Zeno works well with many other apps on the market.
Some Shopify apps, and standalone apps (e.g. Klaviyo) require inserting a snippet of code into the theme. With Zeno, things get much easier.
First, you need to get the code snippet of the other app. You should find them in the app dashboard, or the app documentation.
Using Custom code element, you can insert the code into the page anywhere you want.
