What does BitPay need to locate a bitcoin payment or cryptocurrency payment to an invoice?

BitPay can confirm if a BitPay invoice was paid successfully to the merchant’s ledger. When you need to reach out to BitPay, providing a BitPay Invoice URL (https://bitpay.com/invoice?id=...) helps us assist you quickly.

If you do not have the BitPay Invoice URL, you can provide any of the following, and we will attempt to locate the payment in our system:
