Server-to-Server Access Token Expired

API and Webhooks
#1

My server 2 server access token expired recently.

I’m trying to write some PHP code to get a new access token. On this page:

https://marketplace.zoom.us/docs/guides/build/server-to-server-oauth-app/

You say to use this curl command:

curl -X POST -H 'Authorization: Basic Base64Encoder(clientId:clientSecret)' https://zoom.us/oauth/token?grant_type=account_credentials&account_id={accountId}

I’ve tried this but it’s returning a 405 Method Not Allowed error.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, “https://zoom.us/oauth/token?grant_type=account_credentials&account_id=xxxxxxxxxxxxxxxxx”);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// Set the Authorization header
$auth = “Basic Base64Encoder(” . base64_encode(“yyyyyyyyyyyyyyyyyyy:zzzzzzzzzzzzzzzzzzzzzzzzzz”). “)”;
curl_setopt($ch, CURLOPT_HTTPHEADER, array(“Authorization: $auth”));

$output = curl_exec($ch);

curl_close($ch);

echo $output;

What’s the correct way to use php to call your api to get a new server 2 server access token?

I added this to the curl commands:

curl_setopt($ch, CURLOPT_POST, 1);

Now I get this error:
{“status”:false,“errorCode”:-1,“errorMessage”:“Illegal base64 character 28”,“result”:null}

OK… got it working. Hopefully this helps someone:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, “https://zoom.us/oauth/token?grant_type=account_credentials&account_id=XXXXXXXXXXXXXX”);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);

// Set the Authorization header
$auth = "Basic " . base64_encode(“yyyyyyyyyyyyyyyyyy:zzzzzzzzzzzzzzzzzzzzzz”);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(“Authorization: $auth”));

$output = curl_exec($ch);

curl_close($ch);

echo $output;
