Is there any plugin that allows digital files to be downloaded only when shared?

As the title above, I have created a website to share free ebooks for everyone, but I want everyone to share the product to be able to download (or share to receive a discount code for that product). Thank you for reading my article.

Oh yeah, that’s a niche but smart request. You could use a WordPress plugin that forces social share before download (like “AccessAlly” or “Social Locker”)—basically locks the file until someone shares it. Just double‑check it plays nice with your theme and caching setup!
