Frequently asked questions about ChatGPT and SmartChat.
How do I connect ChatGPT with SmartChat?
In ChatGPT in the browser, you create your own MCP server, give it a name and enter the address of the SmartChat MCP server. For sign-in you choose OAuth. Then you log in to SmartChat and choose the permissions on the consent page.
What is behind the MCP server?
It's the connection that lets an AI assistant like ChatGPT operate SmartChat. It builds on the SmartChat API. You can find out more on the page MCP server.
What permissions does ChatGPT get?
The ones you choose on the consent page. Everything the app can do is allowed, except deleting and plan actions like upgrade, downgrade or cancellation. Both stay blocked.
Does ChatGPT ask before it changes something?
According to OpenAI's guide, write actions require a confirmation by default. You see the inputs and approve them. In the access settings, individual tools can be switched on or off.
What do I use ChatGPT with SmartChat for?
For flows that then run on their own: a welcome the day after sign-up, a message to quiet contacts or a reply to a keyword. The automations themselves then send via WhatsApp.
Are there limits for the access?
No separate limits are planned for API and MCP. What your plan allows is not affected, for example the number of automations.
How many automations are allowed?
Free and Starter only have the fixed automation for new contacts. Basic has 3 automations, one of them fixed. Pro has unlimited.
What does the connection cost?
The plans cost โฌ0 for Free and โฌ299, โฌ499 or โฌ999 per month for Starter, Basic and Pro, each plus VAT. Sending and every run of an automation need no credits. Meta charges its own fees, and the prices are listed here.
How do the messages reach my contacts?
Whatever goes out beyond the inbox is a template approved by Meta. SmartChat AI writes this template and submits it. Only after that does the automation run.
What happens when someone writes STOP?
Then SmartChat unsubscribes the contact right away. They get no more newsletters and no more automations.
Where do I see what my contacts reply?
In the inbox of SmartChat. There you read every reply and continue the conversation.
