# BankBridge with ChatGPT (Apps SDK)

Updated Apr 23, 2026·2 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](/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.
