Why did PayPal Here display errors related to auto-generating the invoice number?

You got error messages when PayPal Here tried to generate invoice ID numbers.

PayPal Here automatically increments your invoice IDs based on your previously used invoice ID. If the invoice ID becomes too large, PayPal Here presents an error message.

Here's how to resolve this issue:

  1. Log in to your PayPal account.
  2. Select Money > Send or request money.
  3. Create a new invoice and give it a three-digit invoice number that the system can increment.
  4. Save the invoice. You shouldn't need to send or complete this invoice to stop the error messages.
  5. Log back into PayPal Here and reprocess your payment. You should now be able to proceed without getting errors.
