Account Kit Graph API Bad Request
<p>I am using the following graph api endpoint to seek the access token at the server side of my app for the given authorization code.</p>

<p><a href="https://graph.accountkit.com/v1.1/access_token?grant_type=authorization_code&amp;code=authorization_code&amp;access_token=AA|facebook_app_id|app_secret" rel="nofollow noreferrer">https://graph.accountkit.com/v1.1/access_token?grant_type=authorization_code&amp;code=authorization_code&amp;access_token=AA|facebook_app_id|app_secret</a></p>

<p>As mentioned in the Account kit docs for the access_token parameter I have concatenated the following:</p>

<p>"AA" + app id + app secret</p>

<p>Still I am getting Bad Request as response and following error is received:</p>

<p>"message": "Invalid OAuth access token.",
    "type": "OAuthException",
    "code": 190,</p>
