Hi,

1. Run Designer studio->Integration->Create Rest Integration 

2. It will create a data page. I renamed it as :D_GetAllmakes"

3.Now have a property ".VehicleMake" against which you want to store the selected make from the dropdown.

4. Have a below setting on the dropdown:

5. On running the case, it will be something like this:

Let me know if this is what you wished for.

I will change this data page to node level as this is a huge page and takes some time to load.

I tried what you suggested but whenever I try to assign the location on the cell of the clipboard I get a "choose a rule" pop-up window and wants me to select a rule. The issue is that it will not save the rule I click, so that when I try to save the cell it says the clipboard location is wrong. I attached a picture to show you. Also could you explain to me why with this REST connector why we do not use a activity or a data transform?

Hi Jonathan, 

Please follow all the steps mentioned by Ranjr, You might be missing declaring pages and classes in your sections pages & classes tab, 

And we use REST connector, cause it will easily create your required components, 

For example: It will parse the Response data and create the data type and data page for using very easily, you no need to manually create it. 

Hi Jonathan,

Can you try selecting the list source as Data page.

Can you please verify the source whether is it a list or not.

Let me know, if you wish i can share the RAP. If that helps?
