Following the recent update to introduce, among other things, direct REST invocation and “hit policies”, Decision Composer Experimental has been refreshed to introduce a set of new capabilities that close the loop on key services.

Testing for Business Users

Now you can test decisions through a GUI that automatically reflects your decision model.


First you define the input data, then you run the decision, and then you check the results. Simple! Alternating between design and test mode, you can try different input values and see the results right away. If you want to understand how to invoke a decision, the JSON description is still there — and the views are synchronized: changes made in one are automatically reflected in the other one.

Exposing Decisions to the World with Decision Forms

This update of Decision Composer brings you the ability to invoke decisions through a shareable form that other people — or RPA bots — can access.

Let’s look at how it works with an example. Here is a very simple decision, which determines a discount based on a quantity and a customer status (say bronze, silver, or gold):


Check out the short video Decision Automation Made Simple to see how to set up a decision like this.

Of course, you use the new testing feature to test your decision. And when you’re happy with the results, you can then publish your decision so that others can try it too.


To make your decision available in a decision form:

  1. Navigate to the home screen for your decision.
  2. Select Execute from the menu for the Discount decision, and choose Decision Form.


  3. The preview shows the form for invoking a decision.
    You can try it out here to double-check that it’s working as you expect.

  4. Edit the URL to replace the placeholder text with a personal API key.
    See Automating the execution of decision projects in the documentation, which explains how get a personal API key.
  5. Share the edited URL
    Anyone who goes to the URL can run your decision.


If you decide to change the logic of your decision, Decision Composer reflects your changes in the decision form.

Beyond friendly testing, you can use this feature to combine decisions and robotic automation to create smart RPA bots: bots that can make decisions as they perform repetitive tasks.
