SmartChat API and MCP: connect your system.
With the SmartChat API you connect your own system to SmartChat, and since 17 September 2026 Claude, ChatGPT and other AI apps handle your WhatsApp marketing via MCP.
Two ways in SmartChat.
The API is for your own software, MCP is for your AI app. Both follow the same rules as the app.
API for your system
- Your shop, your till or your booking software talks directly to SmartChat.
- Each program gets its own API key.
- It takes a few lines of code.
MCP for your AI app
- Claude, ChatGPT or another AI app runs SmartChat in plain sentences.
- You sign in with your SmartChat account and allow the permissions.
- You don't need any code for this.
Your AI app connected in four steps.
No key and no code: all you need is the address from SmartChat and your account.

Start writing
From now on, you tell your AI app in plain sentences what it should do in SmartChat.
You to Claude: Schedule the hut tour newsletter for Friday at 9 a.m.
Schedule newsletters with one message.
Ask your AI app for a newsletter, and SmartChat AI writes the draft. You give the date in the same chat, and SmartChat then starts sending automatically.
Draft from SmartChat AI
Header, text and button are created just like in the AI Chat.
Scheduling by message
A sentence like "Friday at 9 a.m." is enough to schedule it.
Only after your OK
Before sending, SmartChat shows the number of recipients and waits for your confirmation.
A separate key for each program.
In Settings under Integrations, you create an API key for each program. For each one, you see what it's allowed to do and when it was last used.
Read only or write too
For each key, you choose whether it can only read or also write.
Blocked instantly
If a key falls into the wrong hands, you delete or renew it with one click.

All the steps are in the API quickstart.
New contacts arrive on their own.
When your program creates a contact via the API, it shows up alongside all your other contacts in SmartChat. It only gets messages once it has agreed.
