result=error;message=Authentication Failed

[KGV Consulting]

Hey, I'm trying to test WHMCS API Authentication using "Postman" and continue to get Authentication error - 403 Forbiden

the WHMCS activity log does not record anything, Im using json, all setting described in the development documentation are executed,  here is sample of the code:

POST /whmcs/includes/api.php? HTTP/1.1

Host: mydomain.com

Content-Type: application/json

cache-control: no-cache

Postman-Token: ############################

{

    "action": "DomainWhois",

    "username": "Identifier",

    "password": "Secret",

    "accesskey": "accesskey",

    "domain": “testdoamin.com",

    "responsetype": "json"

}------WebKitFormBoundary7MA4YWxkTrZu0gW--

Im continuing to get that error. Any advice how that can be corrected or fixed?

I don't use PHP, prefer JavaScript, Python instead

Thanks

Under WHMCS admin -> Setup menu -> General Settings -> Security tab, do you have the IPs you're connecting from listed in "API IP Access Restriction" ?   If not, add them and see if that helps.

Hi steven99, I did that, the IP is listed, also I set up access key as described in the documentation: https://developers.whmcs.com/api/access-control/ by doing that I could avoid whitelisting of every IP that would access the server, regardless of those steps Im continuing to get this error. Also I'm using WHMCS v7.7 and PHP 7.2.14

I have the same Issue. From Potsman and from Micorosft Flow: 

"Authentication Failed"

I have a similar issue.
I am trying to call an API endpoint in WHMCS from a laravel app.

 

public function exec(String $action = null, Array $data = [], String $responseType = 'json')
    {
        $url = config('app.WHMCS_URL').$this->suffix;

        $data['username'] = $this->identifier;
        $data['password'] = $this->secret;
        $data['responseType'] = $responseType;
        $data['action'] = $action;
        // dd($data);
      $response = HTTP::withBasicAuth(config('app.BASIC_AUTH_USR'), config('app.BASIC_AUTH_PWD'))->withHeaders([
            'Content-Type' => 'multipart/form-data',
            'Accept' => '*/*'
        ])->post($url, $data);

        dd($response->body()); // "result=error;message=Authentication Failed"
        return ;
    }

The same exact keys work in postman. I'm stuck, am missing anything?

If you're using API keys and not users, change username to identifier and password to secret per https://developers.whmcs.com/api/authentication/

 Hi, 

I noticed that there are several posts here regarding sending API commands using postman - But I couldn't find an answer here  also in this post or any other.   

I know that in order to send API command to WHMCS I should authenticate using  identifier, secret and an accesskey - But when I'm trying to use them in posman I'm getting `result=error;message=Authentication Failed` error.

I have no problem sending API commands via integromat using the same information.

this is an example for the raw body I'm sending  as a GET request to my /includes/api.php  address:

{
    "action": "GetTicket",
    "identifier": "XXXXXXX",
    "secret": "YYYYYY",
    "accesskey": "ZZZZZZZ",
    "responsetype": "json",
    "ticketid": "1234"
}

 

In my WHMCS  I've setup the API_Authentication_Credentials (So I have the relevant identifier and secret) and also added the relevant accesskey to my configuration.php - But still the same error.
Maybe I should configure some authorization in postman? 
Can someone please help?

Thanks!
