I must be missing something here.
I am using the official PHP SDK and all has been going well BUT now I need to update a custom field (value) associated with a Person.
For example for each Person I have a custom filed, ‘hair colour’ for existing Persons this is null but in some instances I want to update this value from null to blond!
I can add this no problem within the body payload when I create a new Person but I am struggling to update an existing Person when using the UpdateAPerson method.
What am I missing?
Please note I am not trying to update the configuration of the custom field, simply update the value associated with one Person.
