Upcoming HTTP header case changes

What's happening? 

On January 6, 2023, we will perform a messaging release that may cause changes to the letter case of HTTP headers within HTTP responses and callbacks. For instance, the "Content-Type" header may be changed to "content-type.”

What do I need to do?

Please validate that your applications are parsing these headers in a case-insensitive fashion in accordance with RFC 9110.
