How to Fix Dynamic Pricing Errors

Dynamic Pricing allows merchants to pass pricing options to a CCBill payment form without creating fixed price points in the Pricing Admin.

Merchants must ensure that the variables and values passed to the payment form are accurate and in the correct format. In addition, the subaccount and payment form used to facilitate the transaction need to be configured for Dynamic Pricing.

Refer to the Dynamic Pricing User Guide for a complete overview of Dynamic Pricing variables and settings.

CCBill’s system returns error codes if a dynamic pricing option cannot be generated on the payment form. Error codes and messages are designed to help merchants identify and resolve potential issues.

Dynamic Pricing Error Codes (FlexForms)

The 500 error code is a generic FlexForms error that can occur when passing dynamic pricing variables. It indicates that the parameters in the request string are incorrect or incomplete.

FlexForms 500 Error Code Message

To troubleshoot the dynamic pricing 500 error code:

1. Check Dynamic Pricing Variables

A dynamic pricing request includes multiple variables and values. For example, this request string for a recurring price point contains 8 different parameters:

Solution: Use the Dynamic Pricing guide to check if your request contains all the expected parameters and confirm that their values are in the correct format.

2. Check MD5 Hash

The value for the formDigest parameter is created by joining and hashing multiple variables, including your CCBill Encryption Key (Salt).

Solution: Check the parameters used to create the MD5 Hash and, if necessary, create a new formDigest value.

3. Enable Dynamic Pricing on Payment Form

The FlexForms system awards each payment flow a unique ID.

The Flex ID is the first value included in each Dynamic Pricing request.

Solution: Dynamic pricing needs to be enabled on payment forms used for the transaction.

1. Access the Admin Portal.
