How to get credentials

You need admin access to your Brex account to create a developer token.

1. Open dashboard.brex.com/settings/developer.
2. Create a new API key / developer token.
3. Grant the scopes the agent needs (e.g. read on accounts, transactions, expenses, budgets, users; write on budgets if you want brex_budget_create).
4. Copy the generated token.
