GitHub Actions Webhook CLI

This example target provides a command-line interface for sending a webhook event to a GitHub Actions workflow.

This example should always be executed from inside this directory (since it searches for a configuration file here).

Quick start

At the end of this quick start, you should be able to receive your arbitrary payload in a GitHub Actions workflow in your own repository, like below:

In this directory, copy config.example.yaml to config.yaml
Create a GitHub App in your account (alternatively use an existing app you have already created)
- The only values you need to fill in is the app name and URL (which can be your GitHub profile URL), and you can uncheck Active under Webhook
- Under Repository permissions, then Contents, grant Read and write permissions (this allows invoking an Actions webhook)
After successful creation, copy the App ID value and replace the example value for the key appId in config.yaml
At the bottom of the same page, under Private keys, generate a private key for your app
Open the generated and downloaded .pem file in a text editor, copy the entire contents, and replace the example value for the key privateKey in config.yaml
Create a new example repository at which to receive your webhook (alternatively reuse an existing repo you have already created)
Copy the repository name and replace the example value for the key repository in config.yaml
Install your new app on your example repository
After successful installation, copy the username of the user or organization you installed the app on and replace the example value for the key username in config.yaml
Copy the file print-payload.yaml to your example repository, at the path .github/workflows/print-payload.yaml, then commit and push the changes

Here are some example commands for sending messages or showing help information about the CLI:

swift run GithubActionsWebhookClient < payload.example.json: send the exact example payload shown above
swift run GithubActionsWebhookClient --help: print the CLI's help messages (which show what values can be configured)
swift run GithubActionsWebhookClient < {path/to/payload}.json: send your own payload file
swift run GithubActionsWebhookClient --payload path/to/payload.json: send your own payload file, without using shell redirection
