How to add custom headers in the proxy RESPONSE?

[Classic298]

Basically as the title says.

After LiteLLM proxy has successfully handled a request, the response should contain custom headers with custom values.

I am thinking of custom callbacks to handle this?
But I am not sure custom callbacks are capable of doing this.

I also could not find anything in the docs.

Does anyone know?

Use post call hooks - https://docs.litellm.ai/docs/proxy/call_hooks
