Ask your AI whether a customer's payment went through, what was in last month's settlements or which subscriptions are active, and it reads the answer from Mollie. It can create customers, payment links, sales invoices and subscriptions, and refund payments, with your approval if you want it.

Questions

What can the AI do in Mollie?

It can read payments, refunds, chargebacks, customers, mandates, subscriptions, payment links, sales invoices, settlements and your organization details. It can create and update customers and payment links, create sales invoices and subscriptions, cancel subscriptions and refund payments.

Does the AI see my Mollie API key?

No. Your Mollie 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 refunds. Refunds send money back, new subscriptions charge customers automatically, and a cancelled subscription cannot be restarted, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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, and you do not need a credit card to start. Paid plans bill per completed task. You also need your own Mollie account.

What is a mandate, and why does a subscription need one?

A mandate is the customer's permission for you to charge them automatically. Mollie needs a valid mandate before a subscription can start. The AI can list a customer's mandates and check this before it creates the subscription.
