It lists payments that are scheduled but not yet processed.

What your AI can do

Search, create and update payers, and read processed and scheduled payments with status and attempts.

Issue and list refunds, and see which payments, refunds and fees are in each transfer to your bank.

“What made up the last transfer to our bank?”
It finds the transfer and lists the payments, refunds and fees included in it.
“Cancel the subscription for [email protected].”
It finds the payer and the subscription and cancels it, so no further payments are taken. This cannot be undone.

Questions

What can the AI do in Pinch Payments?

The AI can search and read payers, payments, payment links, plans, subscriptions, refunds and transfers, including the line items in a transfer. It can create and update payers, create payment links, delete a scheduled payment, cancel a subscription and issue refunds.

Does the AI see my Pinch credentials?

No. Your Application ID and Secret key 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. Refunds, cancelling a subscription and deleting a scheduled payment cannot be undone, and they 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?

Pinch Payments connects with OAuth, and OAuth connections need the HeyMyApps Pro plan or above. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own Pinch account.

Why not use my Pinch Merchant ID?

Pinch has deprecated the Merchant ID for API access. Instead you create an Application under API Keys in the Pinch portal and use its Application ID and Secret key. HeyMyApps uses them to get short-lived access tokens from Pinch when the AI calls a tool.
