Real estate API development

1. 01

   Opening your platform to partners

   The product is mature but data is locked inside. A public or partner API turns the platform into an ecosystem that channel partners, aggregators, and third-party developers can build against.

2. 02

   Launching an API product

   Building APIs as a revenue line. Usage-based pricing, per-partner authentication, rate limiting, and a developer portal that allows external teams to self-serve without bottlenecking your engineering capacity.

3. 03

   Standardising internal data exchange

   Multiple internal systems passing data through CSV exports, manual syncs, or fragile point-to-point integrations. A well-designed internal API layer replaces that with structured, versioned, documented data exchange.

4. 04

   Scaling distribution channels

   Listing data needs to reach 10, 50, or 100+ distribution endpoints consistently. Feed APIs, syndication endpoints, and webhook infrastructure ensure every channel receives accurate, real-time property data.

5. 05

   Replacing legacy integrations

   Existing API infrastructure is undocumented, fragile, or built on patterns that do not scale. A rebuild brings modern authentication, versioning, rate limiting, and documentation to an API layer that partners already depend on.

6. 06

   Preparing for enterprise clients

   Enterprise buyers expect API access, sandbox environments, SLA guarantees, and self-serve documentation. The API layer is built to meet the technical due diligence standards that large operators and institutional partners require.

• REST and GraphQL API design

  API architecture designed around your domain model with clear resource boundaries, consistent naming conventions, and query patterns optimised for real estate data structures. REST for straightforward CRUD, GraphQL where clients need flexible querying across complex property relationships.

• OpenAPI specification and per-partner authentication

  Machine-readable API specification that drives documentation, client SDK generation, and contract testing. Per-partner API keys, OAuth 2.0 flows, and scoped permissions ensure every integration partner accesses only the data they are authorised to see.

• Rate limiting and per-tenant quotas

  Usage controls that protect your infrastructure from abuse and allow tiered API access across free, partner, and enterprise tiers. Quota dashboards give visibility into consumption patterns across every integration partner.

• Webhook infrastructure

  Event-driven notifications with configurable triggers, retry logic, delivery guarantees, and event logs. Partners receive real-time updates on bookings, leads, payments, and inventory changes without polling your endpoints.

• Developer portal and interactive documentation

  Self-serve portal with endpoint references, authentication guides, code samples in multiple languages, changelog, and a sandbox environment for testing. Built so partner developers can integrate independently.

• Full IP transfer and source code

  API source code, infrastructure-as-code, OpenAPI specifications, and documentation transfer to your team at handover. No licensing fees, no revenue share, no vendor dependency.
