How can I link a native form to my CRM?

Hello world,

I use SharpSpring for one of my ecommerce clients, and want their Shopify newsletter form to create a lead in our CRM, SharpSpring. SharpSpring provided a code with the following message. Where could I find this? Thank you!

From Shopify:

Place the code below on your website before the closing tag - OR - after the closing tag for the form want to track.

Hi there,

Can you be a little more precise as I have the code from SharpSpring but I am unsure as to what section of code I should add it to? For example, is it the theme code of the framework-newsletter code? I am not a developer but with a limited understanding of how Shopify works so any assistance you can give me to connect my Shopify Newsletter signup form to my SharpSpring account would be very much appreciated.

Best wishes,

Lexrb
