API Access for Accounting Integrations

For Accountants and Developers

Build Stability provides two ways to pull invoice and GST data into external tools without requiring a formal Xero or MYOB partnership.

REST API (OAuth)

Use the developer API if your accounting software supports REST integrations: - GET /api/v1/invoices — list invoices with filters - GET /api/v1/invoices/:id — single invoice detail - GET /api/v1/invoices/gst-report — GST summary for date range

Find authentication details on the Developers page (accessible from Settings). You will need to create an API client with read scope.

MCP (for AI Agents)

If you use AI coding assistants or custom agents, Build Stability supports the Model Context Protocol: - buildstability/list_invoices — list invoices - buildstability/get_gst_report — GST summary

Suitable for: Sole, Rounded, and any accounting tool that supports custom data sources or REST APIs. All data is read-only. Your client data stays within Build Stability.
