How to Add RESO Web API to WordPress

A listing site is unquestionably the most important tool Realtors have nowadays. It is a place where they serve buyers and sellers. MLSs are the biggest providers of listings data, and their members can integrate this data into their sites using the latest technologies, such as the RESO Web API. 

Since WordPress is the CMS of choice for a majority of real estate websites, in this review, we are going to walk you through how to integrate this standard feed into your WordPress real estate website.

Let’s start off with some of the basics. All you need to have a website up and running are:

  • A domain name
  • Hosting 
  • A WordPress plugin 
  • Feed from the MLS

Now, let’s talk about what RESO Web API is and why we should consider it over traditional technologies such as RETS.

What Is RESO Web API?

RESO Web API is a standard method to transfer listings data. MLSs collect property information on their servers, so what you need as a Realtor is a way to bring them to your site. Former technologies such as RETS provided the means to do this, but they were slow, complex, and hard to work around. 

RESO Web API is taking advantage of the capabilities of modern application programming interface to bring the data in a single and more flexible format.

Benefits of RESO Web API?

The Web API has the following advantages over its predecessors:

Better Hosting Options

The Web API allows the use of open data technologies. This in turn limits the need for extensive hosting.

Better Security

RESO Web API has been developed with security as one of the main considerations. Afterall, property listings data are valuable business assets for MLSs and Realtors. 

Coding and Development

API stands for Application Programming Interface, and APIs are designed to allow developers from different backgrounds to be able to work together in one place. This means that you won’t have to spend lots of time and money on finding specialists or limited resources.

Third-party Application

Another advantage of RESO Web API is the flexibility to integrate with third-party applications. Using RESO Web API, Realtors can easily connect a site to a mobile application or another platform; another source of saving time and money.


With over 600 MLSs in the US and Canada, data consolidation and consistency is vital for MLSs. Real estate agents and brokers often wish to work across the borders of their states and MLSs and work nation wide. RESO Web API offers the data consistency for a smooth collaboration between MLSs.

Steps to Integrate RESO Web API Into Your WordPress Real Estate Site
