You can now use request and response policies to transform the headers and query parameters of incoming requests, and the headers of outgoing responses.

Using an API gateway, you can now:
• Add, remove, and modify headers in requests and responses.
• Add, remove, and modify query parameters in requests.
• Rewrite request URLs from a public format to an internal format, perhaps to support legacy applications and migrations.
