Root Cause

• Bank declined authorization: The issuing bank did not authorize the transaction, possibly due to insufficient funds, account restrictions, or suspected fraudulent activity.

• Incorrect card details entered: The customer may have provided incorrect card information, leading to authorization failure.

• Exceeded transaction limits: The debit card's daily or per-transaction spending limit was exceeded.

• Card issuer security measures: The bank blocked the transaction as part of its fraud prevention protocols.

Troubleshooting and Solutions

• Ask the customer to verify their debit card details and ensure they are entered correctly.

• We recommend that the customer contact their bank to understand why the transaction was declined and resolve any issues.

• We suggest trying a different payment method if the issue cannot be resolved immediately.

• Retry the transaction after the customer confirms that the authorization issue has been addressed.

• Ensure clear error messages are displayed to guide the customer on possible next steps.
