Squarespace is a popular e-commerce / site builder solution. It allows for orders to be taken for products or subscriptions (with payment handled by Stripe).
My use case is I want to see new orders that come in and take the order details to pass on to fulfillment. For this I need to now what products are in the order, frequency of recurring subscription etc.
Squarespace has an extensive API. For examples of triggers / actions see Squarespace Integrations | Integromat
No one else using Squarespace / interested in this? 
I am, add me to the list of wanters!
I’m also keen for a squarespace integration. I’m going to have to use Make.com
Hopefully this gets integrated at some point. It would be awesome. Is it possible to connect n8n to squarespace another way? I’m hoping there is, I’d love to try to figure that out but I’m a coding noob.
You can use HTTP Request node to use Squarespace Commerce API, note that the API available on Commerce Advanced plan or new Core plan and above
Feel free to take inspiration from my recent template to Fetch all Squarespace orders to Google sheet with pagination
