The Problem
Hi there! I want to make a system that checks if you subscribed to a youtube channel and then do an action. So for example: If a player has been subscribed to a channel then… [happens something].
I only don’t know how to check if a player has been subscribed and how I should do that.
I hope some of you can help me out and thanks for reading 
You cannot do this. You would essentially be accessing their email, which is a huge security breach.
Plus why do you even want to check if somebody is subscribed to a youtube channel cha
You can’t do this, you may find/create a proxy.
@incapaxx this is incorrect, many websites can see if you are subscribed to an youtube channel even if you don’t give your gmail/email.
Sadly the TOS interferes in this. The closest way to actually doing this is by checking yourself
Do you have a source? This should not be possible. I believe there some subscription redirect link things, but other than that it shouldn’t be possible.
I want to do this so if people are subscribed to it then they get a free trail.
Well don’t. Use a group instead. Or perhaps a game pass, or badge, even
Yeah, but strucid do this, how do they do it?
Most likely through discord or somebody checking instead of a bot
Does strucid actually do this. It can’t. Because a request to HttpService would have to be made on behalf of the Roblox server.
In strucid, you have to subscribe and then give your channel name so they can manually check.
The short answer is yes, it is possible, but through a third-party service. Strucid does do this, but you would need to have a third-party service, like a website, where you make HTTP requests to, and have that website check if the person is subscribed. You can only see it if they have their subscribers visible to everyone, unless you have access to see their subscriptions through your website. Although Strucid does do this, Roblox does not really allow third-party advertising on games. Either way, you would have to check the ToS. Only way to do it is through a third-party service or website.
But thats bout it. And that’s a huuuuuge invasion of privacy. Hurts UX if you ask me. Plus you can make your subscriptions private which is what many people do 
It’s not really an invasion of privacy if the person has their subscriptions set to visible, but I’m pretty sure the ToS does not really encourage this. I’ve seen posts of staff discussing such things and they don’t really like it.
This will get you a strike/ban if you try to do this, asking for stats to players is a breaking of tos in the first place. Why are you doing this?

I am not gonna make this system, because a lot of you said it’s very hard and it will be a security breach.
Thanks for everyone that responded.
To add on, it is also against the rules to offer a prize in exchange for a like/favourite, so the same concept would apply to subscriptions.

Sorry about the necrobump, but there is a google api that allows you to do this. You just need an api key.

Thanks for letting me know! I don’t need this anymore, but still thanks!
