To add a custom ID to an engaging element - Button, Swipe Up, and Product Tag, go to StorifyMe Editor. Find the Engage tab in the left sidebar and choose an engaging element you want to add to your story.
After you choose the element you want to engage the audience with, assign action and link to the website you want to lead the audience. Also, you can change the design of your button and add custom colors, borders, etc.
The final step for button editing is setting a custom analytic ID, that will help you track the performance of your engaging elements better. From now on, you can track the performance of button groups by assigning the same ID for multiplied buttons (CTA button, Product Tags, Swipe Ups) in StorifyMe Analytics.
