I'm integrating a Southeast Asian API into my app.

API: FreshBooks Accounting API ~ invoicing, expenses & accounting
Provider: FreshBooks
Auth: requires OAuth credentials (sign up: https://www.freshbooks.com/api/start)
Pricing: freemium
Base URL: https://api.freshbooks.com
Important note: OAuth2 REST API for invoices, expenses, clients, payments and accounting for small-business/freelancer books. Global, works for MY.

Source: FreshBooks (https://www.freshbooks.com/api/start)
Source type: Provider API or developer docs
Endpoint type: Provider API base URL
Integration difficulty: Needs OAuth
Last checked: 2026-06-29
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
