Action that uses a webhook for sending automatic styled Discord messages on new repository releases.

Create file discord-release-msg.yml under folder .github/workflows in your project's root folder:

.github/workflows/discord-release-msg.yml

name: Release messages to discord announcement channel

on: 
  release:
    types:
      - created

jobs:
  run_main:
    runs-on: ubuntu-18.04
    name: Sends custom message
    steps:
      - name: Sending message
        uses: nhevia/discord-styled-releases@main
        with:
          webhook_id: ${{ secrets.DISCORD_WEBHOOK_ID }}
          webhook_token: ${{ secrets.DISCORD_WEBHOOK_TOKEN }}

To create a new webhook in discord go to Channel > Edit > Integrations > Webhooks > New Webhook

Once you have the webhoook URL, you can get the ID and the TOKEN. They are included in the URL like so:

https://discord.com/api/webhooks/ID/TOKEN

This is needed to not expose your ID/TOKEN (which would mean anybody can use your webhook)

In your github project go to Settings > Secrets > New repository secret

And add these two secrets (New repository secret button):

Name: DISCORD_WEBHOOK_ID Value: ID (from url)

Name: DISCORD_WEBHOOK_TOKEN Value: TOKEN (from url)

Now every new project release will send a POST using the created webhook, posting a new styled message in the channel where the webhook was created.
