Creating a Telegram profile link from user messages in a bot

I’m developing a Telegram bot and I’m stuck on a problem. How can I generate a link to a user’s profile when they send a message to my bot?

Here’s what I’ve got so far:

@Override
public void onUpdateReceived(Update updateInfo) {
    User sender = updateInfo.getMessage().getSender();
    
    // I can get these, but they're not what I need
    String firstName = sender.getFirstName();
    String lastName = sender.getLastName();
    
    // This gives me a number, but how do I turn it into a profile link?
    long userId = sender.getId();
}

I can get the user’s name and ID, but I’m not sure how to create a clickable link to their Telegram profile. Is there a way to do this using the Telegram Bot API? Any help would be great!

I encountered a similar issue when developing my Telegram bot. The solution is actually quite straightforward once you know the trick. You can create a profile link using the user’s ID in this format:

https://t.me/user?id=USERID

So in your case, you’d do something like this:

String profileLink = "https://t.me/user?id=" + userId;

This will generate a clickable link to the user’s profile. You can then use this link in your bot’s responses or store it for later use.

Keep in mind that this method works for most users, but there are some exceptions. For instance, users with usernames will have a different link format (Telegram: View @username). Also, some users might have their privacy settings configured to prevent linking to their profiles.

Hope this helps solve your problem!

hey alexlee, i’ve dealt with this before. you can make a profile link like this:

String profLink = “https://t.me/” + userId;

it’s simple but works for most users. just remember some folks might have privacy settings that block it. good luck with ur bot!

The solution to your problem lies in utilizing the Telegram API’s tg://user?id= format. This creates a universal link that works across all Telegram clients. Here’s how you can implement it:

String telegramLink = “tg://user?id=” + userId;

This generates a link that, when clicked, opens the user’s profile in the Telegram app. It’s more reliable than web links as it works regardless of the user’s privacy settings.

For web-based applications, you can use the https://t.me/ format:

String webLink = “https://t.me/” + userId;

Remember, these links won’t work for users who haven’t set a username. In such cases, you might want to handle the exception or provide an alternative way to reference the user.
