Service URL cannot be longer than 128 characters...

Service URL path field length is limited to 128 characters. When attempting to save a service's settings with a URL longer than 128 characters, it gets trimmed. At admin/config/services/wsclient/manage/{service}

Can '#maxlength' be more than 128 characters?

  $form['url'] = array(
    '#type' => 'textfield',
    '#title' => 'URL',
    '#maxlength' => 4096, // <-- This needs to be much bigger than the default of 128 chars.
    '#default_value' => $service->url,
    '#required' => TRUE,
    '#description' => t('The URL of the web service.'),
    '#element_validate' => array('wsclient_ui_element_url_validate'),
  );
