How can I check/retrieve the Branch Link behind any given banner?

Load your Chrome desktop browser, enable developer tools by pressing ctrl+option+i, ensure the mobile view is selected, and then load the webpage with the banner. In the network tab of the developer tools, filter all requests by “branch” and inspect the “https://api2.branch.io/v1/pageview” request. In the network response, search for “app.link” and you’ll find a reference to the actual link that was embedded behind the button (you can then copy this link and append “?debug=1” to inspect its data)
