I proceed with OAuth like in examples but I get some weird behaviour when I come back after 24 hours and test again.

So in general I got one class which invokes all needed OAuth code.

So all of those return success == 1
$success = $client->Initialize();
if ($success) {
$success = $client->Process();
if ($success) {

and then later:
case "Google":
$success = $client->CallAPI(
'GET', array(), array('FailOnAccessError'=>true), $user);

So all client_id, client_secret, scopre is set up correctly prevoiusly but CallAPI return some error in log:
[...] the access token is not set to a valid value [...]

When I try to debug ( and uncoment die statement then it says success:1 and next refresh with uncomenting die gives normal behaviour ( api call retrieves data )

Any idea what I'm doing wrong ?

By default, the class stores tokens in session variables.

If you come in another day after having closed your browser, the original session is gone, so it is not possible to recover the original token.

To preserve tokens for a longer time, you need to use the mysqli_oauth_client.php or something similar that stores tokens in a database.

If you are storing the access token by yourself in a database, keep in mind that you also need to save and restore the expiry time and the refresh token values, so the class can renew expired tokens.

Also read this article if you want to access the API when the user is not present.

Thanks for advice. I've solved problem. It was because during re factoring of my class that wraps oauth client I removed

if ($this->exit)

Those 2 lines seems to be crucial for that narrow case
