Description

The payment failed because required data is missing from the transaction request. This error occurs when mandatory fields are not included, the integration failed to populate required fields, the request payload contains empty values, or gateway schema updates were not implemented.

Recommended Customer Message

We were unable to process your payment because some required information is missing. Please verify your details and try again.

Root Cause

• Incomplete transaction request: Required fields (such as amount, currency, payment method details, or order ID) were not included in the API or transaction request.
• Incorrect integration or API usage: The merchant's system failed to populate mandatory fields before sending the transaction request.
• Data validation errors: The request payload contained empty or null values for critical fields required by the payment gateway.
• Gateway schema updates not reflected: Recent updates to the gateway's required parameters were not implemented in the merchant's integration.

Troubleshooting and Solutions

• Verify that all mandatory fields are provided and correctly formatted in the transaction request.
• Ensure that your integration is up to date with the latest gateway API specifications and mandatory parameter requirements.
• Implement input validation at the application level to prevent incomplete data from being submitted.
• Retry the transaction only after ensuring that no required fields are missing.
• Contact the payment gateway support team if you need clarification on required fields for specific transaction types.
