Date Updated: 3/6/2020

← Back to Hosted iFrame Tokenizer Changelog

The following updates have been deployed only to the UAT environment on 3/6/2020, and will be deployed to the production environment at a future date.

URL Parameter Validation

This update includes additional validation to ensure that integrated iFrames are coded following standard best practices. Specifically, it is important that all special characters (including curly braces {} )provided within the iFrame URL parameters are properly URL-encoded, as described in iFrame Styling.

Failure to properly encode the URL string will result in iFrame display and rendering issues.

Additional CSS Support

The css parameter now supports custom colors for placeholder text, as well accepting CSS3 media queries for responsive design.

All arguments to the css parameter must be URL-encoded.
