Quaderno Expenses API

  title: Quaderno API
  description: >-
    The Quaderno API is a REST API for tax compliance, invoicing, and sales
    tax / VAT automation. It exposes resources with predictable, account-scoped
    URLs and uses standard HTTP features - HTTP Basic Authentication, standard
    methods, and response codes. All requests and responses are JSON, and every
    endpoint path ends in `.json` to indicate JSON serialization.

    The base URL is account-scoped: `https://ACCOUNT_NAME.quadernoapp.com/api`,
    where `ACCOUNT_NAME` is your Quaderno account subdomain. Authenticate with
    your private API key as the HTTP Basic Auth username (any value for the
    password). Sandbox testing is available on a separate sandbox host.

    Core resources include Contacts, Items, Invoices, Credits, Estimates,
    Expenses, Recurring documents, Payments, Transactions, Checkout Sessions,
    Webhooks, and the tax engine (tax rate calculation, tax jurisdictions, tax
    codes, and tax ID validation). Endpoint paths and the account-scoped base
    URL are confirmed against Quaderno's public developer documentation and the
    official quaderno-ruby SDK; request and response bodies are modeled and
    should be verified against the live API reference.
