FAQPage Schema
How do I verify Paddle webhooks in FastAPI?▼

To verify Paddle webhooks in FastAPI, you must handle the raw request body, parse the Paddle-Signature header, and validate it using your PADDLE_WEBHOOK_SECRET environment variable.

What is the Paddle-Signature header used for in webhook security?▼

The Paddle-Signature header is used to verify that webhook events are authentic by validating it against the raw request body and your PADDLE_WEBHOOK_SECRET.

Can I use the Paddle SDK for webhook signature verification instead of manual parsing?▼

Yes, you can use the Paddle SDK for automated webhook signature verification as an alternative to manual parsing across Express, Next.js, and FastAPI implementations.

How do I handle Paddle subscription events in an Express application?▼

You handle Paddle subscription events in Express by configuring an endpoint to receive raw request bodies and verify the Paddle-Signature for events like subscription.created and subscription.activated.

Why does Paddle webhook verification fail without the raw request body?▼

Paddle webhook verification fails without the raw request body because signature validation requires the exact byte sequence received to match against your PADDLE_WEBHOOK_SECRET.
