Create link to allow costumers download invoice without seeing any part of database

I use Airtable Database as a complete solution for e-shop orders; there are sensitive GDPR data as well as prices etc. Is there an option that would allow me to create a link for my customer to be able to download his invoice (attached .pdf file), without being able to see any other data from his record in my database or even other customers records (rest of the database) ? Thank you for any advice … (I use free version, no PRO plan).
