E-commerce platformsEUAn order from your OpenCart store appears in the CRM within minutes, the manager calls the customer with the full cart in front of them, and the delivery status goes back to the store on its own.
OpenCart is a popular open-source store platform: a catalogue, orders, customers, several stores under one admin panel, extensions for payments and delivery. Sales, however, usually happen outside the store — in a CRM, on the phone, in messengers — and orders are copied there by hand. CoreviaFlow connects OpenCart to your CRM so that a new order lands with the manager on its own, the customer's card is shared, and statuses return to the store without retyping.
Before the manager refreshes the store admin panel all day and copies orders into the CRM, and the evening orders are noticed the next morning.
After an order placed in the store appears in the CRM within minutes with the customer, the items, the address and the payment method; the manager calls right away.
Before the parcel has been sent, but the store still says 'processing', and the customer writes to ask.
After when the CRM marks the order shipped or delivered, the status changes in the store as well, and the customer sees it in their account.
Before the person who calls is a stranger to the manager, although they have ordered from the store four times.
After the store customer is matched to the CRM card by phone and email, and the manager sees the whole history — orders, returns, complaints — before picking up the phone.
Before the store keeps selling an item that ran out, and the manager has to call and apologise.
After balances and prices come from your accounting system to the store on a schedule, and a sold-out item leaves the storefront before anyone orders it.

In the admin panel (System → Users → APIs) OpenCart creates credentials for outside applications — inventory systems, ERP, mobile apps and other services.

Source: www.opencart.com ↗ checked 2026-09-28Access to the store is granted through an API key created in the admin panel, and OpenCart itself recommends restricting each key to specific IP addresses — the server that connects must therefore have a static address. The generated key is shown only once; after saving it cannot be viewed again and has to be reissued if lost. The event system of OpenCart 4.x runs as code inside the store: handlers are functions in the store's own files, so there is no ready-made outgoing notification to outside systems — a small extension has to be added, or the CRM checks the store on a schedule. Extensions are written for OpenCart 4.x (its MVC-L pattern, events and OCMOD), which means development in PHP; a store on version 3.x is a separate case with its own upgrade path.
