I am able to call the Identify API to create new profiles with custom properties and update the standard properties.
However, when I make a call to the Identify API web service to update any of my custom properties, the call simply returns a 0 and the profile is not updated.
Is it possible to make updates to these properties through the Identify API after initial insert? If so, could you please provide an example?
If updates are not possible, what API can I use to update properties using the email as key.
