Buildxact Webhooks

Buildxact's webhook surface lets partner and customer integrations receive real-time notifications when events occur inside the construction-management platform — including Estimate Accepted, Lead Created, and Lead Updated, plus additional event types reserved for Merchant and Manufacturer plan tiers. Webhooks are registered from the "My Business > API" panel of the Buildxact web app: provide a destination URL, choose events, store the signing secret used to verify payload authenticity, and inspect deliveries via the built-in Event Log. Payloads are JSON over HTTPS.
