**gateway**

The payment failed because the sequence type is not consistent with previous collections. For example, this error occurs when submitting a RCUR (recurring) payment without a previous FRST (first) payment for the customer, or when the payment sequence does not match the established payment history.

## Recommended Customer Message

The payment sequence doesn't match your previous payments. Please confirm that this is the first payment or follow the appropriate sequence for recurring payments.
