如何在PHP中通过Linkedin API v2在Linkedin公司页面上发布

我在LinkedIn上创建了一个个人帐户，后来我用相同的个人ID创建了一个公司页面。我想用php创建自动调度程序，这样我就可以在公司页面上发布一些内容

我已经在LinkedIn开发者部分创建了这个应用程序，并且批准了它。我显示该应用程序具有以下权限

r_emailaddress
r_basicprofile
w_member_social
w_organization_social
rw_organization_admin

我已经为linkedin创建了一个Oauth，我获得了访问令牌，在获得访问令牌后，我获得了我的linkedin ID，然后我尝试通过API在linkedin上发布内容

当我提出发帖请求时，它会在个人资料上发帖，而不是在它管理的公司页面上

下面是我的配置文件

<?php
        define('CLIENT_ID', 'ID_HERE');
        define('CLIENT_SECRET', 'SECRET_HERE');
        define('REDIRECT_URI', 'call_back_url_here');
        define('SCOPES', 'r_emailaddress,r_basicprofile,w_member_social,w_organization_social,rw_organization_admin');
?>

}
