List of ErrorsThe payment failed because the Level III data required for the transaction is missing, incomplete, or incorrectly formatted. Level III data includes detailed line-item information required by certain payment processors for B2B or government card transactions.

Root Cause

• Missing Level III data: Required fields such as item descriptions, quantities, or tax amounts were not submitted.
• Incorrect or invalid data: Incorrect formatting or values in the Level III fields.
• Gateway requirements: Specific payment processors mandate Level III data for certain transaction types (e.g., B2B or government cards).
• Incomplete integrations: The system did not pass all mandatory Level III fields during the transaction request.

Troubleshooting and Solutions

• Review the payment payload and verify that all mandatory Level III data fields are correctly populated.
• Ensure accurate formatting of line-item details like item names, quantities, unit costs, tax rates, and shipping details.
• Consult the gateway's Level III data documentation for the required field formats and completeness.
• Retry the transaction after ensuring that all necessary Level III information is accurately provided.
• Contact Chargebee Support if the problem persists despite correct inputs.
