Does anyone know what the difference in functionality is between Allow Blank and Optional in the parameter section of the API connector?
If you check Optional next to name, you won’t have to add name as a parameter in the payload of the request at all.
If you don’t check Optional but do check Allow blank, you’ll have to set a value for name, which can be "" or null.
If you don’t check Optional and don’t check Allow blank, you’ll have to set a value for name, which will have to be a truthy value (so "" or null won’t be allowed).
