Pain Points → API Solutions
The problems Festive faces daily, and exactly how MYOB API automation solves each one.
😤
Manual Invoice Entry
Every sales quote accepted → someone manually creates an invoice in MYOB. 37% of AP professionals say this is their #1 pain.
API Solution
Festive Quote Generator → webhook → n8n → POST /Sale/Invoice to MYOB API. Invoice created in 2 seconds, zero re-keying.
📦
Inventory Desync
Parts and cabinets sold on website but MYOB inventory not updated. Stock outs, overselling, embarrassing calls to customers.
API Solution
Inventory webhook fires on every sale → n8n adjusts MYOB inventory levels via PUT /Inventory. Real-time sync, zero stock surprises.
💸
Overdue Payment Chasing
Someone has to run reports in MYOB, find overdue invoices, manually email each customer. Hours per week, easy to miss one.
API Solution
n8n scheduled job → GET /Sale/Invoice with filter status=Overdue → auto-email via Brevo. 30/7/1 day escalation reminders. Zero manual chasing.
📋
Compliance Deadline Panic
HFC phase-down, MEPS deadlines, equipment age tracking — all in spreadsheets. One missed deadline could mean fines.
API Solution
Compliance Compass → webhook → n8n → creates MYOB Purchase Order for replacement equipment + calendar reminders. Never miss a deadline.
🔧
Parts Ordering Chaos
Spare parts orders via email only. No tracking, no auto-invoice, no purchase order in MYOB. Just hope someone follows up.
API Solution
Parts Order submitted → n8n → POST /Purchase/Order to MYOB (creates PO) + email confirmation to customer + internal Slack alert. Full audit trail.
📊
No Real-Time Dashboard
Owner has to wait for month-end reports. Can't see today's cash position, job profitability, or outstanding debts at a glance.
API Solution
n8n scheduled job → GET reports from MYOB API → push to dashboard (Festive Hub Innovation Lab) → always-current P&L, cashflow, job costing.

OAuth 2.0 Setup (Step-by-Step)
Once, then done forever. MYOB uses OAuth 2.0 for API authentication. Here's exactly how to set it up.
1
Register as MYOB Developer
Go to myob.com/developer, create an account, register your app. You'll get a Client ID and Client Secret.
2
Configure OAuth Scopes (March 2025 Update)
MYOB now requires granular scopes — no more CompanyFile blanket access. Select exactly what you need:
Required scopes for Festive:
sme-sales · sme-inventory · sme-purchasing · sme-banking
3
Set Redirect URI
Point this at your n8n instance (self-hosted on Festive VPS):
https://festive.helloweb.space/n8n/oauth/callback
4
First Authorisation
Visit the auth URL in your browser. MYOB asks a company file admin to approve access. Click Allow. OAuth tokens are returned.
5
Token Refresh (Automatic)
Access tokens expire in ~20 minutes. n8n automatically uses the refresh token to get a new one. No manual re-auth needed — set and forget.
6
Get Company File GUID
After auth, MYOB returns the Company File GUID in the redirect URI. This GUID goes in every API request endpoint.
https://api.myob.com/accountright/{CompanyFileGUID}/Sale/Invoice
Key MYOB API Endpoints
The endpoints Festive will actually use. All require the Company File GUID in the URL path.

🏆 Recommendation For Festive
1. Use n8n self-hosted on your VPS — already running Docker, $0/month, full OAuth control for MYOB, JavaScript when visual hits limits. Your data stays in NZ.
2. MYOB API via HTTP Request node — no native MYOB node exists in ANY platform. n8n's HTTP Request node with OAuth 2.0 credentials is the cleanest path. Configure once, reuse forever.
3. Start with 3 workflows:
- Parts Order → MYOB Purchase Order + Email Confirmation
- Quote Accepted → MYOB Invoice Creation
- Daily Overdue Invoice Chaser (automated emails)
4. Add Brevo (free) for email delivery — 9,000 emails/month free, professional deliverability, NZ-compatible.
5. Total cost: $0/month (n8n on existing VPS) + time (2-3 hours initial setup, then 2hrs/month maintenance).
Saves: ~47 hours/month of manual work → $3,500+/month in staff time (at $75/hr NZ avg).
