Connect Claude & ChatGPT to Fintoc

Ask your AI which payments came in this week, what moved on a treasury account or whether a dispute needs documents in Fintoc. It can create customers, payment links, checkout sessions and invoices in Chilean or Mexican pesos, finalize invoices, and cancel payment links or subscriptions, with your approval if you want it.

Questions

What can the AI do in Fintoc?

The AI can read payments, refunds, disputes, checkout sessions, payment links, invoices, subscriptions, customers, treasury accounts, account movements and transfers. It can create customers, payment links, checkout sessions and draft invoices, finalize and void invoices, and cancel payment links and subscriptions.

Does the AI see my Fintoc credentials?

No. Your Fintoc 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. Switch on only the tools you want, for example lookups without cancellations. Finalizing an invoice can charge the customer's saved payment method, and voiding an invoice or cancelling a subscription cannot be undone. These actions 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 Fintoc account.

Can I try it in test mode first?

Yes. Use a test secret key (sk_test_) from the Fintoc Dashboard to try the AI without real money. Switch to a live key (sk_live_) when you are ready.
