I have created an admin managed app and i am using the local test environment added app with the returned code to call the get token api [https://zoom.us/oauth/token](https://zoom.us/oauth/token)

Here is my example to call using postman.

Header  
Content-Type: x-www-form-urlencoded  
Host: [zoom.us](http://zoom.us)  
Authorization: Basic {code} with the encoded client\_id and client\_secret

Body (x-www-form-urlencoded)  
code = {code} from the add app returned code local test  
grant\_type = authorization\_code  
redirect\_url = my main webpage url

result i get 400 bad request result.  
{  
“reason”: “Invalid client\_id or client\_secret”,  
“error”: “invalid\_client”  
}
