What Well does with your American Express connection
Connect
Connect American Express over Plaid: you authenticate with American Express through Plaid's secure connection, so your bank login never reaches Well; Well holds only a read-only connection it cannot use to move money.
Sync
Well brings account, transaction, and balance in from American Express on a recurring poll that fetches only what changed since the last read. The first sync backfills history in the background and the connection stays live after.
Enrich
Well resolves each American Express entity into workspace account, bank transaction, and cash position, assigns categories, and links every record to an audit trail across the rest of your connected tools.
Available
Your data from American Express lands in the workspace as workspace account, bank transaction, and cash position you can search, chart, and automate.

Frequently asked questions about American Express and Well
How do I connect American Express to Well, and how long does it take?
From Well, open Connections, find American Express, and click Connect. Well links American Express through Plaid: you authenticate on American Express's side in Plaid's secure flow, and Well receives a read-only connection. Your American Express login never reaches Well. The handshake takes about a minute, and Well starts importing accounts, balances, and transactions right after.
What does Well pull into the workspace from American Express?
Well brings in account, transaction, and balance from American Express and reshapes each entity into your workspace: account becomes workspace account; transaction becomes bank transaction. Every record arrives with the source identifier preserved, so American Express stays the source of truth while Well lets you query the data alongside the rest of your stack.
What does American Express unlock once it is connected to Well?
Once American Express is connected, every record it exposes is queryable from conversation, filterable in records tables, and available to your agents through your workspace. The data stays linked to its American Express source, so you can always trace a workspace record back to the original.
How does Well match an account from American Express to a workspace account in my workspace?
Each American Express account is scored against the candidate workspace accounts in your workspace on identifier overlap, amount or quantity match, date proximity, and counterparty resolution. Matches above the auto-link confidence threshold flow through cleanly; below the threshold they queue for a one-click human review, with the most likely workspace account prefilled and the American Express source attached.
How often does American Express sync with Well, and what triggers a refresh?
Well polls American Express regularly for account, transaction, and balance. The first connect pulls the historical window your account allows; subsequent reads only fetch what changed since the last sync, so the load on American Express's side stays modest.
Can I disconnect American Express and what happens to the data Well already pulled?
Open Connections > American Express in Well and click Disconnect. Well drops the Plaid connection immediately and stops reading from American Express; you can also revoke Well from your Plaid dashboard. The account, transaction, and balance Well already imported stay in your workspace by default; ask Support to purge them if your compliance flow requires it.
What is American Express's routing number?
American Express's ACH routing numbers are 124085066 and 124303243. You never enter it by hand in Well, the connection runs through Plaid where you authenticate on American Express's side, and the routing number is shown here as a reference.
Which region does American Express cover in Well?
American Express is a US institution, connected through Plaid. Well reads its accounts, balances, and transactions as a read-only feed and never moves money or changes anything at American Express.
