Fireblocks Webhooks API

Receive push notifications when workspace events occur — TRANSACTION_CREATED, TRANSACTION_STATUS_UPDATED, VAULT_ACCOUNT_ADDED, EMBEDDED_WALLET_DEVICE_PAIRED, SMART_TRANSFER events, and more. Each event is signed with RSA-SHA512 in the Fireblocks-Signature header so the consumer can verify authenticity before processing. Webhooks V2 surface adds destination management and replay-from-history.

Operations 2

POST /webhooks/resend Resend failed webhooks #
POST /webhooks/resend/{txId} Resend webhooks for a transaction by ID #
