Modules

Everything an account needs. Nothing it doesn't.

Eight production-ready modules. Deploy any combination via API, SDK, or hosted UI.

Profile Management

Full customer profile CRUD, custom field schemas, avatar hosting, and real-time sync across your stack.

Session & Security

JWT sessions, MFA, SSO/SAML, device fingerprinting, and built-in anomaly detection. Secure by default.

Order History

Full transaction ledger, real-time status tracking, refund workflows, and exportable order data.

Invoicing

Auto-generated PDF invoices, custom templates, billing portal, and tax line item support out of the box.

Address Book

Smart address management with global validation, autocomplete, and cross-account deduplication.

Preferences & Wishlists

Cross-device user preferences, saved items, and personalization settings with real-time sync.

Integration

From zero to production in a day.

Three steps. One SDK. Choose your deployment model and ship.

1
Install

Add the Maccsy SDK to your project via npm, or skip the install entirely and talk directly to the REST API from any language.

2
Configure

Initialize with your Project ID and secret key. Define which modules you need — only pay for what you enable.

3
Deploy

Go headless via API, drop in pre-built React components, or hand off the entire account portal as a white-label hosted UI.

terminal
# Install the Maccsy SDK
npm install @maccsy/sdk

# REST API — no install needed
curl https://api.maccsy.io/v1/accounts \
  -H "Authorization: Bearer mcs_live_..."
import { createClient } from '@maccsy/sdk'

export const maccsy = createClient({
  projectId: 'proj_xxxxxxxx',
  secretKey: process.env.MACCSY_SECRET_KEY,
})
// White-label portal — one component
import { AccountPortal } from '@maccsy/react'

export default function AccountPage() {
  return <AccountPortal userId={userId} />
}
// Or keep it headless — your UI, our data
