Ecommerce Tracking Code Confusion

I’ve turned on the ecommerce tracking for my website and no ecommerce data is appearing. I’ve seen this page Ecommerce Analytics - Analytics Platform - Matomo and don’t understand what else I’m supposed to be doing. Am I supposed to add extra code to my shopping cart pages. And if so what are the exact steps to doing so?

Check out the existing plugins: Integrations - Analytics Platform - Matomo

Thanks for the link. But I’d like help on implementing this without a plugin.

Then see the doc: Ecommerce Analytics - Analytics Platform - Matomo
