I have an idea for a business that makes custom videos for people through a web app. The hope is that people will want to share these videos on social media and my business will go viral. I'm trying to figure out if there is a way to make it easy to share on Instagram and TikTok, something like the share button you'd find in an app, which opens a menu to select which app you'd like to share on.
Is this possible from a webapp? Is there a link I can send the user to that will tell Instagram/TikTok the URL of the video they want to share? Or an API I can use? Thanks
