Zoom API Oauth | Error: unsupported_grant_type

[Samarth_Opt]

When making request to get Access Token, I'm always getting unsupported_grant_type Error.

Please help me to know where I'm going wrong..

Code: 

  axios.post(
        "https://zoom.us/oauth/token",
        {
         grant_type:'authorization_code',
         code: req.query['code'],
         redirect_uri: '<RedirectUri>'
        },{
        headers:{
        Authorization: 'Basic ' + Buffer.from('<CLIENT_ID>' + ':' +  
                 '<CLIENT_SECRET>').toString('base64'),
       'Content-Type': 'application/x-www-form-urlencoded',
       } 
}).then((rs:any)=>{
   console.log(rs);
})
.catch((err:any)=>{console.log(err);})

Logs:

    data: {
      reason: 'unsupported grant type',
      error: 'unsupported_grant_type'
    }

I'm getting the same grant type error from this call, did you ever figure this out?

Thanks

Hello, I'm experiencing the same issue, did you figure it out ? Thanks

Hi, yes, I got this working, my code looks like the above but it also has a "code_verifier" .

See github.com/zoom/zoomapps-sample-js

So, PKCE ("code_challenge" & "code_verifier") is unavoidable 😕

I was having the same problem. The Zoom official document says Request body, so I was sending the request by transforming the Request body into json. Do not transform into json, but request in the form of form data or request parameters.

This is my java code that matches the content. I still lack a lot.

I realized my mistake. Looking at the header part of the official Zoom document, it says Content-Type: application/x-www-form-urlencoded, but I wrote the request body in the form of application/json, so the problem seems to have occurred.
