Transactions and Webhooks after Auth Update #42140 Jan 30, 2018 RESOLVED

David Selassie Jan 25, 2018

When a Plaid Item needs an auth update, it seems like Plaid can't access new txn or balance data for that Item.

When the Link UI finishes an auth update, will we soon receive webhooks for txns that were made during the window when the auth was invalid and Plaid didn't have access?

E.g. Customer changes their bank password on Jan 1st. They make a purchase from that bank account on Jan 2nd; we won't get a webhook for that then because Plaid can't get new data. On Jan 3rd, they go through the Link auth update. Will we get a webhook for the txn on Jan 2nd, but delivered on the 3rd?

Is there any delay between when the auth update is completed in the Link UI and when our backend can query for transactions during the time window when the auth was invalid?
