Try asking

“Create a payment link for Dana Levi for the two-hour workshop.”
It generates a PayPlus payment page link with the amount, item and customer details. No money moves until the customer pays.
“Show last week's transactions on our main terminal.”
It finds the terminal and lists its transaction history between the dates you give.
“Refund the last charge for [email protected] in full.”
It looks up the transaction and refunds it. The money goes back to the card and the refund cannot be undone.

What your AI can do

Payments and refunds

Create payment page links, look up transactions, read a terminal's transaction history and recurring payments, and refund a charge.

Documents and expenses

List and read invoices, receipts and other documents, create new ones with a draft or preview first, and record and read expenses.

Customers and products

Find, create and update customers and products, and list product categories, terminals and cashiers.

“Make a receipt for Dana's payment, but show me a preview first.”
It creates the document as a preview so you can check it before a final document is made.
“Add a new customer, Cafe Noa, with the email [email protected].”
It checks that the customer does not already exist and creates it with name and email.
“Which recurring payments does Cafe Noa have?”
It lists the recurring payments on the terminal for that customer, and can show one with its schedule, items and status.

Questions

What can the AI do in PayPlus?

The AI can read terminals, cashiers, transactions, recurring payments, payment links, customers, products, categories, documents and expenses. It can create payment links, customers, products, expenses and accounting documents, update customers and products, and refund a transaction if you switch that tool on.

Does the AI see my PayPlus API keys?

No. Your PayPlus credentials are encrypted at rest and never shown to the AI. After you save them, they are 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. A refund moves money back to the card and cannot be undone, and a final document may be emailed to the customer. Both 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 connect your own PayPlus account, so anything PayPlus charges is between you and PayPlus.

Why does PayPlus need a terminal UID?

Many PayPlus payment and report tools work per terminal, such as transaction history, payment links and recurring payments. The AI can list your terminals and cashiers first and then use the right terminal UID, so you do not have to look it up yourself.
