Frequently asked questions

Which payment providers does supastarter support?

supastarter supports Stripe, Lemon Squeezy, Creem, Polar, and Dodo Payments. Each provider is integrated through a unified API, so you can switch providers with minimal code changes.

How do I switch between payment providers?

Switching payment providers involves changing the export in /packages/payments/provider/index.ts to point to your chosen provider, updating the environment variables with your provider's API keys, and configuring your product plans with the correct price IDs from your new provider.

Can I use one-time payments instead of subscriptions?

Yes. supastarter's payment system supports both recurring subscriptions and one-time payments. You can configure your plans with a one-time type in addition to monthly and yearly subscription intervals.

How are webhooks handled?

supastarter automatically handles webhooks from your payment provider to keep subscription status synchronized. It verifies webhook signatures for security, processes subscription lifecycle events (created, updated, canceled, expired), and updates your database accordingly.
