Example Keygen Webhook Handler

The following web app is written in Node.js and shows how to set up a simple webhook handler for Keygen, allowing you to listen for and act upon particular events on your Keygen account.

This example application is not 100% production-ready, but it should get you 90% of the way there. You may need to add additional logging, error handling, validation, features, etc.

Running the app

First up, configure a few environment variables:

# Your Keygen account's Ed25519 verify key
export KEYGEN_VERIFY_KEY="YOUR_KEYGEN_ED25519_VERIFY_KEY"

# Your Keygen account ID.
export KEYGEN_ACCOUNT_ID="YOUR_KEYGEN_ACCOUNT_ID"

You can either run each line above within your terminal session before starting the app, or you can add the above contents to your ~/.bashrc file and then run source ~/.bashrc after saving the file.

Next, install dependencies with yarn:

yarn

Then start the app:

yarn start

Testing webhooks locally

For local development, create an ngrok tunnel:

ngrok http 8080

Next up, add the secure ngrok URL to your Keygen account to listen for webhook events.

1. Keygen: add https://{YOUR_NGROK_URL}/keygen to https://app.keygen.sh/webhook-endpoints

You can now create events within your Keygen account, e.g. create a new license, and the webhook event will be sent to your local server.
