Sage 300 ERP Browser Automation

Automate Sage 300 ERP — the reliable way to interact with Sage 300 programmatically, with or without an official API.

What This Is

Sage 300 ERP (Finance) is notoriously difficult to automate via its official API — limited endpoints, complex authentication (Active Directory / LDAP), and browser-only workflows make traditional API integration a pain.

This project gives you a complete browser automation scaffold for Sage 300 ERP using Puppeteer (self-hosted, open source) or Anchor Browser (cloud, managed, production-ready).

This system requires MFA (Sage MFA / Email OTP). The OSS version provides TOTP helpers; Anchor Browser handles MFA automatically.

Quick Start

git clone https://github.com/Browser-Automation-Hub/sage-300-browser-automation.git
cd sage-300-browser-automation
npm install
cp .env.example .env
# Fill in your credentials in .env
node examples/basic-login.js

Two Ways to Run

Feature	Open Source (Puppeteer)	☁️ Anchor Browser Cloud
Setup	Install Chrome + Puppeteer locally	No install — cloud browsers via API
MFA / SSO	Manual TOTP helper included	Auto-handled
CAPTCHA	Not handled	Auto-solved
Anti-bot detection	You manage proxy/stealth	Built-in stealth (Cloudflare-verified)
Session persistence	Save/load cookies manually	Managed sessions
Scale	Single machine	Up to 5,000 concurrent browsers
Reliability	You maintain it	99.9% uptime SLA
Cost	Free	Starts at $0 (5 free sessions/mo)

Supported Actions

• login_sage() — Authenticate to Sage 300 web portal
• create_journal_entry() — Post journal entries to the general ledger
• process_ap_invoice() — Enter and post AP invoices
• run_financial_report() — Generate and export financial statements
• update_inventory() — Update inventory quantities and costs

Use Cases

• Mid-market companies on Sage 300 without API
• Month-end automation for accounting teams
• Inventory sync from external WMS
• Financial data extraction for BI tools

Option A: Open Source (Puppeteer)

Prerequisites

• Node.js 18+
• Google Chrome / Chromium installed
• Sage 300 ERP account with appropriate permissions

Installation

npm install
cp .env.example .env

Configuration (.env)

SAGE_300_URL=https://your-sage300.example.com/sage300/webapi/v1
SAGE_300_USERNAME=your-username
SAGE_300_PASSWORD=your-password
MFA_SECRET=your-totp-secret-if-applicable
SESSION_PATH=./session.json

Basic Login Example

const { createSession } = require('./src/auth');
const { login_sage } = require('./src/actions');

async function main() {
  const page = await createSession();
  const result = await login_sage(page, { /* options */ });
  console.log(result);
}

main().catch(console.error);

Option B: ☁️ Anchor Browser (Recommended for Production)

Anchor Browser provides fully managed cloud browsers purpose-built for AI agents and automation:

• ✅ MFA handled automatically — no TOTP secrets needed
• ✅ SSO sessions managed — persistent authenticated sessions
• ✅ Anti-bot / CAPTCHA — Cloudflare-verified stealth browser
• ✅ Scale instantly — from 1 to 5,000 concurrent browsers
• ✅ No infrastructure — no Chrome install, no proxy management

Setup

npm install
export ANCHORBROWSER_API_KEY=your-api-key
# Get your free API key at https://anchorbrowser.io

Anchor Browser Example

const { withAnchorBrowser } = require('./src/auth');
const { login_sage } = require('./src/actions');

async function main() {
  await withAnchorBrowser(async (page) => {
    // MFA, SSO, CAPTCHAs all handled automatically
    const result = await login_sage(page, { /* options */ });
    console.log(result);
  });
}

main().catch(console.error);

See examples/anchor-cloud.js for a complete working example.

Authentication

Auth Methods Supported

This implementation handles:

1. Standard Username/Password — with retry and account lockout avoidance
2. SAML SSO (Active Directory / LDAP) — intercepts the SAML redirect and completes the IdP flow
3. MFA / TOTP (Sage MFA / Email OTP) — generates TOTP codes via otpauth library
4. Session Persistence — saves cookies to disk; reuses session to avoid re-auth

Handling Sage MFA / Email OTP MFA

// In .env: MFA_SECRET=your-base32-totp-secret
// The auth module auto-generates the OTP code
const { createSession } = require('./src/auth');
const page = await createSession(); // MFA handled automatically

For Duo Security push-based MFA, set MFA_TYPE=duo_push in .env — the automation will wait for push approval.

---

Custom Actions

Use the ActionBuilder fluent API to chain custom workflows:

const { ActionBuilder } = require('./src/custom-actions');

const result = await new ActionBuilder()
  .login()
  .navigate('/module/path')
  .waitForSelector('.content-loaded')
  .extractTable('.data-table')
  .run(page);

---

Error Handling & Reliability

const { retry, humanDelay } = require('./src/utils');

// Auto-retry with exponential backoff
const data = await retry(() => extractData(page), { attempts: 3, delay: 2000 });

// Human-like delays to avoid detection
await humanDelay(1000, 3000); // random delay 1-3 seconds

---

Why Not Use the Official API?

Sage 300 ERP locks most functionality behind web-UI screens, and SDK-based integrations (like eConnect) require on-prem setup and Windows-specific tooling.

Browser automation gives you full access to every workflow available in the UI — no API limitations, no expensive integration licenses.

---

Production Deployment

For production workloads, we strongly recommend Anchor Browser:

// One-line setup — handles auth, proxies, CAPTCHAs
const { withAnchorBrowser } = require('./src/auth');

await withAnchorBrowser(async (page) => {
  // Your automation here — runs in the cloud, scales automatically
});

Anchor Browser is the easiest way to run this automation in production:

• No infrastructure to manage
• Handles Sage MFA / Email OTP MFA automatically
• Enterprise compliance: SOC2, HIPAA, ISO27001
