**Description**  
I’m trying to get an oAuth access token from a user, but I keep getting the 403 forbidden error when sending the POST request.

I have followed the tutorial at [https://marketplace.zoom.us/docs/guides/auth/oauth](https://marketplace.zoom.us/docs/guides/auth/oauth) religiously. I have even checked previous threads that talked about this error, but still couldn’t fix it

**How To Reproduce (If applicable)**  
var fetchURL = ‘[https://zoom.us/oauth/token?grant\_type=authorization\_code&code=dHrAQyHrTw\_C1zkc5XgTO-fCRTjmsfWeg&redirect\_uri=http://localhost:3000/](https://zoom.us/oauth/token?grant_type=authorization_code&code=dHrAQyHrTw_C1zkc5XgTO-fCRTjmsfWeg&redirect_uri=http://localhost:3000/)’

const response = await fetch(fetchURL, {method:“POST”, headers{ “Authorization” : "Basic " + encoded\_cred}})

–\> encoded cred is encoded in base64 and contains Client\_ID:Client\_Secret

Please help, thank you.

Hey @po123,

What content type are you setting for your request?

Try setting `"Content-Type": "application/json"` in the header. 🙂

Thanks,  
Tommy

@tommy Hi, thanks for your reply. I tried that, but it’s still returning 403 error. I’m trying to use localhost as the redirect URI, is that potentially a problem?

Here are my headers:  
{method:“POST”, headers:{ “Authorization”:"Basic " + encoded\_cred, “Content-Type”: “application/json”}

Here is the response I received:

Thanks in advance
