This action allows users to set up a GitHub Action that calls Discord webhooks with content message and, optionally, a custom username and avatar url.
Name | Required | Description |
---|---|---|
webhook-url | true |
Webhook URL from discord. See: the intro to webhook docs for details |
content | true |
Message that is send via the webhook. |
username | false |
The username that should appear to send the message. Note: username will have the "bot" badge next to their name. |
avatar-url | false |
URL for the avatar that should appear with the message. |
raw-data | false |
Filename of raw JSON body to send. If this is provided, all other inputs (except webhook-url ) are ignored. |
filename | false |
Filename of file to upload. This input is overridden by raw-data . If this is provided, all other inputs (except webhook-url ) are ignored. |
PSA: Do not commit your webhook URL to a public repository. Webhooks do not require authentication, so anyone who has the webhook can use it.
GitHub repositories support secrets (under settings->secrets
). Encrypt your webhook URLs.
GitHub Actions allow users to set up various triggers. One of the triggers is schedule
. This allows users to set a POSIX cron timer to run the action.
Below is an example that sends the message "Test"
to the provided webhook.
on:
schedule:
- cron: '0 12 * * *'
jobs:
message:
runs-on: ubuntu-latest
steps:
- name: Discord Webhook Action
uses: tsickert/discord-webhook@v3.0.0
with:
webhook-url: ${{ secrets.WEBHOOK_URL }}
content: "Test"
Disclaimer: GitHub Actions don't seem to always respect the cron job precisely. My experience has been that crons run about 15 minutes after they're scheduled to and crons that should run per minute will likely only run once every 7-10 minutes.
on:
workflow_dispatch:
jobs:
message:
runs-on: ubuntu-latest
steps:
- name: Discord Webhook Action
uses: tsickert/discord-webhook@v3.0.0
with:
webhook-url: ${{ secrets.WEBHOOK_URL }}
content: "Test"
Multiple triggers are allowed for actions, so the action can have a manual trigger and a cron trigger:
on:
workflow_dispatch:
schedule:
- cron: '0 12 * * *'
Do you need to send more than just some basic content? Things like embeds, for example? That's supported in v2.0.0
and above.
Instead of providing content inputs, you can override the
raw-data
input with the path to a JSON file in your repository that contains your webhook message.
(Note that all inputs except for webhook-url
are ignored when raw-data
is provided)
Let's say we want to send a message with an embed.
Add a JSON file to your repository with the content you want (for this example, this file is called hi.json
).
{
"content": "See greeting below",
"embeds": [{"title":"Hello","description":"World"}]
}
IMPORTANT: Then, in the yaml where you define this action, you need to do one very important step, and that's adding a step to pull in the files from your repository.
- uses: actions/checkout@v2
This will allow the action to read the JSON that we added to the repository.
The final action will look something like this:
name: Hi
on:
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Discord Webhook Action
uses: tsickert/discord-webhook@v3.0.0
with:
webhook-url: ${{ secrets.WEBHOOK_URL }}
raw-data: hi.json
Do you need to upload a file? Maybe you have a built artifact that you want to share or a daily update on progress
that's tracked in a file. That's supported in v3.0.0
and above.
Instead of providing content inputs, you can override the filename
input with the path to file in your workspace.
(Note that all inputs except for webhook-url
are ignored when raw-data
is provided)
(Note raw-data
overrides this input if it also provided)
Let's say we want upload a file.
Add file to your repository or workspace via an action (for this example, this file is called test.txt
).
IMPORTANT: If you added the file to your respoitory, don't forget to pull in the files from your repository.
- uses: actions/checkout@v2
This will allow the action see any files from the repository in the workspace.
The final action will look something like this:
name: Hi
on:
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Discord Webhook Action
uses: tsickert/discord-webhook@v3.0.0
with:
webhook-url: ${{ secrets.WEBHOOK_URL }}
filename: test.txt
Q: Can I use @
pings with this? They just show up as plain text.
A: Yes! Plaintext discord messages use the following syntax for @
s: <@{user-id}>
for users (example: <@123456790>
) and <#{channel-id}>
for channels (example: <#123456790>
). The easiest way to find your user ID or channel ID is to enable developer mode and then right click on a user or channel and select Copy ID
. To enable developer mode, go to settings(cog wheel)
-> Advanced (under App Settings header)
-> Developer Mode
.
