How to call REST api using Javascript in Designer?

[#1]

I want to first check if the Rest api is online or offline before actually submitting the form to the same. How can I do that using javascript in Forms Designer?

You can also use the FormCalc functions to call a web service and I've an example with this sample Adobe LiveCycle Designer Cookbooks by BR001: Calling a RESTful web service from a PDF form.  Which also shows how to call FormCalc functions from JavaScript.

You get some do you trust this... sort of security messages, but you can select remember decision.

This is something you'll need to setup yourself. The NET.HTTP object provides functionality for making raw HTTP Requests.  It's a matter of setting the request parameters to match the Rest API.

Thanks Thom for the inputs. Can you please share a sample code of the same so that I can try?
