FAQ
Questions, answered.
Synci polls American Express for new data every 30 to 360 minutes, depending on your plan. Some banks may not support high-frequency sync (30 min). When new transactions or balance changes are found, they are transferred to AI assistants within seconds.
Yes — American Express exposes pending transactions, and Synci syncs them to AI assistants. When the bank eventually books them, Synci automatically updates the same transactions in AI assistants rather than creating duplicates.
When you first connect American Express, Synci can import up to 90 days of transaction history into AI assistants. From that point on, new transactions and balance changes are synced continuously.
Yes — American Express credit card accounts can be connected and synced to AI assistants alongside your regular accounts.
No. Synci connects to American Express through regulated PSD2 APIs, which means authentication happens on American Express's own login flow. Your bank login credentials are never shared with or stored by Synci.
Synci currently connects to American Express through GoCardless, a regulated PSD2 data provider. Providers handle the technical connection to the bank — your login credentials stay between you and American Express.
