Updating the module

To update the payment module you have to:

  1. Uninstall the PayZen payment module from the Add-ons > Manage add-ons menu of the CS-Cart Back Office.

    WARNING: Do not forget to save the parameters of your module before you uninstall it and make sure you save the production key that is no longer visible in the PayZen Back Office.

    Moreover, the new version of the module introduces a new setting: Signature algorithm. By default, this field is set to HMAC-SHA-256 and its value must be the same as in the PayZen Back Office (Settings > Shop). If the algorithm is different, the parameter must be changed via the PayZen Back Office.

  2. Go to the Administration > Payment methods menu, select the PayZen payment module and click Delete.
  3. Please refer to the Adding a payment method chapter to install the new version.
