Connect an existing business system to MLS RealtyHub without creating another isolated data process. The MLS RealtyHub API gives technical teams a programmatic way to send and receive supported real estate data, while the business keeps its CRM, website, portal or wider data stack at the centre of its own workflow.
Keep the systems your business already uses
An agency may already have a CRM for its commercial process, a website for public presentation and internal tools built around its own operating model. The problem begins when property information has to be copied between them. Manual exports create extra hand-offs, incompatible formats require repeated adjustment, and the same record may need to be entered more than once.
The MLS RealtyHub API creates a connection point between MLS RealtyHub and that existing technical environment. It is designed for business buyers who need to define the operating requirement, and for technical teams or integration partners who will assess and implement the data exchange.
What can move through the MLS RealtyHub API
The API covers three resource groups:
- Listings
- Projects
- Data Products
For supported data within that scope, the API can send information from MLS RealtyHub to another system and receive information into MLS RealtyHub. This makes the full API different from an outbound-only feed. The exact fields, routes and rules are defined for each implementation.
What stays outside the confirmed scope
User resources are outside this scope. Lead and Inquiry data are not currently available for transfer to third-party sources through this API. A property-data connection does not provide access to personal, lead or enquiry records through the same route.
Start with the exchange, not the endpoint
A useful API project begins with a business sentence: “When this information changes here, this other system needs the agreed version.” That sentence identifies the source, destination and purpose before the technical team chooses an implementation approach.
Define the workflow before development
Before development starts, the business and technical participants need to agree:
- which resource group is involved;
- whether MLS RealtyHub sends the data, receives it or does both;
- which system owns each step of the wider workflow;
- what event or business process should initiate the exchange;
- what access and configuration are required;
- how the result will be checked and used in the next step.
This definition matters because the presence of an API does not make every external application a ready-made integration. It provides a programmatic route that a technical team can use within an agreed scope.
A practical agency scenario
Consider an agency that already manages internal commercial activity in its own system but wants supported property information to move between that environment and MLS RealtyHub. The agency head defines the business outcome, while the technical team or integration partner translates it into a controlled exchange.
- The team identifies whether the workflow concerns Listings, Projects or a supported Data Product.
- It defines which system provides the information and which system needs to receive it.
- The technical participants confirm access, available fields, the delivery logic and any implementation dependencies.
- They configure and test the connection against the agreed workflow.
- Once the exchange is working, the receiving system uses the data in its next business step instead of relying on a separate manual transfer.
The result is a defined route between systems. MLS RealtyHub remains one participant in the data flow, while the agency keeps responsibility for deciding how the connected system uses the information it receives.
Where the routine work can be reduced
When the connection is configured for an agreed flow, systems can exchange the supported data programmatically. This can remove the need to prepare the same manual export each time that flow runs and reduce repeated entry between the connected environments.
The API does not remove the need for ownership and review. The client and technical team still need to define the data scope, validate the mapping, decide what triggers the exchange and check that the receiving system handles the result correctly. A successful result still depends on the agreed scope and the connected system’s handling.
Choose the right route for the job
The full API sits inside the API, Feeds and Integrations module, but it should not be confused with every other capability in that module.
- The MLS RealtyHub API supports programmatic sending and receiving of Listings, Projects and Data Products within an agreed scope.
- MLS RealtyHub API-Lite is the lighter, Listings-only option.
- Property JSON and XML Feeds provide organised outbound property-data delivery in defined formats.
- A CRM Integration is a specific connection with an external CRM. It is available on request and requires its own scope.
- Data Migration is a one-time transfer service when substantial work is performed by the MLS RealtyHub team; it is not the same as recurring exchange through an API.
The choice follows the workflow. Use the full API when the requirement involves Listings, Projects or Data Products and needs a programmatic send or receive mechanism. Choose API-Lite for a narrower Listings-only use case, a feed for organised outbound delivery, or an individually scoped integration when the requirement centres on a particular external system.
Confirm the technical boundary before you build
The MLS RealtyHub API is Live. Endpoint details, payload structure, authentication, rate limits, development environments and delivery behaviour are established as part of the technical scope for the proposed connection. Your team should use those implementation details when designing the workflow.
The same rule applies to compatibility. Access to the API does not guarantee that any CRM, portal or website can connect without assessment or configuration. Resources, direction, fields, access conditions and delivery behaviour need to be agreed for the use case.
Define the connection before development starts
Bring the systems, resource scope and required direction to the MLS RealtyHub integration team. They can confirm the technical scope, access conditions and the appropriate route for the workflow.
