IDX Integration

Vandulo web developers DX, or Internet Data Exchange, refers to a system that allows real estate brokers to display listings from other brokerages on their own websites. The listings are typically provided by a multiple listing service (MLS) and are made available to brokerages who subscribe to the MLS. By integrating IDX into a website, a brokerage can provide their clients with a wider range of property listings, as well as create a more comprehensive and user-friendly website for home buyers and sellers.



Vandulo Web Development”RETS” stands for Real Estate Transaction Standard, which is a protocol for exchanging data between real estate database systems. “Raw Data integration” refers to the integration of raw data, which means that the data is not processed, transformed, or manipulated in any way, but is instead transferred in its original format. In the context of real estate, raw data integration using the RETS protocol would involve transferring data such as property listings, images, descriptions, and pricing information between different real estate database systems. Vandulo integrating RETS for real estate professionals.

RETS provides a common language so that computers can more easily transfer real estate information, such as MLS data, to other computer programs or websites.  After its creation twenty years ago, RETS is being replaced by RESO Web API, a new standard built on current technology. RESO Web API uses open standards that are well supported in many fields.

Standards such as RETS and RESO Web API allow different systems to communicate easily. Adherence to these standards results in greater efficiency, cost savings, and enhanced user experience. They also encourage greater competition among vendors by allowing anyone free access to the specifications.

As technology changes, so do best practices, data standards, and transport protocol. The Real Estate Standards Organization (RESO) creates, certifies, and updates standards as they are needed. Many multiple listing services are converting their systems from RETS to RESO Web API with many more to make the transition in the near future.


VANDULO Rets & Data Steps For Most accurate Data distribution

RETS (Real Estate Transaction Standard) is a technology standard used in the United States and Canada to facilitate the exchange of real estate data between multiple Listing Services (MLS) and real estate professionals.

To connect to a RETS API (Application Programming Interface) for an MLS, a real estate professional or developer typically needs to follow these steps:

  1. Vandulo Web Development Obtain RETS credentials: The first step is to obtain the necessary credentials from the MLS provider. This typically involves registering with the MLS and receiving a username and password or other authentication tokens required to access their RETS server.

  2. Vandulo Choose an API Client Library: Depending on the programming language being used, the developer can choose an appropriate RETS client library. Several programming languages have existing libraries that handle the complexities of making requests and parsing the data from a RETS server.

  3. Connect to the RETS server: Using the provided credentials, the developer can use the chosen RETS client library to establish a connection to the MLS’s RETS server. We usually make this connection over HTTP or HTTPS. This initial connection will propagate the listings that rest on the MLS platform.

  4. Vandulo Authenticate: Once connected, our developers must authenticate using the provided username and password or authentication tokens. The authentication process ensures that only allowed users can access the MLS data. This normally will require your broker credentials.

  5. Vandulo web developers retrieve metadata: After successful authentication, the developer can request metadata from the RETS server. Metadata contains information about the available resources (e.g., properties, agents), data structures, and supported search parameters. This also called the dictionary.

  6. Search for listings: With the metadata in hand, the developer can perform searches for real estate listings based on various criteria (e.g., location, price, number of bedrooms). The search parameters are typically specified as part of the API request.

  7. Vandulo Retrieve and process data: The RETS API will return the search results in response to the query. The data is usually returned in a structured format, such as XML or JSON. The developer’s application then processes this data to display listings or use it for other real estate-related purposes.

  8. Handle updates and synchronization: MLS data is frequently updated. To keep data current, developers may need to implement mechanisms for incremental updates or periodic data synchronization.

It’s important to note that the specifics of connecting to a RETS API may vary depending on the MLS provider and the version of the RETS standard they support. Since technology evolves over time, it’s recommended to refer to the specific documentation provided by the MLS provider for the most up-to-date information on connecting to their RETS API. Additionally, there may be changes or alternative technologies updates that need to be implemented constantly, to meet demands from clients.

Vandulo web development Real Estate Transaction Standard, RETS provides a common language so that computers can more easily transfer real estate information, such as MLS data, to other computer programs or websites.

RESO’s web API (Application Programming Interface) performs the same function as RETS. But what sets it apart from RETS is that it does not run a query to the MLS database through the IDX server to get results. Instead, the IDX server in the RESO Web API directly contacts the MLS database to receive results

A RETS data feed is a unique raw data connection between your website and your MLS based on the Real Estate Transaction Standard that allows you to import property listings, and with the right software, display them on your website. Many agents use a RETS data feed to set up a property search on their website.

For an agent who is committed to creating a great process around their IDX listing feed and search, it can be helpful to include. For example, with most out-of-the-box IDX plugins, agents can see a wealth of data when the user creates an account, like what they’ve searched, when they’ve searched, and what properties they’ve saved.

But few agents even know what to do with that information, or even know how to access it. But if you’re one of the few that have a process in place for what to do with the information, it could give you an edge with your lead follow and engagement up strategy.

The difference between IDX and RETS concerns the way data is transferred from your MLS to your website. RETS transfers are raw, meaning you need additional software to interpret them on your site. But they are also more flexible and provide for greater SEO than IDX

By creating the data connection between your website and the MLS, IDX integration helps you get prospects from all listings on your website. These listings are automatically updated often, so properties appear or disappear from your site as soon as they are listed or are sold.

RETS is a legacy real estate data standard based on XML that allows a developer to retrieve listing and roster data from an MLS system and replicate it to their own local database. Due to a number of technological limitations the industry is shifting away from RETS to a more modern solution; APIs.

The easiest way to do this is by using the IDX widgets. However at VANDULO we also doing hard-core raw data XML API integration. This is best for organic SEO since all the properties are seating on your servers and are not framed on other third-party servers. Vandulo can integrate widgets on your website  This includes IDX listings, IDX area, IDX search, and IDX single listing widgets. You can also add MLS content to your WordPress posts or pages. Remember that there are set monthly costs for the IDX widget and costs that your MLS will charge you for access.
