How can I upload a JSON file at the root of my site for external verification

I’m using a third party service that requires me to verify my site with a JSON file (it is Apple app site association).
I have to host this file at http://my-website.domain/apple-app-site-association.json
I can’t use domain CNAME or TXT records.

Any options to do this on webflow ?
Thanks a loooot in advance!

Is uploading JSON file only option there? If it is then you cannot.

If there is option to verify using CNAME or TXT then you can point you domain using something like Cloudflare and there you can update your CNAME or TXT

See /.well-known/ for Apple and Google (JSON)
