Receive Wix merchant event

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

<Note>Base44 registers this endpoint with the payment provider for you, and the provider is its only caller. You can't invoke it for your own app or repoint it. It's documented so you can recognize the traffic and read the acknowledgements it returns.</Note>

Receives order and subscription events for a partner merchant selling through Wix Payments.

Base44 registers one of these endpoints per merchant at provisioning time, so the merchant_id in the path identifies which merchant the event belongs to. Base44 verifies the body as an RS256-signed JWT against the public key stored for that merchant when the companion webhook registered, and rejects anything that doesn't verify.

Verified events confirm an order's checkout and update subscription status; revenue and refunds for partner merchants are reported separately through Receive Wix Payments event. A subscription-ending event that arrives before its order still records the ending, so a later order event can't revive it. An event type Base44 doesn't handle comes back as ignored.

<Warning>The response includes fields beyond the ones documented here. Don't rely on undocumented response fields, as they can change at any time.</Warning>
