So not the current invoice?

[vale pagoda]

is there any field I can use from the invoice

so, after my customer pays the first invoice for the subscription I want to make that payment method the default payment method

and after receiving the webhook for invoice paid I want to get the payment method he used during the payment

[frigid ridge]

Okay that is pretty straightforward

[vale pagoda]

what field can I use?

[frigid ridge]

You would have to retrieve the related Payment Intent (invoice.payment_intent) and then get the Payment Method ID from the Payment Intent object returned.
