Vendor app attempting to Form Post to OutSystems page


We have a vendor system that does form post to other systems and take the response for next action. To test out if this will work with OutSystems, we built a simple page with two fields with an action that return the string. In Vendor App, we can enter names of two fields and the data we want to pass. It also has a field for Form Action which we copied from source of OutSystems. It then tries to call the OutSystems URL and posts the data. 

Unfortunately it is not working and we think the issue is OSVSTATE value as we don't know what value it should be.

Has anyone tried posting data from vendor app to OutSystems page?
