At the moment, SimiCart's reward points feature is compatible with Magestore Standard Reward Point extension only. In case you are using other extensions in your website, your online store will have 2 separated point systems.
There are 2 options in this case if you want to combine these 2 systems:
1. Request customization service to integrate the Reward Points system in your website with SimiCart.
2. Transfer to use Magestore Reward points extension in your website.
If you want to know more about these 2 solutions, please contact SimiCart's technical team for futher discussion.
