404 error when connecting Squarespace to Zapier

Hey,

 

I have a stan store account where I sell a masterclass.

I would like to create a zap connecting my Squarespace so that when someone makes a purchase, Squarespace receives that information and then I can send emails to my buyers from stan.

I have tried to do custom API integrations with Zapier, I even created a new API key in Squarespace but I am still getting a 404 error.

Has anyone else tried this successfully?

Hey ​@theroyaltreatmentinc,

Using custom API is more advanced way of using Zapier. Here is a helpful article about using API’s in Zapier- https://help.zapier.com/hc/en-us/articles/8496083355661-How-to-get-started-with-Webhooks-by-Zapier.

If you are using native Squarespace payments then I would recommend using Webhooks or Email parser for the order confirmation. Try using the Webhook event Order.create to catch when an order is created in Squarespace. See more about it here- https://developers.squarespace.com/webhooks/events/order-create.

I also don’t see any Send Email action for Stan. But you can connect your email provider like Gmail/Outlook and use Send Email action to send the email. Hope it helps!
