This operation allows you to update selection status, proxy value or coverage customizations for a title within a package in a customer EPKB account. A title with inherited set to true inherits its proxy from the root proxy. So, a JSON payload with inherited set to true updates the title proxy with the root proxy if the root proxy is set. The isSelected payload element is mandatory for managed and custom titles. The titleName and pubType payload elements are mandatory for the custom title update payload. For both managed and custom titles, removing a title with isSelected set to false in the payload will result in a loss of customization made previously at the title level. Removing a custom title with isSelected set to false in the payload will result in the deletion (hard delete) of the custom title from the custom package. If the payload contains ONLY isSelected set to true with no other customization fields, the system will remove all previously set customization. If you do not provide a JSON payload, the JSON payload will be set to the default values and customizations made previously will be lost. If you wish to keep your current customizations, please be sure to set the JSON payload accordingly.
