I have a google cloud API function that is built on Node.js. I want to find the source of API request. I mean request header referer. I have tried using req.get('referer') but that was returning null. Can I access this information in any other way? Please help

It is not unexpected for the referrer to sometimes be null (or always, in the case of all requests coming in from a client that doesn't send one) – Kevin B Jul 14 '22 at 18:04

Doing a quick test for the same situation you're handling, it works without any issue.
It was tested with: curl “<FUNCTION_ URL>” --referer "https://google.com"
And to get the request header, I used: req.get(‘Referrer’)
Have in mind that if the URL is not valid, the result would be undefined, as follows:
If the solution provided still does not work, it might be an issue with your request to Cloud Functions.
