Hi there,

I am trying to use Postman to test the Zoom API. Since Zoom can only create one JWT app per account, I believe it will be better to use OAuth app to test instead, so that if there are other developers who wanna test it, they can create their own tokens.

Then I try to follow the guide here.

[https://marketplace.zoom.us/docs/api-reference/using-zoom-apis](https://marketplace.zoom.us/docs/api-reference/using-zoom-apis)  
To be specific, the “Authorization Code” section.

I can successfully retrieve the authorization code, but failed to create the token using the following CURL. Please help

curl --location --request POST ‘[https://api.zoom.us/v2/oauth/token?grant\_type=authorization\_code&code=](https://api.zoom.us/v2/oauth/token?grant_type=authorization_code&code=)\<authorization\_code\_received\_from\_redirect\_url\>&redirect\_uri=https://\<blah\_blah\>’   
–header ‘Authorization: Basic \<app\_client\_id:app\_client\_secret\_in\_base64\>’

Request returned 401

{  
“code”: 124,  
“message”: “Invalid access token.”  
}

Hey @vicker, thanks for posting and using Zoom!

You installed / authorized the OAuth app correct?

Can you try following the steps here:

Thanks,

Hi @tommy,

It works great, thank you. I notice what I’ve done wrong as well. The endpoint I used is  
v2/oauth/token instead of  
oauth/token

Though it’s interesting that the v2 one also provide a response.

Hey @vicker,

I am glad you were able to resolve your issue! 🙂

Yes, for the oauth endpoints, the url does not include the `v2` path.

Thanks,  
Tommy
