Each resource identifies the permission for a specific type (user, group, domain, anyone) and role, such as "commenter" or "reader." For example, a file might have a permission granting a specific user (type=user) read-only access (role=reader) while another permission grants members of a specific group (type=group) the ability to add comments to a file (

For a complete list of roles and the operations permitted by each, refer to Roles.

Note: The list of all permission resources associated with a file, folder, or shared drive, is known as an Access Control List (ACL).

Scenarios for sharing Drive resources

There are 5 different types of sharing scenarios:

  1. To share a file in My Drive, the user must have the role of "writer" or higher.

    • Temporary access (governed by an expiration date and time) isn't allowed in shared drives.

  4. To share a folder in a shared drive, the user must have the role of "organizer."

  5. To manage shared drive membership, the user must have the role of "organizer." Only users and groups can be members of shared drives.

Permission propagation

Permission lists for a folder propagate downward, and all child files and folders inherit permissions from the parent. Whenever permissions or the hierarchy is changed, the propagation occurs recursively through all nested folders. For example, if a file exists in a folder and that folder is then moved within another folder, the permissions on the new folder propagates to the file. If the new folder grants the user of the file a new role, such as "writer," it overrides their old role.

Conversely, if a file inherits the "writer" role from a folder, and is moved to another folder that provides a "reader" role, the file now inherits the "reader" role.

Inherited permissions can't be removed from a file or folder in a shared drive. Instead these permissions must be adjusted on the direct or indirect parent from which they were inherited. Inherited permissions can be removed from items under "My Drive" or "Shared with me."

Conversely, inherited permissions can be overridden on a file or folder in My Drive. So, if a file inherits the role of "writer" from a My Drive folder, you can set the role of "reader" on the file to lower its permission level.

Warning: In "My Drive" and "Shared with me," propagation might stop if a different user owns the child file or folder and the file or folder has more restrictive permissions that override the propagation. For example, a parent folder might have type=group and

Retrieve all permissions for a file, folder, or shared drive

Use the type8 method to retrieve all permissions for a file, folder, or shared drive.

Verify user permissions

When your app opens a file, it should check the file's capabilities and render the UI to reflect the permissions of the current user. For example, if the user doesn't have a type9 capability on the file, the ability to comment should be disabled in the UI.

To check the capabilities, call role0 with the type0 and the role2 parameter set to the 

/**
 * Batch permission modification
 * @param{string} fileId file ID
 * @param{string} targetUserEmail username
 * @param{string} targetDomainName domain
 * @return{list} permission id
 * */
async function shareFile(fileId, targetUserEmail, targetDomainName) {
  const {GoogleAuth} = require('google-auth-library');
  const {google} = require('googleapis');

  // Get credentials and build service
  // TODO (developer) - Use appropriate auth mechanism for your app
  const auth = new GoogleAuth({
    scopes: 'https://www.googleapis.com/auth/drive',
  });
  const service = google.drive({version: 'v3', auth});
  const permissionIds = [];

  const permissions = [
    {
      type: 'user',
      role: 'writer',
      emailAddress: targetUserEmail, // '[email protected]',
    },
    {
      type: 'domain',
      role: 'writer',
      domain: targetDomainName, // 'example.com',
    },
  ];
  // Note: Client library does not currently support HTTP batch
  // requests. When possible, use batched requests when inserting
  // multiple permissions on the same item. For this sample,
  // permissions are inserted serially.
  for (const permission of permissions) {
    try {
      const result = await service.permissions.create({
        resource: permission,
        fileId: fileId,
        fields: 'id',
      });
      permissionIds.push(result.data.id);
      console.log(`Inserted permission id: ${result.data.id}`);
    } catch (err) {
      // TODO(developer): Handle failed permissions
      console.error(err);
    }
  }
  return permissionIds;
}
3 field.

For further information on returning fields using the role2 parameter, refer to Return specific fields for a file.

Determine the source of the role for shared drive files & folders

To change the role on a file or folder, you must know the source of the role. For shared drives, the source of a role can be based on membership to the shared drive, the role on a folder, or the role on a file.

To determine the source of the role for a shared drive, or items within that drive, call role5 with the type0, the role7, and the role2 parameter set to the role9 field. To find the role7, use type8 with the type0.

This field enumerates all inherited and direct file permissions for the user, group, or domain.

