Questions

What can the AI do in Lemon Squeezy?

The AI can read stores, products, variants, orders, customers, subscriptions, renewal invoices, discounts and license keys. It can create customers, discount codes and checkout links, generate invoice PDFs, change, pause or cancel subscriptions, and update or disable license keys.

Can I try it in test mode first?

Yes. Lemon Squeezy has separate keys for test mode and live mode. Connect a test-mode key first to see how the AI works with your store, then connect a live key when you are ready.

Does the AI see my Lemon Squeezy API key?

No. Your API key is encrypted at rest and never shown to the AI. Once saved, it is not shown again, not even to you. The AI only works through the tools you switch on.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on. Risky actions, such as cancelling a subscription or disabling a license key, can require your approval before they run. Every tool call is logged, so you can see what the AI did.

Does it work with ChatGPT?

Yes. In ChatGPT, go to 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 works in Claude under Settings › Connectors › Add custom connector, and in Cursor.

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, so you pay for work the AI actually finishes.
