Discord Booster/Server Events Add gateway event

[LawMixer]

This would be lovely to have instead of us having to watch for a message or a role add.

Guild members have premium_since property,
which on Guild Member Update event you can compare to old member ( whose you need to cache like many libraries do )

[IllagerCaptain]

Sadly it is not really enough we would like to know when they boost, how many times they boosted overall.

You can't see how many times they boosted overall yet, that's part of #3259, but you can look at the timestamp on premium_since to see when they boosted.

there is a way to see how much the user has boosted

[RealAlphabet]

Yes, but not without violating Discord's terms of use. It is possible to do this with a user token, as the Discord client displays the number of times a user has boosted and when boosts expire.

@RealAlphabet There is no need to recommend using a user token, you can simply say that it is not possible (which was mentioned in the reply above them).

[RealAlphabet]

I'm not making any recommendations here, just stating the facts. If you want to point out that it's forbidden to use a user token, feel free to do so.

Listen for GUILD_BOOST message types sent in the system message channel and get the boost count from the message content.

[IllagerCaptain]

How would the bot know if the user cancels some but not all of their boosts though? Before you say total boost count, that doesn't identity the person in particular.

[LawMixer]

This would be unreliable if the user cancel their boost, it expires, or anything in that nature as @IllagerCaptain said. This would be a QOL feature more likely.
