How can I check budgets of connected apps

Every time you connect your Hub to another application, you can set a budget of how much you want to spend that specific app. That's another security measure to avoid overspending and potential draining of your funds by the connected app. If you trust the app you can also set an “unlimited” budget. As a consequence you don't have to regularly check if you are still within your planned budget.

If you want to increase or decrease your budget, you can just navigate to 'Connections', click on the relevant app, select 'Edit' and change the budget accordingly.
