Invite Tracker

Initializing Invite Tracker

tracker = PycordUtils.InviteTracker(bot)

Once you have the above code ready,

@bot.event
async def on_member_join(member):
    inviter = await tracker.fetch_inviter(member) # inviter is the member who invited

Example Cog

Invites.py

import PycordUtils
from discord.ext import commands

class Invite(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.tracker = PycordUtils.InviteTracker(bot)

    @commands.Cog.listener()
    async def on_ready(self):
        await self.tracker.cache_invites()

    @commands.Cog.listener()
    async def on_invite_create(self, invite):
        await self.tracker.update_invite_cache(invite)

    @commands.Cog.listener()
    async def on_guild_join(self, guild):
        await self.tracker.add_guild_cache(guild)

    @commands.Cog.listener()
    async def on_invite_delete(self, invite):
        await self.tracker.remove_invite_cache(invite)

    @commands.Cog.listener()
    async def on_guild_remove(self, guild):
        await self.tracker.remove_guild_cache(guild)

    @commands.Cog.listener()
    async def on_member_join(self, member: discord.Member) -> None:
        # inviter is the member who invited
        if member.bot:
            return 

        inviter = await self.tracker.fetch_inviter(member)
