Question

Hi,

My code was working fine. I started to get this error after refreshing:

Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: POST https://login.microsoftonline.com/common/oauth2/v2.0/token resulted in a 400 Bad Request response: {"error":"invalid_grant","error_description":"AADSTS54005: OAuth2 Authorization code was already redeemed, please retry (truncated...) in C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\guzzle\src\Exception\RequestException.php:113 Stack trace: #0 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\guzzle\src\Middleware.php(69): GuzzleHttp\Exception\RequestException::create(Object(GuzzleHttp\Psr7\Request), Object(GuzzleHttp\Psr7\Response), NULL, Array, NULL) #1 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(204): GuzzleHttp\Middleware::GuzzleHttp{closure}(Object(GuzzleHttp\Psr7\Response)) #2 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(153): GuzzleHttp\Promise\Promise::callHandler(1, Object(GuzzleHttp\Psr7\Response), NULL) #3 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\TaskQueue.php(48): GuzzleHttp\Promise\Promise::GuzzleHttp\Promise{closure}() #4 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(248): GuzzleHttp\Promise\TaskQueue->run(true) #5 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(224): GuzzleHttp\Promise\Promise->invokeWaitFn() #6 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(269): GuzzleHttp\Promise\Promise->waitIfPending() #7 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(226): GuzzleHttp\Promise\Promise->invokeWaitList() #8 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\promises\src\Promise.php(62): GuzzleHttp\Promise\Promise->waitIfPending() #9 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\guzzle\src\Client.php(187): GuzzleHttp\Promise\Promise->wait() #10 C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\guzzle\src\ClientTrait.php(95): GuzzleHttp\Client->request('POST', 'https://login.m...', Array) #11 C:\xampp\htdocs\SbcertAudit\vendor\adnanhussainturki\microsoft-api-php\src\Auth.php(98): GuzzleHttp\Client->post('https://login.m...', Array) #12 C:\xampp\htdocs\SbcertAudit\callback.php(52): myPHPnotes\Microsoft\Auth->getToken('0.AXQAPJzrZ27Gy...', '161903') #13 {main} thrown in C:\xampp\htdocs\SbcertAudit\vendor\guzzlehttp\guzzle\src\Exception\RequestException.php on line 113

Using: Microsoft API PHP Wrapper

Any ideas?

Answer 1

This is a very common error. The authorization code cannot be redeemed for the access token multiple times, and it will become invalid after it is used once. You only need to run your authorization URL again and log in to the user to get a new authorization code.
