Hi @ricardo.cadena1991,

It should be possible to retrieve an access\_token via API.

After you’ve installed the OAuth App locally, it will take you to your redirect URL and a `code` parameter will be appended in the browser URL (this is a manual step).

Once you have that code, you need to send a request to our OAuth endpoint following this format:  
`https://zoom.us/oauth/token?grant_type=authorization_code&code={code}&redirect_uri={redirectUri}`

Can you ensure you’re following the steps outlined [here](https://marketplace.zoom.us/docs/guides/auth/oauth)? Please also double check you’re passing the grant\_type parameter above.

Thanks!  
Will
