X-Forwarded-Host

Hi, @dalejefferson_rnf. Is Dennis’ answer here helpful?

Knowing the current public hostname of a Netlify function

So the hostname of the lambda function is available inside the context object. Here’s an example of how to do it: deploy-id-test/getdeploy.js at master · depadiernos/deploy-id-test · GitHub function extractNetlifySiteFromContext(context) { data = context.clientContext.custom.netlify decoded = JSON.parse(Buffer.from(data, "base64").toString("utf-8")) return decoded } Let me know if that helps.
