What Well does with your Capital One connection
Connect
Connect Capital One over Plaid: you authenticate with Capital One 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 Capital One 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 Capital One 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 Capital One lands in the workspace as workspace account, bank transaction, and cash position you can search, chart, and automate.
Questions Capital One unlocks
Ask in plain language. Well answers from your connected Capital One connection, resolved against the rest of your stack.

Well can read your accounts, balances, and transactions, but cannot move money, initiate a payment, or change anything at Capital One. Disconnect any time from Well or your Plaid dashboard.

Frequently asked questions about Capital One and Well
How do I connect Capital One to Well, and how long does it take?
From Well, open Connections, find Capital One, and click Connect. Well links Capital One through Plaid: you authenticate on Capital One's side in Plaid's secure flow, and Well receives a read-only connection. Your Capital One 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 Capital One?
Well brings in account, transaction, and balance from Capital One and reshapes each entity into your workspace: account becomes workspace account; transaction becomes bank transaction. Every record arrives with the source identifier preserved, so Capital One stays the source of truth while Well lets you query the data alongside the rest of your stack.
What does Capital One unlock once it is connected to Well?
Once Capital One 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 Capital One source, so you can always trace a workspace record back to the original.
How does Well match an account from Capital One to a workspace account in my workspace?
Each Capital One 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 Capital One source attached.
How often does Capital One sync with Well, and what triggers a refresh?
Well polls Capital One 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 Capital One's side stays modest.
Can I disconnect Capital One and what happens to the data Well already pulled?
Open Connections > Capital One in Well and click Disconnect. Well drops the Plaid connection immediately and stops reading from Capital One; 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.
