Submit Contact Form 7 data to External API

add_action( 'wpcf7_before_send_mail','blog_cf7_api_sender' );

function blog_cf7_api_sender( $contact_form ) {
$form_id = ( $contact_form )->id();

    if ( $form_id == '02d6ca7') { 
        $submission = WPCF7_Submission::get_instance();
       
       if ( $submission ) {
            $posted_data = $submission->get_current();
    
            $name = $posted_data['client-name'];
            $phone = $posted_data['client-phone'];
            $stream_code = [4yv1];
            $token = [12345];
    
            $url = 'https://coolapi.com';
            
            $args = array(
             'body' => json_encode(array(
                 'name' => $name,
                 'phone' => $phone,
                 'stream_code' => $stream_code,
                 'token' => $token,
                 )
                 'headers' => array(
                 'Authorization' => 'Bearer $token',
                 'Content-Type' => 'application/json',
                )
              
            );
    
            $response = wp_remote_post( $url, $args );
       }
    }

}

I have created a custom plugin within WordPress to POST contact form 7 data to an external API when a client submits their info, I followed a tutorial on YouTube step by step, but nothing is being posted to the API URL. I am not sure if it’s because the coding for contact form 7 is outdated now or if I am possibly using wp_remote_post incorrectly.
