neoo API

The neoo API lets another system work with a company’s books the way a person would in the app: book vendor bills and customer invoices, upload documents for the AI to read, read the ledger, and queue vendor payments.

It is a JSON-over-HTTPS API. Every request is sent to one dataset and authenticated with an API key.

Where to start

  1. Getting started: create a key and make your first call in five minutes.
  2. Core concepts: the handful of ideas every endpoint relies on (datasets, vendor vs customer, drafts vs approved).
  3. Book a vendor bill: the most common integration, step by step.
  4. API reference: every endpoint, field and response, with a built-in console to try calls.

When something goes wrong, Errors explains the status codes and error codes you can get back.
