Unauthorized: 401. Session not found, when trying to join via API

[Shahzad Hassan]

Hi,

We have recently started working with BBB. We are trying to integrate BBB into our nodejs app.

We are able to do the following 2 steps successfully on API but failing on 3rd step

1 - create a meeting

2- join a meeting and get a successful XML response 

<response>

<returncode>SUCCESS</returncode>

<messageKey>successfullyJoined</messageKey>

<message>You have joined successfully.</message>

<meeting_id>524077515fcfc3c2974c99f7ffefbca3649b9bb6-1581324727543</meeting_id>

<user_id>w_iyguoxf7vlqf</user_id>

<auth_token>aq9nzatnidz0</auth_token>

<session_token>tbmi71sarqykby4g</session_token>

<guestStatus>ALLOW</guestStatus>

<url>https://bbb.schoolx.pk/html5client/join?sessionToken=tbmi71sarqykby4g</url>

</response>

3) When we try to join on the URL in the response we are getting unauthorized 401 (session not found error). We are trying to open the conference into an IFRAME and hiding the URL from end-users.

by the way, it's not clear how to use auth_token here

Please advise if we are doing something wrong.

Hi Shahzad,

 I am also facing the same issue. I also try to find the solution for this. If you have to solve this problem temporarily then you have to refresh the page and try again to join.

This is not the correct solution but I didn't get any answer to my question yet.

I shared the link of my question. Please go through these and if you get any solution please let me know.

Thanks and Regards

Pranav

The join URL should be called from the user's browser. If you call the join URL from the server-side the client won't be able to retrieve the enter API and you'll get a 401.

Hi Shahzad,

I am also facing same issues when I create and join the meeting by APIs. I tried reinstalling it but it is not working. However, when I create meeting with Greenlight client, it works perfectly. I was just wondering if you found any fix for that?

Thanks.

Hi Ashish,

As far as I remember it was some combination of API parameters that were causing this issue. 

With the right combination, it started to work.

Sometimes though we get this error when using Safari. We think it because of slow internet connection. 

If you keep on getting this error, send me your API request and I can match it with mines to see if there are any differences.

Regards,

Hi Shahjad, 

I got it working. For future reference, I am just pasting code with sample API payload here which is written in Laravel. Hope it will be helpful:

<?php

namespace App\Lib;

use Illuminate\Support\Facades\Facade;

use Illuminate\Support\Facades\Http;

class BBBHelper extends Facade

{

/* Example of generating joining Url

$url = BBBHelper::getJoinMeetingUrl([

'fullName' => 'User+653034',

'meetingID' => 'MeSc1EqvKZ',

'password' => 'ar5E',

'redirect' => 'true',

]);

*/

public static function getJoinMeetingUrl($parameters, $debug = false)

{

$paraString = http_build_query($parameters);

if ($debug) print "\n\nParastring: {$paraString}\n";

$checksum = sha1("join".$paraString.env('BBB_SALT'));

return env('BBB_API_URL') . "/join"."?{$paraString}&checksum={$checksum}";

}

/*Example of Creating Meeting

BBBHelper::runAPI('create', [

'name' => 'Ashish-11234',

'meetingID' => 'MeSc1EqvKZ',

'moderatorPW' => 'ar5E',

'attendeePW' => '1234',

'duration' => 60,

'maxParticipants' => 5,

'logoutURL' => 'env("BBB_RETURN_URL")',

'record' => 'false',

'redirect' => 'true',

'allowStartStopRecording' => 'true'

], false);

*/

public static function runAPI($name, $parameters, $debug = true)

{

$paraString = http_build_query($parameters);

if ($debug) print "\n\nParastring: {$paraString}\n";

$checksum = sha1($name.$paraString.env('BBB_SALT'));

if ($debug) print "Checksum: {$checksum}\n";

$url = env('BBB_API_URL') . "/{$name}" ;

$parameters['checksum'] = $checksum;

$response = Http::withOptions(['debug' => $debug])

->get($url, $parameters);

return $response->body();

}

}
