Getting options from API

We have to show a list of health facilities as answer to a question, and the list will increase time to time. In fact, the list will come from another web based system which has API - GetFacilityList() that can be used,

Is there a way to use result of an API to fill in a form options, instead of manually filling in the list in Excel form design?

@mahmudmia, have you tried using the pull data function as outlined in our support article Pull Data Functionality in KoBoToolbox? Maybe this should be helpful for you to solve your issue.
