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.
The domain & endpoint for creating, updating and managing webhooks for mainnet & testnet events is https://api.simplehash.com/webhook_api
All webhook API endpoints require use of an API Key. See https://simplehash.readme.io/reference/overview#authentication for details.
By default, up to 10 webhook subscriptions can be active for a given organization. If you require more than this, please reach out to us at [email protected]
