BankBridge with ChatGPT (Apps SDK)

2 min read
Add BankBridge to ChatGPT (Apps SDK) once, then ask it about your real bank accounts, transactions, subscriptions, and investment holdings. Every question live-fetches in real time — nothing is cached. $5/mo per connected bank.

Setup

Paste the config below into App directory. Swap the placeholder key for your real bbk_ key from your dashboard.

1. ChatGPT → Settings → Connectors → Browse
2. Search for 'BankBridge' and click Add
3. OAuth dialog → sign in → Allow

(Requires BankBridge to be approved in the ChatGPT Apps directory.
 Until then, use the Developer Mode path — see the ChatGPT docs.)

The full doc page for ChatGPT (Apps SDK)auto-fills your real key when you’re signed in.

Three prompts to try

  • “List my bank accounts and current balances.”
  • “How much did I spend on food this month?”
  • “What are my recurring subscriptions?”

If it doesn’t work

Check the ChatGPT (Apps SDK) doc page for the Troubleshooting section. 90% of first-time failures are either a missing Bearer prefix (note the space) or a placeholder key that didn’t get replaced with a real one.
