Our webhook implementation follows the Standard Webhooks specification and our SDKs offer:
  • Built-in webhook signature validation for security
  • Fully typed webhook payloads
In addition, our webhooks offer built-in support for Slack & Discord formatting. Making it a breeze to setup in-chat notifications for your team.

​
Get Started

Use our sandbox environment during developmentSo you can easily test purchases, subscriptions, cancellations and refunds to automatically trigger webhook events without spending a dime.
1

Add new endpoint

Head over to your organization settings and click on the Add Endpoint button to create a new webhook.
2

Specify your endpoint URL

Enter the URL to which the webhook events should be sent.
Developing locally?Use a tool like ngrok to tunnel webhook events to your local development environment. This will allow you to test your webhook handlers without deploying them to a live server.Once you have ngrok you can easily start a tunnel:
Terminal
ngrok http 3000
Just be sure to provide the URL ngrok gives you as the webhook endpoint on Polar.

Choose a delivery format

For standard, custom integrations, leave this parameter on Raw. This will send a payload in JSON format.If you wish to send notifications to a Discord or Slack channel, you can select the corresponding format here. Polar will then adapt the payload so properly formatted messages are sent to your channel.If you paste a Discord or Slack Webhook URL, the format will be automatically selected.

Set a secret

We cryptographically sign the requests using this secret. So you can easily verify them using our SDKs to ensure they are legitimate webhook payloads from Polar.You can set your own or generate a random one.
