How to manage optional fields in API call

I try to connect the Gravity Form from my wordpress website to one API of the government.

I don’t know how to manage the fields that are optional in the API.


"NomUsage" for example. It is a name. If user write in this field on my Gravity Form, no problem, this is written in the API call : "NomUsage" : "Nameofuser"


But if the user writes nothing in Gravity Form, this is written in the API call : "NomUsage" : "" and the API return an error because it expects the line to be removed.


Could you please help me ?


Thanks a lot !

Hi @Glomaro 

You may need to add custom Code logic to configure the API data JSON structure so it is dynamic.


Hi Troy,


Thanks a lot for your answer, I’ll try that.
