Is Capital One supported?

Yes. Capital One connects securely through Plaid, so you can link your accounts and start syncing in minutes.

How often does Capital One sync to Airtable?

Syncs are event-driven: Plaid notifies Redbark when new Capital One data is available, and your Airtable updates soon after, typically within a few hours of a transaction posting.

Is my Capital One connection read-only?

Yes. Plaid connections are read-only. Redbark can read transactions and balances, and can never move money or change your Capital One accounts.

Does Redbark store my Capital One data?

No. Redbark uses a pass-through architecture: your Capital One transactions are proxied live to Airtable. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

Do I have to give Redbark access to my whole Airtable account?

No. Airtable lets you grant access to only the bases you choose during authorisation. Redbark can only read and write the bases you share with it.

Will my Airtable views and automations keep working?

Yes. Redbark only creates and updates transaction records. Any views, interfaces, formulas or automations you build on top keep working as the data grows.

Get started

Sync Capital One to Airtable in three steps

Connect Capital One

Link your Capital One accounts through Plaid. You consent at your bank, and Redbark never sees your login.

Connect Airtable

Authorise Redbark, choose the base you want to use, then pick a table (or have Redbark create a Transactions table).

Watch it sync

The transaction fields are created automatically on the first run. After that, new Capital One transactions appear as records within hours of posting.
