Delete all messages in a Discord channel

This works best in Firefox, I haven't tested it in Chrome. On the desktop client, it has trouble getting the Auth token from LocalStorage so you need to grab it from a request's headers and replace the parameter "authToken" on the last line with it. There's instructions on how to do that below.

Preqrequisites:

  • computer
  • general knowledge of your browser's inspector/developer tools
  • possibly even a brain

1. Grab guild and author ids

The script uses the internal id values Discord refers to the selected server and user by. The easy way to do this is to enable Developer Mode in your Discord settings, after which you can simply right click the server's icon and your name and click "Copy ID". Otherwise, you can grab the server's id from the URL, and you can get your own id using the network tab of your browser's inspector.

2. Get your authorization token

This is now automated on Firefox, despite Discord "hiding" the localStorage variable from the DOM. On Chrome and the desktop client it seems to not be in localStorage (???) so you need to get it from a network request. Follow these easy steps:

  1. Open the inspector (Ctrl-Shift-I)
  2. Open the Network tab of your inspector
  3. Open any request to Discord's servers
  4. Look for the "Authorization" request header. Copy that into the line var authToken = "____________your_auth_token_here_______________". For example it might look like var authToken = "mfa.a9ushg92ru9gh9ufhsgjuidfhsgiojfhgjishefrgih3er9u3rg_asdfu9ghauisdfhguiahsdguiahsdigua"

3. Get the script

Copy-paste the script into the javascript console, and replace ____________guild_id_here_______________ and ____________author_id_here______________ with the respective ids copied in Step 1. If you're on Chrome or Desktop Client enter your auth token as well (see above).

4. Launch

Strike the Return key on your keyboard...come on, this is not rocket science man.

FAQ

  • How do I use this to delete DMs? Replace searchURL with https://discordapp.com/api/v6/channels/${guild_id}/messages/search?author_id=${author_id}&include_nsfw=true. For example, replace this line:
const searchURL = `https://discordapp.com/api/v6/guilds/${guild_id}/messages/search?author_id=${author_id}&include_nsfw=true`

with

const searchURL = `https://discordapp.com/api/v6/channels/${guild_id}/messages/search?author_id=${author_id}&include_nsfw=true`
  • How to only delete messages containing some text "abcd"?

Add &content=whatever into the searchURL. For example, https://discordapp.com/api/v6/channels/${guild_id}/messages/search?author_id=${author_id}&include_nsfw=true&content=badword to delete only messages containing "badword".

  • (By @ivmirx) If you want to delete messages before a specific date, do the following:
  1. Open any server to make the search field visible.
  2. Open the "Network" tab in the inspector and clean it from old requests with the trash can icon.
  3. Click in Discord's search field to show the dropdown, then click the "before" option.
  4. Select the date in the calendar.
  5. In the "Network" tab look for the request that contains ?max_id=....
  6. Click on it and copy the max_id=... part from the URL on the right.
  7. Append it to the script's request in the Line 6 by using &.

So now you should have something like: https://discordapp.com/api/v6/guilds/${guild_id}/messages/search?author_id=${author_id}&include_nsfw=true&max_id=540727993958400000 (this example is for 2019-02-01).
