Buildout API
Buildout is a connected commercial real estate platform combining CRM, marketing, transaction management, and back-office automation so brokerages can prospect, list, market, and close deals from one data layer. An unofficial API lets you programmatically pull properties, listings, deals, contacts, proposals, and commission records—and push updates like new listings, deal stages, and contact activity back into Buildout.
What is Buildout?
Buildout is a connected software platform built for commercial real estate brokerages, combining CRM, marketing, transaction management, and back-office automation in a single data layer. Brokers and marketers use Buildout to surface likely-to-sell owners, structure property and listing data, generate proposals and marketing materials, manage deals through close, and track commissions—so information entered once flows across prospecting, marketing, closing, and back office without re-entry.
Core product areas include:
- Find & Win (prospecting that surfaces likely-to-sell owners and manages outreach)
- Market (listing marketing automation, brochures, and presentation materials)
- Transact (deal/transaction management, proposals, workflows, and closing)
- Buildout CRM (contact and pipeline hub spanning every stage of the deal)
- Manage & Close (back-office automation and commission tracking)
- Prospect by Buildout and Rethink by Buildout (dedicated prospecting and CRM options) plus an email marketing add-on
Common data entities:
- Properties, Buildings, Spaces, Units
- Listings (for sale and for lease), Offerings, Marketing Materials
- Deals, Pipelines, Stages, Tasks, Activities
- Contacts, Companies, Owners, Prospects
- Proposals, Documents, Brochures, Email Campaigns
- Commissions, Splits, Invoices, Payments
The Buildout Integration Challenge
Brokerages run their pipeline, marketing, and commissions on Buildout daily, but turning those portal-driven workflows into API-driven automation is non-trivial:
- No public developer API: Buildout is delivered as a web application, so there is no documented, self-serve API surface for brokerages to build against
- Multi-product spread: Find & Win, Market, Transact, CRM, and Manage & Close each have their own object models, IDs, and lifecycle states
- Unified data layer to mirror: data entered once flows across prospecting, marketing, closing, and commissions, so a faithful integration must track that propagation
- Authentication and SSO: brokerage logins, SSO, and MFA complicate headless automation
- Document- and template-heavy outputs: proposals, brochures, and marketing materials are generated assets that need careful retrieval and template handling
- Tenant-specific configuration: custom fields, pipeline stages, and commission splits differ per brokerage—generic integrations break across accounts
