Unable to get OAuth 2.0 refresh_token with GetRefreshToken.php
Mark
Having used the adwords API for some years and upgraded various versions of the PHP client library including the apility days, we are having major problems with a migration from v201209 to v201306
Our use is solely to run our own adwords account by automatically changing adverts prices, adding new adgroups and keyword for new products.
Currently we maintain some 13K + adgroups.
We use the PHP client library as the base of our development for authentication, updating and communication included from within our own scripts which communicate directly with our database servers.
As you can imagine as we have been offline since the sunset of v201209 this is now critical.
Currently, we have downloaded the v201306 php client library and uploaded it to a test area on our server.
We have followed the instructions about getting an OAuth 2.0 refresh_token and that is where we have hit a brick wall.
We have the client_id, client_secret both of which have been placed into the src/Google/Api/Ads/Adword/auth.ini file.
The next step was to run GetRefreshToken.php
We have ran this from [url]/examples/AdWords/Auth/GetRefreshToken.php and initially ended up with a blank page.
Some debug later and we found that the command:
if (__FILE__ != realpath($_SERVER['PHP_SELF'])) {
return;
}
the realpath command is returning false and therefore the two values did not match and consequently the script was just stopping without any message hence the white screen.
So we commented out these commands and tried again. This time we got a little further but still received an error.
Log in to your AdWords account and open the following URL:
https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=[REMOVED].apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fadwords.google.com%2Fapi%2Fadwords%2F&access_type=offline
After approving the token enter the authorization code here:
Your OAuth2 Credentials are incorrect.
Please see the GetRefreshToken.php example.
{
"error" : "invalid_request"
}
Even with the error, we tried to use the url by manually posting it in a browser but that give us an error that the url was incorrect.
Having trolled through many forum and web posts we are still no further forward as to what could be the problem.
Any assistance to just get past this first step of getting a refresh_token would be appreciated
