The webhook API enables clients to subscribe to Webhook Events. It complements the existing REST API https://simplehash.readme.io/reference/overview 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.
