Hello.
We have been using the AdWords API for months, and implemented an OAuth
login feature months ago. We were using it until 2 days ago, but suddenly
we started getting the "invalid request" error, which is as follows:
OAuth2Exception in
googleads-php-lib/src/Google/Api/Ads/Common/Util/SimpleOAuth2Handler.php
line 119:{
"error" : "invalid_request"
}
I tried with different client ID and secret couples, but got the same
error. I also tried the example codes which are called *GetRefreshToken.php
*and *GetRefreshTokenWithoutIniFile.php* from the
*googleads\googleads-php-lib\examples\AdWords\Auth\* path. I tried
different things but unable to authenticate myself as the API client.
I am using the following piece of code, where I get the error in the last
line:
$user = new AdWordsUser();
$user->SetDeveloperToken(env('DEVELOPER_TOKEN'));
$user->SetUserAgent(env("USER_AGENT"));
$OAuth2Handler = $user->GetOAuth2Handler();
$credentials = $OAuth2Handler->GetAccessToken($this->clientCredentials,
$authCode, $this->callbackUrl);
The variable "clientCredentials" contains my client ID and client Secret,
"authCode" is the authentication code that came as the parameter to the
callback URL, and callback URL is my callback URL. I have been using this
setup for more than 3 months, but for the last 2 days it constantly gives
me the "invalid request" error.
Thanks for any help. I can provide more details if you want.
