Build on The Business Lab

Overview

The Business Lab Platform is a multi-tenant property management API designed for boutique residential, mixed-use, and HOA properties. The platform powers production deployments at birminghamplace.thebusiness-lab.com and infinitycapital.thebusiness-lab.com, and is available for white-label integration with strategic partners.

Authentication

All API requests use HTTPS. Two authentication models are supported:

Admin API key stable

Server-to-server, full-property scope. Required for partner integrations and admin operations.

X-Admin-Key: bl_[your-admin-key-here]

Supabase JWT (resident scope) stable

End-user authenticated, resident-scope. Used by the resident portal. Verified against the property's Supabase project.

Authorization: Bearer eyJhbGc...

Rate limits

Default: 100 requests/minute per admin key. 30 requests/minute per resident JWT. Partner integrations receive elevated limits on signed agreement.

Properties

A property is the top-level container for tenants, units, work orders, payments, and operational data.

    {
      "id": "prop_1773430645925",
      "name": "Birmingham Place Residential and Commercial",

    }
  ]
}

Tenants & Owners

A tenant record represents either a renter or an owner (with tenantType: "Owner"). Owners use the same record structure but include HOA-specific fields.

{
  "type": "ach" | "card" | "partner",
  "partner_id": "bilt" | "...",
  "partner_method_id": "...",
  "last4": "1234",
  "auto_debit_enabled": true,
  "auto_debit_day": 5
}

Invoices & Payments

HOA invoicing is monthly-cron-driven for active owners with configured fees, with manual generation also supported.

  "tenant_id": "T-1773675414588",
  "line_items": [
    { "description": "HOA Assessment — June 2026", "amount": 400.00 }
  ],

  "send_now": true,
