Edit an existing custom license field. Note that if you want to set the license field values for existing product keys, use the limelm.pkey.setDetails function.


api_key (Required)
Your API application key. Your api key is available on your settings page.
feature_id (Required)
The id of the license field you'll be editing. You can get the license field ID by examining the URL in your browser. For instance, from the URL you can see the license field ID is 42. Also, the license field id is returned when you call the limelm.feature.add web API function.
name (Optional)
The new name of the license field. Maximum 255 characters.
required (Optional)
Whether this license field will be required to be filled out when a new product key is created. Possible values are "true" and "false". If this parameter isn't present (or is invalid) it will default to "true".
ta_readable (Optional)
Whether this license field will be readable from your application using the TurboActivate function GetFeatureValue(). Possible values are "true" and "false". If this parameter isn't present (or is invalid) it will default to "true".
description (Optional)
The description of the license field that will appear when you create and edit product keys. Maximum 255 characters.
default_val (Optional)
Set a default value that this custom license field will have if the value is left blank when creating new product keys.
default_dt_relative (Optional)
If this argument is set to "pkey_created" and the "type" is "date_time", then you can use relative times for the "default_val". The relative time must be in the form [+ | -] N [days | months | years | minutes | hours]. Examples of relative times:
  • + 22 days
  • - 1 months
  • + 2 years
If you're missing the leading +/- symbol then the value will be rejected and an error will be returned. If this "default_dt_relative" argument is set to anything other than "pkey_created" then the argument will be ignored.
