Hi,
1 - In the following endpoint I known that the profile parameter is the name of the form but what is the key parameter and where I can look for it?
    
        
             
    
2 - Is there how to known the total entries of a lookup table? 
3 - How can I use the filter query parameter to seach for more than one field with an or clause? For example I want to be able to search for all the fields below.
    
        
             
    
    
        
             
    
Thanks
