# BankBridge with ChatGPT (Apps SDK)

Updated Apr 23, 2026·2 min read

Direct answer: 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](/dashboard/settings).

```
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](/docs/chatgpt-apps-sdk) 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](/docs/chatgpt-apps-sdk) 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.
