Hello, how can i get a "webhooks" to use this plugin? Thanks.
(I barely use discord, sometime, but i dont know it so much).

Hey !
I'd say, choose  a discord channel - display its settings (with a right click for example) - and you'll see 'webhooks' in there
create a webhook, you can use default values, just copy URL given on webhook creation window
thats it, this URL is a webhook to use for interacting with this discord channel

Ty, it works wery well; and for what is the "SteamID" on the configuration file? Leaved blank, if i try to reply on discord i get the error:

94.(ip.ip.ip):37973/7656(a number)66/TADMEER-xx Rejecting connection - Steam Auth Failed

making me suppose it's possible a 2-way chat (rust<->discord), but if i write my steam id on the config file i dont receive the error message, but neither the chat message back from discord to rust. 

the purpose of this plugin is to notify a player in chat when the keyword is used.
The steamID in config file is for notifying this player on chat when the keyword is used.
You can choose to notify to chat and/or to a discord webhook.
This plugin doesnt include any 2way chat function.
Only notification, 1 way.
Hope it's clear now ?
