Hi, thanks for your comment/suggestion.

However, 404 error code (and subcodes) means the resource cannot be found or is deleted, and this is not the case when a profile picture cannot be displayed due to whatsapp privacy settings. There is no 404 subcode that matches the privacy settings case: https://en.wikipedia.org/wiki/HTTP_404

If you need a custom response, please send an email to info@inutil.info with your use-case, and we can provide a custom endpoint including the custimized error codes adjusted to your needs.

Best regards.
