Hi FLucas and welcome to [meta.discourse.org](http://meta.discourse.org/) :blob_wave:

By reverse-engineering the API, I understood that the usernames must be separated with a comma without space. If you’re trying to add multiple users at once, it may be your issue.

I tested with the following payload:

```json
{
    "group": {
        "name": "test",
        "bio_raw": "test",
        "full_name": "test",
        "usernames": "Canapin,adan",
        "owner_usernames": "cristopher_klocko,Canapin"
    }
}

```

As a POST request to `admin/groups.json`, and it worked.
