Does the library you are using support putting a custom client? I was trying to do some response rewrite for the library InstructorLite that is using req, so I add something like
defmodule MyClient do
def post(url, opts) do
case Req.post(url, opts) do
... rewrite response
... you can get the pid here I guess
and set the custom client option adapter_context: [http_client: MyClient,
