MYOB dominates the accounting software market in Australia and New Zealand. If your SaaS product serves businesses in the ANZ region, your customers are probably asking for MYOB integration. This guide covers authentication (including the changes MYOB introduced in March 2025), the ongoing deprecation of AccountRight Classic, and the practical details of working with the API.
If you'd rather skip the complexity of building direct integrations, Apideck offers a MYOB connector through our Unified Accounting API that handles OAuth, token management, and data normalization across MYOB and 30+ other accounting platforms.
What is the MYOB Business API?
The MYOB Business API is a REST-based JSON API for reading and writing data from MYOB AccountRight and MYOB Business company files. It works with both local desktop installations and cloud-hosted files, though the authentication flow differs between the two.
The API covers core accounting functions: contacts (customers, suppliers, employees), invoices, bills, payments, inventory, general ledger accounts, journal entries, tax codes, and payroll. It uses OAuth 2.0 for cloud file authentication and supports OData query parameters for filtering and sorting results.
