Monitor Polar Sponsorships and Orders in Real Time

Someone just sponsored your project on Polar. Or placed an order. Or cancelled their subscription. Wouldn't you like to know right away? HookBell makes it happen with instant push notifications.

Why monitor Polar webhooks?

Polar is the platform of choice for open source developers and creators who want to monetize their work. Whether you're selling digital products, accepting sponsorships, or running subscriptions, knowing about revenue events in real time helps you engage with supporters and spot issues early.

Supported events

• order.created — "New order: $25.00 from john@example.com"
• subscription.created — "New sponsor: Jane Smith — $10/mo"
• subscription.canceled — "Sponsor canceled: John Doe"
• subscription.updated — Track plan changes and upgrades

For open source maintainers
