LoyaltyLions integration (Server side generated Auth Token)

Hey everyone, I’m migrating from Shopify to Webflow.
I used Loyalty Lions as a loyalty program platform.
I’m trying to follow the instructions and I managed to install the SDK, make it communicate the creation of new members through a zapier zap from MemberStack. Communicate the actions from Webflow.

I only have no idea how to create the auth-token needed for loyalty lions to recognize whether a customer is logged in or not.

The guide is here:

https://developers.loyaltylion.com/sdk/javascript-api/customer-authentication/#creating-the-auth-token

I basically need to use PHP. Is there a way to do what’s in the guide link? A workaround of some sort? Anything?

Please help :frowning: I’m lost
