ECI error codes

What are ECI error codes, and what are they used for?

The ECI error codes are codes that the Tyl By Natwest returns when something goes wrong with your transaction.
These error codes are helpful to you as the business owner and us the support team when we are debugging a problem. Usually, if we know what the error code means, we’ll know how to fix it.

Where can I find these error codes?

A) Tyl By Natwest Backoffice
You can see the error codes if you check your transaction reports.
Navigate from your Tyl By Natwest BackOffice account > Reports > Transactions > then you’ll have to filter the transactions that you’d want to see.

B) WooCommerce Order notes
The error codes can also be seen from your WooCommerce > Orders > view order screen >order notes.
