since YouTube v2 API is becoming obsolete I need to upgrade to v3.
With v2, I also used the legacy ClientLogin verification method ( http://bit.ly/v2_ClientLogin_authentification ) to authenticate and then upload custom videos to my YouTube channel.
With v3, I tried to authenticate using a service account with the same codebase as here.
PHP Youtube API v3 - Direct Download - Unauthorized Message
and I get the same error message from the API endpoint:
Error while calling POST https://www.googleapis.com/youtube/v3/videos?part=status%2Csnippet : (401) Unauthorized
I also verified through Google tokeninfo ( https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=[ACCESS_TOKEN] ) that the access token is valid:
{ "issued_to": "***.apps.googleusercontent.com", "audience": "***.apps.googleusercontent.com", "scope": "https://www.googleapis.com/auth/youtube", "expires_in": 3592, "access_type": "offline" }
All YouTube examples I found are based on OAuth2 and user authorization. (e.g. here: http://bit.ly/yt-api-example-videoupload ). But this is not the way I want: the user should not see "Please authorize what.de to upload videos to YouTube" And the videos should be uploaded to my YT channel instead of them.
If there is no way to use the API service account for this, could you give me a hint how to do this with OAuth2? :-)
Here is my current code:
/** Config */ $private_key_password = 'notasecret'; $private_key_file = '***.p12'; $applicationName = '***'; $client_secret = '***'; // <--- WHERE IS THAT CLIENT_SECRET COMING FROM?

' uploaded <br/>'; $cont++; } fclose($handle); echo '<br/>OK<br/>'; } else { // @TODO Log error echo 'Problems creating the client'; } } catch(Google_Service_Exception $e) { print "Caught Google service Exception ".$e->getCode(). " message is <br>".$e->getMessage(). " <br>"; //print "Stack trace is ".$e->getTraceAsString(); } catch (Exception $e) { echo $e->getMessage(); } ?>
