Can anyone advise how to link a page to pop up straight after a purchase?

I'm trying to connect a zap for email marketing with a new form and been advised I can do this by creating a "Thank you for your purchase" page.

I've done this but now not sure how to link the page from the purchase when it happens.

Do I need to add code somewhere?

I have the advanced SS subscription.

Many thanks in advance,

Becky

Try inserting this into the Order Status Page, which you can find under SETTINGS - DEVELOPMENT TOOLS - CODE INJECTION.  You'll want to create a page called /thank-you:

<meta http-equiv="refresh" content="0; url='/thank-you'"></meta>
<style>#_confirmationpage {position:fixed; top:0; left:0; width:100%; height:100%; background:#fff; z-index:2147483646;}</style>
<div id="_confirmationpage"></div>
