How to get permissionId in Drive API v3?

Question

I want to delete permission from the file.

In Drive API v2,

PermissionId permissionId = service.permissions().getIdForEmail(account).execute();
service.permissions().delete(fileId, permissionId.getId()).execute();

But According to document, permissions().getIdForEmail(String email) is removed and alternate is nothing.

I can't find how to get permissionId from specific Email address in drive API v3.

Do you have any idea?

Answer 1

I found a simple solution:

        PermissionList permissions = service.permissions().list(sharedFolderId).setFields("nextPageToken, permissions(id,emailAddress)").execute();
        for (Permission p : permissions.getPermissions()) {
            if (p.getEmailAddress().equals(adresseEmail)) {
                service.permissions().delete(sharedFolderId, p.getId()).execute();
            }
        }

Two years later, but your question was the first result I found when searching for a solution. I found a workaround and I hope this will help others with the same issue. This is what I did to get the permission id:

this.getPermissionId = function(emailAddress) {
    return new Promise((resolve, reject) => {

      const input = {
        q:  '"' + emailAddress + '" in writers or "' + emailAddress + '" in readers',
        fields: 'files(permissions)',
        pageSize: 1
      };

      const request = gapi.client.drive.files.list(input);

      request.execute(result => {
        if(result.error) {
          reject(result.error);
        } else if(result.files && result.files[0] && result.files[0].permissions && result.files[0].permissions[0]) {
          const permissions = result.files[0].permissions;
          let permissionId;
          permissions.forEach(permission => {
            if(permission.emailAddress == emailAddress) {
              permissionId = permission.id;
            }
          });

          if(permissionId) {
            resolve(permissionId);
          }

          else {
            reject('permissionIdUndefined');
          }
        }
      });


    })
  };
