Hi, I know I can use something like:

$params = array(
  'version' => 3,
  'sequential' => 1,
  'contact_id' => 1,
  'group_id' => 2,
);
$result = civicrm_api('GroupContact', 'create', $params);

to add a single contact to a single group (group_id=2).

Is there a method to assign this single contact to multiple groups without having to loop through the previous example.
I tried to put an array but I am getting an error message:

A fatal error was triggered: One of parameters (value: ) is not of the type Integer

Yes, you would have to loop through your contacts, you can not pass an array with multiple groups. So you'd create a loop getting all groups with the API Group Get, and then adding the contact as you are.
