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.

Buildxact Webhooks is one of 5 APIs that Buildxact publishes on the APIs.io network, described by an AsyncAPI event-driven specification.

Tagged areas include Webhook, Event, Estimates, Leads, and Event-Driven. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

This event API exposes 3 operations across 3 channels, and defines 6 schemas. It is described by AsyncAPI 2.6.0, at version 1.0.

The API connects through a single server, {webhookUrl} (https).

Where this information came from

This is an independent, third-party profile of Buildxact Webhooks, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
