How are the input parameter values pushed back to the user after the save is performed?

Input value	Output value	Description
context_info	id	Any secured information about the file can be passed in the 'context_info' parameter; whereas, we will be pushing it back to you inside the 'id' parameter.
save_format	format	Specifies the 'format' in which the document has been exported.
document_name	filename	'filename' contains the name of the document.
document	content	The edited document will be pushed inside the 'content' parameter.

If you wish to customize the above default keys or add some extra data that you need to send back during save call, it is possible in Zoho Writer service. You can make use of the 'save_url_params' key of 'callback_settings' parameter.
