In short
  • Your API key alone starts a 30-day test.
  • All widgets and Global Styles work during the test.
  • Built-in IDX Broker templates take your styling too.
  • Assigning us within 30 days keeps everything running.

What works with just the key

You do not have to decide anything upfront. Create a free IDX Plugin account, paste your IDX Broker API key where Getting Started shows, and a 30-day test starts on your own MLS data. During the test every ready widget runs, the search forms and the listing widgets, and your Global Styles apply to them and to the built-in IDX Broker templates, like Contact, Mortgage Calculator, Home Valuation and My Account. Set your colors and typography and watch those pages change on your own site.

About the widget list
In the widget list the cards show sample listings on purpose, for performance. Open any widget's Public Preview and your real MLS data renders there.

What the assignment adds

Our custom templates for the key pages, search, results and the single listing page, are the part that needs one extra step: assigning IDX Plugin as your developer partner in IDX Broker. It is free, one email, and it also keeps your widgets running after the 30-day test. After the assignment our templates appear in your template list, as covered in How Our IDX Broker Templates Work.

Start the test

  1. 1 Create a free IDX Plugin account

    Create your free account at dashboard.idxplugin.com/register. It costs nothing and there is no extra invoice, ever.

  2. 2 Paste your API key

    Add your IDX Broker API key in the dashboard, exactly as shown in Getting Started. The moment it is in, the 30-day clock starts and your widgets fill with your own listings.

  3. 3 Test on your own MLS

    Open the ready widgets, run a search, set your brand in Global Styles and watch the built-in IDX Broker pages follow. Everything you configure stays if you assign us later, nothing is thrown away.

  4. 4 Decide within 30 days

    If you like what you see, assign us as your developer partner within the 30 days. Free, revocable anytime, and it unlocks the custom templates on top of what already works.
