Hello guys, I'm sorry that I have to bother you today with such a question but I have now 3 hours, clicked through everything and I can't get RustCord to send the kills to Discord. Please help me.

here is the Code

"Output Type: Deaths (Simple/Embed/DeathNotes)": "DeathNotes",

{
"Discord Channel ID #": "940376462924611595",
"Channel Flags": [
"plugin_deathnotes_pvp",
"plugin_deathnotes_animal",
"plugin_deathnotes_npc",
"plugin_deathnotes_vehicle"
"death_pvp",
"death_npc",
"death_animal",
"death_vehicle",
],
"Custom: Words/Phrases to Log": [
"keyword1",
"keyword2"
]
}

I hope you guys can help me

Where'd you find the "plugin_deathnotes_pvp", etc lines?  I didn't see those in the docs.

1st: I believe it's redundant.  Not sure you need both the "plugin" and plain lines.  
Next, after plugin deathnotes vehicle... there must be a comma, if you're going to have all 8 entries.  Each entry needs a comma, except the last one -- "death_vehicle" in your case.

Any errors when reloading?  Or just doesn't log?

Merged post

Try this:

{
"Discord Channel ID #": "<Your ID>",
"Channel Flags": [
"plugin_deathnotes_pvp",
"plugin_deathnotes_animal",
"plugin_deathnotes_npc",
"plugin_deathnotes_vehicle"
],
"Custom: Words/Phrases to Log": [
"keyword1",
"keyword2"
]
},

@TheProfessor i dont know it still dont working :/

Double check your channel ID info: right click the channel, and choose "copy ID", and paste it in there.  Reload and test it - go kill a bear or something.

Do you have any channels working?  Or is it just this one?

The above config section I sent you is working great for me.  I checked the .cs file and I see the plugin_deathnotes commands you used.
When you reload, do you receive any error messages?
