Where can I find my API Base URL?

I have no idea about deep linking but I found a tutorial here: [Adalo Tutorial] How to Share App pages & How to use url parameters for deep linking in a Web app - YouTube which is kinda what I wanted to do.

I have already generated my api key here


but I don’t know what to do at this point?

I went to https://m3o.com/ and created a dev account but I don’t know how to use it or what it does. I don’t see the options Adalo used in the tutorial to understand it Adalo Javascript Component

I think I need to use javascript component to create a deep link that goes to my app pages.

Please help on how can I achieve this?

Goal: I want to create a unique link that goes to a specific event or page within my app.
