  1. Clone this repo
  2. Install NodeJS
  3. Navigate to the cloned repo
  4. Initialize the NodeJS app with npm install
  5. All of the dependencies listed in package.json should automatically be installed to node_modules/
  6. Install pm2 using npm install pm2@latest -g
  7. Update pm2

Command Line Summary

# make a parent directory for containing the repo, if desired
mkdir my_bots
# navigate to your desired directory
cd my_bots
# either clone via HTTPS
git clone
# ... or clone via SSH
git clone
# navigate to the cloned repo
cd discord-gitlab-webhook
# install the app via NodeJS, using package.json
npm install
# install pm2
npm install pm2@latest -g
# update pm2
pm2 update


The package.json file includes the following dependencies:

  • discordJS for integrating with Discord
    • erlpack for much faster websockets
  • pm2 for monitoring and maintaining uptime


  1. Create your Discord Bot at Keep this tab open so you can easily access Client ID and Client Secret
  2. Make your Discord app a Bot User by clicking the "Create Bot User" button in your app page settings.
  3. Calculated the desired permissions for your bot at (or use the default 536964096)
  4. Authorize your Discord Bot for your server using{YOUR_CLIENT_ID}&scope=bot&permissions={YOUR_CALCULATED_PERMISSIONS} NOTE: if you get "Unexpected Error" then you probably forgot to turn your Discord App into a Bot User in Step 2.
  5. In your local bot repo, copy the dev/require/config-dummy.json to dev/require/config.json and fill in the data according to the instructions
  6. In your local GitLab server, set up a new webhook using your chosen URL (server.address:server.port), and the DGW_WEBHOOK_TOKEN (or webhook.token) specified in your config file.
  7. Run the bot using pm2 start server.js --name dgw-bot or simply node server.js if you don't want to use pm2
  8. Test the webhook by clicking the 'Test' button in GitLab's integrations page

Using Environment Variables for Secret Tokens (optional)

Instead of keeping your secret tokens in a file, you can choose to set up environment variables and export them for use with the bot script

export DGW_BOT_TOKEN=MySecretDiscordBotToken

export DGW_WEBHOOK_TOKEN=MySecretWebhookToken

Sending Test HTTP Requests

Use GitLab's Tests

In your GitLab instance (either on the web or on your own server), go to Settings > Integrations and find (or create) your webhook. Use the drop-down menu next to your webhook's details to test different event types.

Note that some events will require additional setup on your GitLab instance, such as a .gitlab-ci.yml script for your Pipeline and Job events, and an initial wiki page for your wiki events.

Run the client script

To test HTTP Requests, you can modify and use the client script, ex-client.js:

pm2 start server.js
node ex-client.js

Run cURL

If you want to test HTTP Requests without a GitLab setup, you can use cURL to send fake requests with sample data:

cat sample/push.json | curl -i -v -X POST localhost:9000 -H "Content-Type: application/json" -H 'X-Gitlab-Token: TOKEN' -H 'X-Gitlab-Event: Push Hook' --data-binary "@-"
  • sample/push.json refers to the sample data in the local repo
  • localhost:9000 corresponds to the server.address and server.port in your config file
  • TOKEN is your webhook.token or environment variable DGW_WEBHOOK_TOKEN that you get from Discord when you create/edit a webhook
  • Push Hook is the event that corresponds to the type of data you send, in this case, a GitLab Push Hook

Bot Commands

Debug Mode

>debug or >debug false

Tell the bot whether or not to enter Debug mode. When in Debug mode, any incoming GitLab HTTP requests received by the bot's HTTP server will be printed to your #debug-channel in your Discord server. This can be helpful for figuring out why the data might not be properly displayed by the webhook's embed messages, but can also spam your channel if the data is very long. Only a master user is allowed to use this command.

Clear (Bulk Delete) Messages


Deletes the specified number of messages from the mentioned channel. Only messages from the most recent two weeks will be deleted, as specified by the DiscordAPI. Both the bot and the user must have permission to "Manage Messages" for the specified channel. Also replies to the user to acknowledge receiving the command.

  • NUM must be a number greater than or equal to 2 and less than 100
  • #CHANNEL must be a valid text channel in your guild/server

Disconnect Bot

>disconnect TIME

Tell the bot to stay logged out for TIME milliseconds (default is 5 seconds, max is 1 hour). The bot should automatically log itself back in after TIME is up. Only a master user is allowed to use this command. No commands will be processed during the timeout, but the server will still attempt to listen for incoming HTTP requests (which the bot will try to process when it logs back in).

Embed Sample Data

>embed TYPE

Sends an embedded message via webhook, using data read from the specified sample file. Also replies to the user to acknowledge receiving the command.

TYPE must be one of the properties of the SAMPLE object:



Sends "pong" to the same channel in which the command was called.

Test Embed


Sends an embedded message via webhook, using some placeholder RichEmbed data with Markdown formatting. Also replies to the user to acknowledge receiving the command.


A Discord bot for using webhooks with GitLab (and extendable for other custom webhooks not yet built into Discord).
