Protect the unprotected Document

This REST API adds a protection to a document.

A password is always required. If you want to change the type of protection, then ProtectionType is required. If you want to change the password, then NewPassword is required. If you want to change both of the type of protection and the password, then both ProtectionType and NewPassword are required.

The important properties are described below:

Property Name Type Description
ProtectionType string Document protection type, one from: AllowOnlyComments, AllowOnlyFormFields, AllowOnlyRevisions, ReadOnly, NoProtection.
Password string Current document protection password.
NewPassword string New document protection password.


The OpenAPI Specification defines a publicly accessible programming interface and lets you carry out REST interactions directly from a web browser.
