Hey! When you say 'my users the possibility to cancel the operation before their customers present their payment method', you men from the POS you're building or the Terminal device?
Is cancelCollectPaymentMethod only usable after the payment method has actually been collected ?
That shouldn't be the case

Yes from the POS, from what I've seen there's no option to cancel the operation directly from the device

Can be done with allowCustomerCancel yep, but not sure what status of that parameter is: https://stripe.com/docs/terminal/references/api/js-sdk#reader-behaviour-configuration
Can you share your code where you're calling cancelCollectPaymentMethod? I'd expect that to work if there's an a collectPaymentMethod instance active

This is a react app, I'm passing this function as a prop to another component. However, at the time when this function is defined, the collectPaymentMethod hasn't been called yet on my terminal instance.

Hi! I'm taking over this thread.
If I understand correctly you are calling cancelCollectPaymentMethod() but it doesn't work as expected? Do you get an error message?
analog gazelle
I get the following error:
Unhandled Rejection (Error): Invalid state: cancelCollectPaymentMethod() cancels an active attempt to get a payment method from a customer. However, there was no active attempt.
The error's description states "cancelCollectPaymentMethod can only be called when collectPaymentMethod is in progress.", but collectPaymentMethod returns a Promise that resolves when the customer presents his card on the reader. In my use case, I would like to cancel when this Promise is still pending (the card hasn't been collected yet)

Sorry for the delay, asking a colleague about this.

Nevermind, I found the solution to my problem. I was stuck because I was using async / await to define my cancel handler. Switching to .then() promise chaining solved it for me, thx
