you did not pass the checksum security check in bbb

Question

Referred API documentation of bigbluebutton for create call. My API URL is like this: https://server_name/bigbluebutton/api/create?name=Sample&meetingID=B3XdYtdzdoV1&attendeePW=1234&moderatorPW=2345&checksum=d7b20f96f3616a69ae4a50eb1c0472428283c63a Still it is showing the checksum error. I really have no idea why I am facing this error because according to me everything is correct

    $defaults = array(
        'name' => '',
        'meetingID'=>'',//MeetingId
        'attendeePW'=>'',//pass the attendee(student) password
        'moderatorPW'=>'',//pass the moderator (instructor) password
        'welcome'=>'',
        'maxParticipants'=>'',
        'record'=>false,
        'duration'=>'', //(minutes)
        'meta'=>'',//metavalue
        'allowStartStopRecording'=>false,
        'webcamsOnlyForModerator'=>'',//boolean
        'logo'=>'',//url
        'bannerText'=>'',
        'bannerColor'=>'',
        'copyright'=>'',
        'meta_endCallbackUrl'=>site_url(), //redirect to this site
        'meta_bn-recording-ready-url'=>'',
    );

    $args = array_merge($defaults, $args);
    $salt = $this->get_salt();

$url = $this->get_server().'api/create?'.http_build_query($args); $checksum = sha1('create'.http_build_query($args).$salt);

$bbb_url = $url.'&checksum='.$checksum; $response = wp_remote_get($bbb_url);

when tried print_r($bbb_url); It is showing above url with the error message refer: a link!

when you are creating checksum you need to append your moderator password with the secrete key and then put the query stringin sha1, now it will generate you a checksum — Ali Raza, Aug 04 '20 at 05:30

So, I found the answer by myself. After a lot of hit and trials, it was still showing this error. So I break my parameters and then individually test the values of each parameter. The problem was with my server secret which was not correct. Finally, it is resolved

on your server past this command

bbb-conf --secret

then it will return u sth like this:

URL: http://bbb.example.com/bigbluebutton/
Secret: ECCJZNJWLPEA3YB6Y2LTQGQD3GJZ3F93

Link to the API-Mate:
https://mconf.github.io/api-mate/#server=https://bbb.urserver.com/bigbluebutton/&sharedSecret=ECCJZNJWLPEA3YB6Y2LTQGQD3GJZ3F93

use the git hub link to navigate to a page full of suitable API documents

Thank you, I was able to solve by breaking the parameters and testing the value of each parameter individually. The problem was with my server secret – Diana Aug 27 '20 at 06:44

There should be NO space between API_SECRET= and the actual secret

Thanks for the answer but I already found - " I break my parameters and then individually test the values of each parameter. The problem was with my server secret which was not correct" – Diana Aug 17 '21 at 18:58
