Github Repository Dispatch Notification to Slack & Email

Use the Github integration by MagicBell to setup a workflow when repository_dispatch triggers in Github.

Connect Github to MagicBell to receive events and trigger workflows. This guide uses the MagicBell CLI.

Add the Github integration

Save your Github webhook signing secret in MagicBell. See GitHub webhooks.

magicbell integration save_github \
  --data '{"webhook_signing_secret":"your_secret_here"}'

Copy the ID from the response and use it to build your webhook URL:

https://api.magicbell.com/v2/integrations/github/webhooks/incoming/{id}

Setup the webhook

Setup a webhook in Github with the URL from the last step.
Select the repository_dispatch event.
If you already have a webhook configured, make sure it includes this event.

Add a workflow

Create a workflow that triggers automatically when Github sends this event.

Workflow key

Use this key to trigger the workflow when Github sends a repository_dispatch:

integration.github.repository_dispatch

Example workflow

Track custom webhook events triggered via repository dispatch.

{
  "key": "integration.github.repository_dispatch",
  "steps": [
    {
      "command": "broadcast",
      "input": {
        "action_url": "{{payload.repository.html_url}}/actions",
        "content": "Custom event '{{payload.action}}' triggered on {{payload.repository.full_name}}.",
        "overrides": {
          "providers": {
            "slack": {}
          }
        },
        "recipients": [
          {
            "external_id": "devops-team"
          }
        ],
        "title": "Repository dispatch: {{payload.action}}"
      }
    }
  ]
}

Save with the CLI

Use the MagicBell CLI to save this workflow to your project. You can also use the Workflows API endpoint instead.

magicbell workflow save \
  --data '{"key":"integration.github.repository_dispatch","steps":[{"command":"broadcast","input":{"action_url":"{{payload.repository.html_url}}/actions","content":"Custom event '{{payload.action}}' triggered on {{payload.repository.full_name}}.","overrides":{"providers":{"slack":{}}},"recipients":[{"external_id":"devops-team"}],"title":"Repository dispatch: {{payload.action}}"}}]}'
