Updating the module

To update the payment module, you must first delete its previous version.

WARNING: Make sure you save the parameters of your module before you uninstall it and save the production key that is no longer visible in the Lyra Back Office.

This module version offers this configuration: Signature algorithm which was not present on some previous versions of our modules. By default, this field is set to HMAC-SHA-256 and its value must be the same as in the Lyra Collect Back Office (Settings > Shop > Keys tab). If the algorithm is different, the parameter must be changed via the Lyra Back Office.

To update the payment module:

1. Sign into your ZenCart Back Office.
2. Go to Modules > Payment.
3. Select Lyra - Payment by credit card and click on the Remove Module button.
4. If the installment payment module has been previously installed, select Lyra - Payment in installments by credit card, then click the Remove module button.
