I am building an app in which we sell products on third party marketplaces like OfferUp and Ebay.
We want to incorporate the purchase of an item with a verification process so that our users can sign into our interactive app.
If I wanted to relate a purchase to the email provided to us by our consumer, how could I ensure that their email will properly relate itself to the item if their email is encrypted when they sign in?
Here’s how I’ve structured the work flow:
1.) Person buys a kit on third part marketplace.
2.) We send an email with the verification ID and a CTA for them to join the app.
3.) After downloading the app and they sign in by pressing a login in button on the welcome page.
4.) Once a user is signed they are prompted to enter the verification ID (Row ID)
5.) If the Entered ID matches a lookup value (related by matching email address), then authorize.
6.) Authorized user, has access to dashboard, personal tracking system, and other features.
With this new change to hiding user email addresses, I am not sure if this workflow will function properly.
P.S. I would like to keep the app on a free plan until proof of concept.
