Root Cause

• Non-numeric or improperly formatted order ID: The transaction request included an order ID in an invalid format, which the gateway could not process.

• Incorrect data type in API request: The order ID field expected a numeric value but received a string or special characters.

• Integration configuration error: The merchant system did not validate or format the order ID correctly before sending it to the gateway.

• Missing order ID in request: The order ID field was left blank or improperly structured in the API payload.

Troubleshooting and Solutions

• Verify that the order ID being passed in the transaction request is numeric and correctly formatted.

• Update the API integration or application logic to enforce correct data types for all required fields.

• Retry the transaction only after ensuring the order ID meets the gateway's formatting requirements.

• Implement input validation to prevent invalid order IDs from being submitted in future transactions.

• If the issue persists, contact the payment gateway and support@chargebee.com for further clarification on accepted order ID formats.
