Webhook EndPoint is not validatiing

I've been attempting to set up event subscriptions, but I keep encountering an error when trying to validate the endpoint URL. The message I receive is: "URL validation failed. Try again later." This issue has arisen while developing a new application.

    Hi, did you solve the problem?

     

    I have the same issue while integration with make.com.

     

    I have created everything like it is described in the document (-> https://developers.zoom.us/docs/api/rest/webhook-reference/#validate-your-webhook-endpoint). But I don't know where's the problem actual. On Zoom or on make.com site.

     

    What do I have to put as **salt** into the hash-function:

    This is described in the document with "Set your webhook's secret token as the secret (salt)"

    * The Webhook-ID from make.com

    * the secret-Token from Zoom from the feature page

    * the client-secret from the App-credentials page

    If it helps anyone, this is what worked for me using PHP

    $contents = file_get_contents('php://input'); $input = json_decode($contents, TRUE); $plainToken = $input['payload']['plainToken']; $encryptedToken = hash_hmac( 'sha256', $plainToken, '{secret token}', FALSE ); $response = [ 'plainToken' => $plainToken, 'encryptedToken' => $encryptedToken, ]; $responseOutput = json_encode($response); header("Content-Type: application/json; charset=utf-8", TRUE, 200); print $responseOutput;

     

    'secret token' above is  your Zoom API secret token (not client secret)
