Does anyone know what format the Mautic API is expecting the data to be to set a Select-Multiple custom field?  
  
  
  
I have a custom field called “interests” with a type of Select-Multiple. I am trying to create a new contact via the API and I am trying to set that field to “Airplanes” and “Helicopters”.  
  
  
  
I can’t figure out what format Mautic wants it.  
  
  
  
In PHP I have tried:  
  
  
  
‘interests’ =\> ‘Airplanes|Helicopters’  
  
  
  
and like “tags” field is handled.  
  
  
  
‘interests’ =\> ‘Airplanes,Helicopters’  
  
  
  
Either way I keep getting an Error:  
  
“interests: This value is not valid.”  
  
  
  
Thank You,  
  
Jody
