrict a number. Consent and opt-out for anyone you message are your responsibility.
