Permissions: patch

Updates a permission using patch semantics. Try it now or see an example.

Warning: Concurrent permissions operations on the same file are not supported; only the last update is applied.

Path parameters
fileId string The ID for the file.
permissionId string The ID for the permission.
Optional query parameters
removeExpiration boolean Whether to remove the expiration date. (Default: false)
transferOwnership boolean Whether changing a role to 'owner' downgrades the current owners to writers. Does nothing if the specified role is not 'owner'. (Default: false)
