Hello, what secondary API PHP code do you mean? And does that mean it can’t work without additional PHP?

Before that, I used this

add_filter( 'pre_http_request', function( $pre, $args, $url ) {
    // Check for GeneratePress URLs
    if ( 'https://generatepress.com' === $url || 'https://generatepress.com/' === $url ) {
        return wp_remote_post(
            'https://api.generatepress.com',
            array(
                'timeout' => $args['timeout'],
                'sslverify' => $args['sslverify'],
                'body' => $args['body'],
            )
        );
    }
    
    // Check for GenerateBlocks URLs
    if ( 'https://generateblocks.com' === $url || 'https://generateblocks.com/' === $url ) {
        return wp_remote_post(
            'https://api.generateblocks.com',
            array(
                'timeout' => $args['timeout'],
                'sslverify' => $args['sslverify'],
                'body' => $args['body'],
            )
        );
    }
    
    return $pre;
}, 10, 3 );

Yes, it works with the code. I was just wondering if there was a way to make it work without the code.
