JSON – Passing a query

Hi @logicred

You should be able to write some custom code that uses the http_api_curl() hook to do this. Here’s an untested example that you can modify as needed:

// POST parameters when fetching feed
add_action( 'http_api_curl', 'my_curl_set_opts', 10, 3 );

function my_curl_set_opts( $handle, $r, $url ) {
    if ( $url == 'https://example.com/jsonfeed' ) {
        $data = array(
            'client'            => 'CUSTOMER CODE',
            'login'             => 'LOGIN',
            'pass'              => 'PASSWORD'
        );

        $post_params = '';
        foreach ( $data as $pn => $pv ) {
            $post_params .= ( $post_params == '' ? '' : '&' ) . $pn . '=' . urlencode( $pv );
        }
        curl_setopt( $handle, CURLOPT_POST, true );
        curl_setopt( $handle, CURLOPT_POSTFIELDS, $post_params );
        curl_setopt( $handle, CURLOPT_RETURNTRANSFER, true );
        // Optional below (disable host/peer verification in case of SSL errors)
        // curl_setopt( $handle, CURLOPT_SSL_VERIFYPEER, false );
        // curl_setopt( $handle, CURLOPT_SSL_VERIFYHOST, 0 );
    }
}
