PHP Fatal error: Class 'Microsoft\BingAds\Auth\OAuthWebAuthCodeGrant' not found - php

Question

I am trying to install BingAds API and I keep getting the error
PHP Fatal error: Class 'Microsoft\BingAds\Auth\OAuthWebAuthCodeGrant' not found
I checked the composer file it looks OK.
{
"name": "microsoft/bingads",
"description": "This project provides a set of PHP client libraries that make it easy to access Bing Ads service APIs.",
"keywords": [ "php", "bingads", "bing ads", "sdk" ],
"license": "Apache-2.0",
"type": "library",
"homepage": "https://github.com/BingAds/BingAds-PHP-SDK",
"require": {
"php": ">=5.5.17",
"ext-curl": "*",
"ext-openssl": "*",
"ext-soap": "*"
},
"require-dev": {
"ext-curl": "*",
"ext-openssl": "*",
"ext-soap": "*"
},
"autoload": {
"psr-4": {
"Microsoft\\BingAds\\": "src/"
}
},
"authors": [
{
"name": "Microsoft",
"homepage": "https://github.com/BingAds/BingAds-PHP-SDK/graphs/contributors"
}
]
}
Also, the OAuth2Callback.php files look fine I am calling the namespace on the header as use Microsoft\BingAds\Auth\OAuthWebAuthCodeGrant; and later it calls the class OAuthWebAuthCodeGrant() on the line that gives the error.
The file structure is like:
- BingAds-PHP-SDK-master
- - OAuth2Callback.php
- - WebAuthHelper.php
- - composer.json
- - composer.lock
- - /samples
- - /src
- - /vendor
Does anybody have any clues? I am new with namespaces, not completely sure how it works. Thanks!

Answer 1

Can you share more details about OAuth2Callback.php? Have you tried this web app walkthrough? If you are running this locally in a console then I suggest starting with this console walkthrough.

Answer 2

Recently, I downloaded V13 source code from https://github.com/BingAds/BingAds-PHP-SDK, because the command "composer require microsoft/bingads" from the instruction only sending me the V12 not V13.
I got same error: PHP Fatal error: Class 'Microsoft\BingAds\Auth\OAuthWebAuthCodeGrant' not found.
Compared to the composer.json.
in V13:
"autoload": {
"psr-4": {
"Microsoft\BingAds\": "/src/"
}
},
and in v12:
"autoload": {
"psr-4": {
"Microsoft\BingAds\": "src/"
}
},
after updated the path from "/src/" to "src/", ran "composer update" and it works.
