I had an error code processing payments on Opayo and I want to understand what went wrong
If the payment gateway from Opayo/Sagepay is returned you can go to
https://www.opayo.co.uk/support/error-codes to check what the error code means.
In most cases, it will be an incorrect character submitted that their gateway did not like.
For Opayo, Paytia is configured to pass;
VendorData in the Paytia Account Number field
VendorTxCode in the Paytia Reference number field
| Opayo field | Valid characters | Max characters | Notes |
| VendorData | Letters, digits, and spaces | 200 | This is optionally used to pass any data you want displayed against the transaction in MySagePay. |
| VendorTxCode | Letters, digits, hyphens, periods, underscores, and curly brackets | 40 | Your unique transaction reference. You must use a new and unique VendorTxCode for each transaction. |
