TaylorKrusen/hs-webhook-example

Clone this repo to your local environment and run npm install.
Copy your HelloSign API Key into the .env-example file and rename it to .env
From the root folder of this repo, run node server to start the express server.
In a separate shell, ngrok http 8080 (port must match PORT in the server.js file). This creates a public url to your localhost which is used for webhooks.
Copy the forwarded https url from ngrok.
In the HelloSign API Settings page, paste the copied ngrok url into the "Account callback" field and append the /hellosign-events POST route defined in server.js. (My callback url looks like this: https://a0a5-50-47-128-110.ngrok.io/hs-events)
Click the "test" button to verify your webhook handler is working. You should see a success message that your server received the test event.
You're all set. Now you can observe callback events as you're tinkering with the API.
