Get contacts AUTH Fail

[biswajitdas]

Hi, These are the sample value I have used

const MESIBO_ACCESS_TOKEN = "USER_AUTH_TOKEN";
const MESIBO_APP_ID = "APP_ID";
const MESIBO_API_URL = "https://app.mesibo.com/api.php";

The logs populated in console :

init_messenger called sessionReadSummary complete fetchContacts called getting contacts Error: fetchContacts: getcontacts request failed MesiboNotify.prototype.Mesibo_OnConnectionStatus: 6 sessionReadSummary complete MesiboNotify.prototype.Mesibo_OnConnectionStatus: 1

I am getting an error

{
    "op": "getcontacts",
    "error": "AUTHFAIL",
    "result": "FAIL"
}

Can you guide me to the relevant documentation?

Thanks.
