The webhook API enables clients to subscribe to Webhook Events.
It complements the existing REST API by allowing users to receive notifications when real-time NFT events occur.
Webhooks eliminate the need for clients to continuously poll via the existing REST API to check for event
occurrence, saving significant bandwidth.
