Real-Time Sync · API2Cart
Real-Time eCommerce Data Synchronization
Keep your application in perfect sync with eCommerce stores. Bidirectional, real-time data flow for orders, products, inventory, and customers across 70+ platforms.
Real-time data synchronization is the backbone of modern eCommerce software. Your app needs to reflect changes the moment they happen in a merchant’s store.
API2Cart combines webhooks (push) and optimized polling (pull) into one sync layer. Changes trigger instant notifications, and your app can write updates back — all through one API.
How Real-Time Sync Works in API2Cart
- Webhooks (push): subscribe via webhook.create for instant change notifications
- Polling (pull): list endpoints with modified_from for efficient delta sync
- Bidirectional: read (order.list, product.list) and write (product.update)
- Conflict resolution: every entity returns a modified_at timestamp
Example request
?modified_from=2026-01-01+00:00:00
&count=100
&response_fields={result{order{id,status,modified_at}}}
