# Dolfin API is live

> Accounts receivable, invoicing, and the AR Agent are now available through the Dolfin API.

<Update label="2026-04-14" description="API launch" tags={["Feature", "Release"]}>
  ## AR Agent

  You can now create customers, products, and invoices through natural language using the [AR Agent](/guides/quick-start-ar-agent). Send a conversation to `POST /agent/ar` and the agent handles the rest — no need to call individual endpoints.

  ## Invoicing API

  The full invoicing lifecycle is available via the API. You can [create invoices](/guides/quick-start-ar), attach line items, generate PDFs, and send them to your customers — all in four API calls.

  ## Client integration

  A complete [onboarding flow](/guides/client-integration) for platforms embedding Dolfin. Your backend provisions organisations and users, generates short-lived auth codes, and your users exchange them for session tokens to interact with the API directly from the browser.

  ## Organisation and user management

  Create and manage organisations and users through the API. Provision new organisations, update their details, and add users with scoped roles — all from your backend.

  ## Multi-currency support

  Manage currencies for your organisations. Enable currencies from the available list, view active currencies, and disable ones you no longer need.

  ## Customer, product, and tax rate management

  Full CRUD endpoints for [customers](/guides/quick-start-ar#step-1-create-a-customer), [products](/guides/quick-start-ar#step-2-create-a-product), and tax rates. Define your catalog and billing data before creating invoices.

  ## Dual authentication

  Two authentication methods are available. Use [API key authentication](/guides/authentication) for server-to-server calls, or [Bearer tokens](/guides/client-integration) for browser-to-API access. Bearer tokens are valid for 8 hours after exchanging a short-lived auth code.

  ## Sandbox environment

  A sandbox environment is now available for testing your integration with no real-world consequences. Contact [hello@dolfinai.co](mailto:hello@dolfinai.co) to get access.
