FAQ

Frequently asked questions

How often does Mettle sync to AI assistants?
Synci polls Mettle 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.
Does Mettle support pending transactions?
Yes — Mettle 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.
Are Mettle credit card accounts supported?
Yes — Mettle credit card accounts can be connected and synced to AI assistants alongside your regular accounts.
Is my Mettle login shared with Synci?
No. Synci connects to Mettle through regulated PSD2 APIs, which means authentication happens on Mettle's own login flow. Your bank login credentials are never shared with or stored by Synci.
Which provider does Synci use to connect to Mettle?
Synci currently connects to Mettle through GoCardless, a regulated PSD2 data provider. Providers handle the technical connection to the bank — your login credentials stay between you and Mettle.
