@Adam_Higgins Welcome to the community. There are a couple of ways to go about this where you can go about this, a simple way would be:
Set up your products in Paystack
Use Webflow CMS to create product pages and but include a link field.
Go to Paystack and retrieve a payment link for each product
Return to Webflow and paste the payment link for each product in the link field you created in your collection
Design the product page template and use a button element in the collection item and in the element settings choose to get the link from the link field you created
Please let me know if you need any more information or if you need visuals and I’ll do a demonstration.
