Transaction error codes - Wpay

A transaction’s error_code value can be null (for successful transactions) or one of the following for failed and declined transactions.

Core failures

Our system can decline or fail a transaction, in contrast to a connector or payment service rejecting the transaction. When this happens, one of the following error codes can be set as the error_code value.

`error_code`	Description
`incomplete_buyer_approval`	Occurs when a buyer approval redirection times out, this normally means the buyer has closed the redirect page/popup without authenticating
`failed_buyer_approval`	Occurs when a buyer fails to authenticate through 3DS.
`missing_redirect_url`	Occurs when a transaction requires a redirect but was created without `payment_method.redirect_url`
`flow_decline`	Occurs when a transaction is declined by a Flow rule.
`all_attempts_skipped`	Occurs when a transaction fails because no outcome in the matched Flow rule could be used to process the transaction reliably. To avoid this, make sure to define at least one outcome for each possible transaction scenario.

Connector declines

When a payment service rejects or fails the transaction the following error_code values can be set based on the response received from the payment service. The original values received from the payment service will be available in the raw_response_* fields of a transaction record.

The amount column in the tables below specifies the amount that can be used to simulate the error_code when using the Card simulator connector.
