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.
