Questions

What can the AI do in iClosed?

It can search and read contacts, contact stages, notes, booked calls, deals, event types, products, transactions, users, availability and custom fields. It can create and update contacts, add notes, reschedule and cancel calls, record call outcomes, create and update deals, create products, record and update transactions, and set custom field values.

Does the AI see my iClosed API key?

No. Your iClosed API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with lookups only. Cancelling a call cannot be undone, and rescheduling moves a real appointment, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own iClosed account.

Does recording a transaction charge the customer?

No. record_transaction only logs the transaction in iClosed with its value and details. No money is charged. You can then link the transaction to a deal with update_deal.
