In short
  • Your own listings show up in ready widgets in about a minute.
  • Embed one on your site for the whole 30-day IDX Plugin test.
  • Nothing on your live site changes until you turn it on.
  • Assigning us is free and keeps everything running after that.

No IDX Broker account yet? You open your own account through our registration link, we help you pick a plan and set it up with you, with the $100 setup fee waived through us.

What adding the key actually does

You paste your IDX Broker API key in the IDX Plugin dashboard and a 30-day IDX Plugin test starts. It builds a set of ready widgets for you, search forms and listing widgets, already running on the data from your IDX Broker account. The search forms live on our side. The listing widgets are registered on your IDX Broker account, so the cards can pull your listings. The search form comes set to your own locations, so a search lands on your own results.

Each one is a working widget you can put on your site today. Open Show Embed Code, paste it on a page, and it runs for the 30 days, and past that once you assign us. This is the same search form, live:

Styling the built-in IDX Broker pages is optional

Global Styles work during the IDX Plugin test, and they reach the built-in IDX Broker templates too, like Contact, Mortgage Calculator, Home Valuation and My Account. This part stays off until you switch it on, so nothing on a live site moves while you are only looking around. Set your colors and typography, turn it on for the templates you want, and watch those pages take your brand.

With the key, and after the free assignment

What you're testing With just the API key After the free assignment
Ready search and listing widgets Live on your own listings Keep running past day 30
Global Styles on the widgets Included Included
Styling on built-in IDX Broker pages Included, off until you turn it on Included
Our custom search, results and listing templates Not included Added to your template list

The assignment is naming IDX Plugin as your IDX Broker Developer Partner. It is free and revocable anytime, the account owner sends the request, and it is what adds our templates for search, results and the single listing page on top of what already works.

Start the 30-day IDX Plugin test

  1. 1 Create a free IDX Plugin account

    Register at dashboard.idxplugin.com/register. It costs nothing. IDX Broker pays us for the accounts we support, so your bill stays with IDX Broker.

  2. 2 Paste your IDX Broker API key

    Add the key in the dashboard, exactly as What Is an IDX Broker API Key shows. The 30-day IDX Plugin test starts the moment it is in.

  3. 3 Open your widgets and embed one

    Your ready widgets are waiting in the dashboard, running on the data from your IDX Broker account. Take the embed code and paste it on a page to see it working on your own site.

  4. 4 Try the styling on the built-in templates, if you want

    Set your brand in Global Styles, then turn the styling on for the built-in IDX Broker templates you choose. Nothing on your pages changes until you do.

  5. 5 Assign us when you are ready

    Assign us as your IDX Broker Developer Partner to add the custom templates and keep everything running past day 30. Doing it inside the 30 days avoids a pause, and assigning later brings it all back.
