How the resolver works

A scan hits paqlink.com/01/<gtin>, we look up your record and redirect in under a second.

Every code encodes a GS1 Digital Link URI on our domain. On a scan the resolver validates the URI (bad check digits get a 400, unknown GTINs a 404), finds your product's record, and issues a 307 redirect to the destination you chose, forwarding any GS1 parameters such as expiry. Apps can ask for the full linkset (RFC 9264) instead of a redirect, and a description file at /.well-known/gs1resolver declares the service.

Records are stored in the resolver's own key-value store, separate from the application database, so scans keep working even while the dashboard is down for maintenance.
