# Usage

```javascript
var g23 = require('23andme-node');

g23.getProfiles({token: 'fdab6a6892b198e40c2484bf2121f761'}, function (err, data) {

# Documentation

All methods return a callback with the signature `callback(error, data)`.

`data` and `error` are JavaScript objects.

All methods expect a `params` object with at least the user's authentication `token`.

All methods return the same `data` object regardless of HTTP verb.

Possible error messages:

`invalid_request` - The request is missing a required parameter, or includes an unsupported or incorrect parameter.

`invalid_client` - Client authentication failed (e.g. unknown client, no client credentials included, multiple client credentials included, or unsupported credentials type).

`unauthorized_client` - The client is not authorized to request an authorization code using this method.

`access_denied`	- The resource owner or authorization server denied the request.

`invalid_scope` - The requested scope is invalid, unknown, or malformed.

`unsupported_response_type` - The authorization server does not support obtaining an authorization code using this method.
