Description
My goal is to pull all of our assigned phone numbers within our Zoom account. To do so via the API, I am trying to receive an access token by making a POST request https://zoom.us/oauth/token. I am following the steps within this documentation page: https://marketplace.zoom.us/docs/guides/auth/oauth

Error
I am receiving the following issue

{

"reason": "Invalid client_id or client_secret",
"error": "invalid_client"

}

Which App Type (OAuth / Chatbot / JWT / Webhook)?
The App Type is OAuth

Hey @william_williams2,

Happy to help!

In taking a quick look, it appears you’re passing the Authorization as a query parameter instead of as a header. Can you please ensure you’re sending it in the header? Here is an example in cURL:

var client = new RestClient("https://zoom.us/oauth/token?grant_type=authorization_code&code=code&redirect_uri=https://zoom.us");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization", "Basic Q2xpZW50IElEOkNsaWVudCBTZWNyZXQ=");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

That was a complete mistake on my part and it looks like I’m all set! I just had to include the grant type since I was using client credentials, but that was an easy one to troubleshoot.

Thanks!
