In order to optimize API usage, Memberium lets you control which data you synchronize during login based on your needs.
The Synchronize Ecommerce Records option lets you enable or disable looking up and synchronizing the contact’s ECommerce information during login. This includes order and subscription history, credit card data and invoice data.
If you’re using our eCommerce Shortcodes such as [memb_list_invoices], [memb_list_subscriptions], or [memb_show_receipt] then you’ll need this option turned on in order for that data to be synced into Memberium.
