Salesforce Classic Browser Automation

Automate Salesforce Classic — the reliable way to interact with Salesforce Classic programmatically, with or without an official API.

What This Is

Salesforce Classic (CRM) is notoriously difficult to automate via its official API — limited endpoints, complex authentication (Okta / Azure AD / SAML), and browser-only workflows make traditional API integration a pain.

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

This system requires MFA (Salesforce MFA / Authenticator). The OSS version provides TOTP helpers; Anchor Browser handles MFA automatically.

Quick Start

git clone https://github.com/Browser-Automation-Hub/salesforce-classic-browser-automation.git
cd salesforce-classic-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_salesforce() — Authenticate to Salesforce Classic with SSO/MFA
• create_lead() — Create leads and contacts programmatically
• update_opportunity() — Bulk update opportunity stage and fields
• run_report() — Run and export Salesforce reports to CSV
• mass_update_records() — Mass update records that DLRS/Data Loader cannot handle

Use Cases

• CRM teams on Salesforce Classic unable to upgrade
• Lead import automation
• Report scheduling without Connected App
• Legacy org data migration

Option A: Open Source (Puppeteer)

Prerequisites

• Node.js 18+
• Google Chrome / Chromium installed
• Salesforce Classic account with appropriate permissions

Installation

npm install
cp .env.example .env

Configuration (.env)

SALESFORCE_CLASSIC_URL=https://login.salesforce.com
SALESFORCE_CLASSIC_USERNAME=your-username
SALESFORCE_CLASSIC_PASSWORD=your-password
MFA_SECRET=your-totp-secret-if-applicable
SESSION_PATH=./session.json

Basic Login Example

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

async function main() {
  const page = await createSession();
  const result = await login_salesforce(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_salesforce } = require('./src/actions');

async function main() {
  await withAnchorBrowser(async (page) => {
    // MFA, SSO, CAPTCHAs all handled automatically
    const result = await login_salesforce(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 (Okta / Azure AD / SAML) — intercepts the SAML redirect and completes the IdP flow
3. MFA / TOTP (Salesforce MFA / Authenticator) — generates TOTP codes via otpauth library
4. Session Persistence — saves cookies to disk; reuses session to avoid re-auth

Handling Salesforce MFA / Authenticator 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?

Salesforce Classic Classic has deprecated API support, and many orgs cannot upgrade to Lightning. Browser automation is the most reliable workaround.

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 Salesforce MFA / Authenticator MFA automatically
• Enterprise compliance: SOC2, HIPAA, ISO27001

Known Selectors Reference

These CSS selectors were observed in Salesforce Classic web interfaces. Enterprise applications update their UIs — verify against your specific instance and submit PRs when selectors break.

| Element | Selector | Notes | |---------|----------|-------| | Login: username | #username | Login form | | Login: password | #password | Login form | | Login: submit | #Login | Login form | | Login: mfa code | #smc | Login form | | create lead: new lead url | /00Q/e | | | create lead: first name | #name_firstlea2 | | | create lead: last name | #name_lastlea2 | | | create lead: email | #email | | | create lead: company | #company | | | create lead: save btn | #bottomButtonRow input[name="save"] | | | update opportunity: search opp | #phSearchInput input | | | update opportunity: opp row | .dataRow .actionColumn a | | | update opportunity: stage dropdown | #opp12 | | | update opportunity: close date | #closedate | | | update opportunity: save btn | input[name="save"][value="Save"] | | | run report: reports tab | a[title="Reports Tab"] | | | run report: report row | .ReportName a | | | run report: export xls | #export_btn | | | mass update records: list view | .listViewport | | | mass update records: select all | #cbAll | | | mass update records: mass update btn | input[value*="Update"] | |

⚠️ Selectors are best-effort. Run node src/utils.js --verify-selectors to test against your instance.
