Building a lottie text editor within my web app

I am looking for developer resources so I might be able to build a lottie animation editor within my web app for customers to add their own text or simple sticker images to an existing lottie animation.

Are there developer resources to perhaps connect through an sdk service to the current lottie editor to pass a text string to the engine to update a text layer and then render the new lottie file animation?

Thanks in advance.
