Oauth invalid_request

I’m migrating from JWT to oauth so I created Server-to-Server OAuth app with credentilas and scopes.
Initially no problems but during the last days I had an issue with oauth token.
With these credentials I create tokens in php

$url = 'https://zoom.us/oauth/token';
$data = array(
       'grant_type' => 'client_credentials'
    );
    
    $headers = array(
        'Authorization: Basic '. base64_encode(my_Client_ID:my_Client_secret)
    );
    
    $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($curl);
    
    if(curl_errno($curl)) {
        echo 'Curl error: ' . curl_error($curl);
    }
    
    curl_close($curl);
    
    $data0=json_decode($response, true);

With this token I call some APIs, for example

$url = "https://api.zoom.us/v2/past_meetings/{$meeting_id}/participants";
$curl = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Authorization: Bearer {$access_token}"
));
$response = curl_exec($curl);

or

$url = "https://api.zoom.us/oauth/check_token?access_token={$access_token}";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response);
if (isset($data->error)) {
    print_r($data->error);    
}

The error I get is invalid_request.

I tried also creating a new token with shell but it’s the same.
I tried also with different client ID and secret ID always the same error.
Any ideas?
Can you help me, please?

Thanks

Am I the only one experiencing this problem?

@p.gallo,

Thank you for posting in the Zoom Developer Forum. Can you share screenshot of the message you are seeing ?

Hi
there’s no specific screenshot: the print_r($data->error) line prints out invalid_request

print_r($data); prints
stdClass Object
(
[reason] => Internal Error
[error] => invalid_request
)

Below the code I use for creating and check the token

<?php

	$url = 'https://zoom.us/oauth/token';
	$data = array(
		'grant_type' => 'client_credentials'
	);
	
	$headers = array(
		'Authorization: Basic '. base64_encode('*my_Client_ID*:*my_Client_secret*')
	);
	
	$curl = curl_init();
		curl_setopt($curl, CURLOPT_URL, $url);
		curl_setopt($curl, CURLOPT_POST, 1);
		curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
		curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
	$response = curl_exec($curl);
	
	if(curl_errno($curl)) {
		echo 'Curl error: ' . curl_error($curl);
	}
	
	curl_close($curl);
	
	echo "<pre>";
	print_r($response);
	echo "</pre>";
	
	
	$data0=json_decode($response, true);
	
	
	
	
	$timestamp = time() + 3460;
	$expiration = date('YmdHi', $timestamp);

	$data0['creazione'] = date('YmdHi', time());
	$data0['expiration'] = $expiration;
	$generated_token=$data0['access_token'];
	
	echo "<pre>";
	print_r($data0);
	echo "</pre>";
	
	$generated_token=$data0['access_token'];
	
	echo "<pre>";
	print_r($generated_token);
	echo "</pre>";
	
	
$url = "https://api.zoom.us/oauth/check_token?access_token={$generated_token}";

	echo "<pre>";
	print_r($url);
	echo "</pre>";


$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response);

if (isset($data->error)) {
    echo "Invalid or expired token.\n";
	echo "<h3>";
	print_r($data->error);
	echo "<pre>";
	
	print_r($data);
	echo "</pre></h3>";
	
	
} else {
    echo "Valid token.\n";
}
	

?>

Is there something else I can share with you?
Thanks

Ran into this just this week as we swap over to OAuth.

Your query string needs the following:

  • grant_type = “account_credentials”
  • account_id = “{Account Id in the OAuth App}”

You get an access token that lives for 1 hour, with no refresh token. When you need a new token, you call the endpoint again to fetch a new token.

Server-to-Server OAuth (zoom.us)

Thank you
I’m pretty sure I still miss something because also with accout credentials I got the same error (altough the token is created)

Below the code

<?php

	$url = 'https://zoom.us/oauth/token';
	$data = array(
		'grant_type' => 'account_credentials',
		'account_id' => '*myAccount_id*'
	);
	
	$headers = array(
		'Authorization: Basic '. base64_encode('*my_Client_ID*:*my_Client_secret*')
	);
	
	$curl = curl_init();
		curl_setopt($curl, CURLOPT_URL, $url);
		curl_setopt($curl, CURLOPT_POST, 1);
		curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
		curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
	$response = curl_exec($curl);
	
	if(curl_errno($curl)) {
		echo 'Curl error: ' . curl_error($curl);
	}
	
	curl_close($curl);
	
	echo "<pre>";
	print_r($response);
	echo "</pre>";
	
	
	$data0=json_decode($response, true);
	
	
	
	
	$timestamp = time() + 3460;
	$expiration = date('YmdHi', $timestamp);

	$data0['creazione'] = date('YmdHi', time());
	$data0['expiration'] = $expiration;
	$generated_token=$data0['access_token'];
	
	echo "<pre>";
	print_r($data0);
	echo "</pre>";
	
	$generated_token=$data0['access_token'];
	
	echo "<pre>";
	print_r($generated_token);
	echo "</pre>";
	
	
$url = "https://api.zoom.us/oauth/check_token?access_token={$generated_token}";

	echo "<pre>";
	print_r($url);
	echo "</pre>";


$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response);

if (isset($data->error)) {
    echo "Invalid or expired token.\n";
	echo "<h3>";
	print_r($data->error);
	echo "<pre>";
	
	print_r($data);
	echo "</pre></h3>";
	
	
} else {
    echo "Valid token.\n";
}
	

?>

Thanks again
