Is it possible to create an option list that uses multiple REST calls to create the options? There’s a scenario that two REST API calls are needed and some JS work to filter using the data from these 2 REST calls. How can this be achieved?
This is currently not possible with a REST option list in the platform but this functionality is technically possible with custom option lists. The following post (Example Morpheus Option Source Plugin) shows an example of such a custom plugin but it would need to be coded with the desired API calls along with a method for passing the appropriate configuration data.
I have also now created an example for showing how one can execute multiple REST calls per option list: How to execute multiple API requests per Option List: Option Source Plugin Example
