Issue
When submitting payment, customers see the error message:
… main.CRITICAL: Exception message: PayPal gateway has rejected request. Payment has already been made for this InvoiceID (#10412: Duplicate invoice).
PayPal cannot process the payment and complete the order.
Cause
The error message is displayed when invoices with the same ID are submitted to PayPal multiple times.
This may happen when using the same credentials across several ÃÛ¶¹ÊÓƵ Commerce sites (even across the Local and the Staging environments). Particular scenarios might be the following:
- Multiple stores submit invoices to PayPal and use the same invoice IDs.
- A new store sends an invoice with an ID that has been previously submitted by an old store.
By default, PayPal does not allow processing for the same invoice twice.
