How do I manipulate requests and response headers in AWS Api Gatway using Lambda?

I want to create an API Gateway HTTP integration (reverse proxy) but manipulate the header and response headers.

I know that I can use template mappings but this only supports very simple replace functionality.

For my project I need to do a database lookup to fill in a certain request header. Ideally a Lambda function would do this but I can not see a way to use a Lambda function to manipulate headers in combination with the HTTP integration.

The only other option I see is to use Lambda integration and create a whole reverse proxy integration myself in this Lambda. I would like to avoid this.

Any options someone can think off?

You can front your API gateway with CloudFront. This allows you to manipulate http requests before they reach your API through CloudFront function or lambda@edge. Both of them can be lambda functions.
