Export users to take action after the fact
If you set On collision to Allow + flag instead of Block, acting on a result means acting in your own product, so the export is the handover: suspend the accounts, hold the payouts, or reconcile against your own records.Making it reconcile
Export gives you a row per person. To join those rows to your own users, give us a key going in. On the code path, attach your ownexternal_id when you start the session. On the no-code import, put your columns in the CSV and we keep them on the row: the product’s own example is name,email,last_seen_ip, so the IP you have on file comes back beside the one we saw.
Without either, you are matching on whatever email or phone they gave the check, which holds until somebody used a different address with you than with us. Import what you will want to compare, because you cannot add it afterwards.
