Smartsheet app authorization - allow access



Looking for a guidance. As I am developing an application, that updates data to a sheet periodically (every month).

Here, when I send a GET request to, with all required parameters, its redirecting to my app's consent page where I have to click on 'Allow' button to proceed further.

I want to get rid of this consent page because its repetitive. Moreover, I am planning to keep my application as crone job which runs every month once.

Any help on this regard is much appreciated.

Thanks in advance.
