API capability pack for bounded FreshBooks REST operations against https://api.freshbooks.com only. Reads the authenticated identity, clients, invoices, payments, estimates, expenses, projects, services, and time entries for daily solo-business accounting and time tracking. Writes cover approval-gated client upkeep, invoice draft/update/send actions, estimate draft/update actions, expense logging, and time-entry creation/update using FreshBooks' documented request wrappers. Enroll a FreshBooks OAuth bearer-token connection named freshbooks; no credential is embedded in the manifest. FreshBooks uses account_id for accounting endpoints and business_id for projects, services, and time tracking; both are discoverable from the identity endpoint. The pack intentionally excludes deletes, payment mutation/collection flows, online payment setup, invoice/estimate attachments, project/service mutation, reports, staff/admin settings, webhooks, arbitrary API passthrough, and any endpoint outside api.freshbooks.com.
