How do I generate an Apperio API token?

Log in to Apperio, go to your user profile section, and look for API settings or tokens. You can generate a new token there which identifies your organization and user permissions.

Can I see line-item details for an invoice?

Yes, the `get_invoice_details` tool provides full details including line items and spend breakdown for a specific invoice.

What legal matters can I access via the API?

The API tokens inherit the permissions of the user who generated them. You will be able to access the same matters and invoices that you can see when logged into the Apperio platform.
