Generate Facebook access token with ads_read – Facebook api

I want to get Facebook statistics about campaigns and ads using the Facebook Ads API (https://github.com/facebook/facebook-php-ads-sdk).

I have created an app (with ID and secret), added the Marketing API and now I can generate an access token with the ads_read permission, which is valid for 2 month.

Is there any way that I can avoid the process of manually clicking that button every other month?

I have tried this call:

$tokenUrl = 'https://graph.facebook.com/v2.8/oauth/access_token?client_id=' . $app_id . '&client_secret=' . $app_secret . '&grant_type=client_credentials&scope=ads_read';

This gives me an access token that look something like this: 680012345678976|aIDrLVvFqHXDzl6538RLUF4S9C4 and it doesn’t work (Unsupported get request).

The manually generated token is 164 chars long.

    You can use the short living token for a long living one (even without expiration) by doing a request from your server

    GET https://graph.facebook.com/oauth/access_token?  
   grant_type=fb_exchange_token&         
   client_id={app-id}&
   client_secret={app-secret}&
   fb_exchange_token={short-lived-token}

    Note that even the token that is set to never expire can be invalidated by user, for example if he changes FB password or removes your app entirely.

    What I did was:

    1.Call

    https://www.facebook.com/v2.8/dialog/oauth?client_id=
<APP_ID>&redirect_uri=<REDIRECT_URI>&scope=ads_read

    then after clicking “Allow”, I would get redirected to

    <REDIRECT_URI>/?code=<AUTHORIZED_CODE>

    2.Exchange the authorized code for access token

    https://graph.facebook.com/v2.8/oauth/access_token?client_id=<APP_ID>&redirect_uri=<REDIRECT_URI>&client_secret=<CLIENT_SECRET>&code=<AUTHORIZED_CODE>

    your redirect uri should ends with / e.g. http://localhost:3000/

    I tried this by manually copied and pasted in a browser, but automate request/response should give the same result.