Change permissions

To change permissions on a file or folder, you can change the assigned role:

  1. Call type=user3 with the role7 of the permission to change and the type0 for the associated file, folder, or shared drive. To find the role7, use type8 with the type0.

    Note: The role7 represents the user or group to which the permission is granted, such as role=reader0 or role=reader1. The role7 remains the same for that user or group across all files, folders, and shared drives.

  2. In the request, identify the new role.

You can grant permissions on individual files or folders in a shared drive even if the user or group is already a member. For example, Alex has the role of 

/**
 * Batch permission modification
 * @param{string} fileId file ID
 * @param{string} targetUserEmail username
 * @param{string} targetDomainName domain
 * @return{list} permission id
 * */
async function shareFile(fileId, targetUserEmail, targetDomainName) {
  const {GoogleAuth} = require('google-auth-library');
  const {google} = require('googleapis');

  // Get credentials and build service
  // TODO (developer) - Use appropriate auth mechanism for your app
  const auth = new GoogleAuth({
    scopes: 'https://www.googleapis.com/auth/drive',
  });
  const service = google.drive({version: 'v3', auth});
  const permissionIds = [];

  const permissions = [
    {
      type: 'user',
      role: 'writer',
      emailAddress: targetUserEmail, // '[email protected]',
    },
    {
      type: 'domain',
      role: 'writer',
      domain: targetDomainName, // 'example.com',
    },
  ];
  // Note: Client library does not currently support HTTP batch
  // requests. When possible, use batched requests when inserting
  // multiple permissions on the same item. For this sample,
  // permissions are inserted serially.
  for (const permission of permissions) {
    try {
      const result = await service.permissions.create({
        resource: permission,
        fileId: fileId,
        fields: 'id',
      });
      permissionIds.push(result.data.id);
      console.log(`Inserted permission id: ${result.data.id}`);
    } catch (err) {
      // TODO(developer): Handle failed permissions
      console.error(err);
    }
  }
  return permissionIds;
}
2 as part of their membership to a shared drive. However, your app can grant Alex the role=reader5 role for a file in a shared drive. In this case, because the new role is more permissive than the role granted through their membership, the new permission becomes the effective role for the file or folder.

Revoke access to a file or folder

To revoke access to a file or folder, call role=reader6 with the type0 and the role7 to delete the permission.

For items in "My Drive," it's possible to delete an inherited permission. Deleting an inherited permission revokes access to the item and child items, if any.

For items in a shared drive, inherited permissions cannot be revoked. Update or revoke the permission on the parent file or folder instead.

The role=reader6 operation is also used to delete permissions directly applied to a shared drive file or folder.

Transfer file ownership to another Google Workspace account in the same organization

Ownership of files existing in "My Drive" can be transferred from one Google Workspace account to another account in the same organization. An organization that owns a shared drive owns the files within it. Therefore, ownership transfers are not supported for files and folders in shared drives. Organizers of a shared drive can move items from that shared drive and into their own "My Drive" which transfers the ownership to them.

To transfer ownership of a file in "My Drive", do one of the following:

  • Create a file permission granting a specific user (type=user) owner access (type=group1).

  • Update an existing file's permission with the type=group2 role and transfer ownership to the specified user (type=group3).

Note: When a file is transferred, the previous owner's role is downgraded to role=reader5.

Transfer file ownership from one consumer account to another consumer account

Ownership of files can be transferred between one consumer account to another consumer account. However, Drive doesn't transfer ownership of a file between 2 consumer accounts until the prospective new owner explicitly consents to the transfer. To transfer file ownership from one consumer account to another consumer account:

  1. The current owner initiates an ownership transfer by creating or updating the prospective new owner's file permission. The permission must include these settings: type=group5, type=user, and type=group7. If the new owner is creating a permission for the prospective owner, an email notification is sent to the prospective new owner indicating that they're being asked to assume ownership of the file.

  2. The new owner accepts the ownership transfer request by creating or updating their file permission. The permission must include these settings: type=group1 and type=group3. If the new owner is creating a new permission, an email notification is sent to the previous owner indicating that ownership has been transferred.

When a file is transferred, the previous owner's role is downgraded to role=reader5.

Change multiple permissions with batch requests

We strongly recommend using batch requests to modify multiple permissions.

The following is an example of performing a batch permission modification with a client library.

Note: If you're using the older Drive API v2, you can find code samples in GitHub. Learn how to migrate to Drive API v3.
