Deprecation noticeWebhooks v1 was deprecated on June 15, 2026. If your integration still relies on v1, it is at risk: v1 no longer receives fixes or enhancements, issue resolution is not guaranteed, and the service may be fully retired at any time without prior notice. Fireblocks is not responsible for missed or delayed notifications or any disruption resulting from continued use of Webhooks v1. Upgrade to Webhooks v2 now via the Developer Center in the Fireblocks Console. For upgrade steps and event mapping, see the Webhooks v2 Migration Guide.
