Why teams use Tatum Notifications
Push webhook payloads when something meaningful happens on-chain, without operating indexers or polling nodes around the clock.
Real-time delivery
Subscribe to the events that matter, including transfers, contract logs, and NFT activity, and let Tatum call your endpoint when they fire.
Payload templates
Shape webhook JSON the way your app expects by mapping fields to your own keys. Your endpoint gets a consistent payload without routing responses through extra middleware. Templates documentation
