Unicommerce + WhatsApp: what actually works

API / Webhook Build — this page tells you plainly what is automatic today, what needs an export, and what isn't possible yet. No overclaiming.

Unicommerce is a multichannel order, inventory and warehouse management platform used by thousands of Indian D2C and marketplace sellers, with a documented REST API covering orders, shipments, inventory and returns.

What This Page Actually Promises

The honest scope

Unicommerce publishes real API documentation, so this is a genuine build, not a one-click app: WA.Expert doesn't have a pre-listed Unicommerce connector today. What works now is wiring Unicommerce's order/shipment events into WA.Expert's automation builder using the External API Request and Incoming Webhook steps, the same pattern used for Razorpay and other API-based integrations on this site.

What You Can Do

Ways businesses use Unicommerce + WhatsApp

📦

Order confirmed → WhatsApp confirmation

The moment an order is created in Unicommerce, send the customer a WhatsApp confirmation with order number and items.

🚚

Shipped → tracking link on WhatsApp

When Unicommerce marks an order as shipped, fire a WhatsApp with the AWB number and tracking link automatically.

↩️

RTO flagged → recovery message

A return-to-origin event triggers an automatic WhatsApp asking the customer to confirm the address or reschedule delivery, before the order actually returns.

📊

Low stock → manager alert

Inventory crossing a reorder threshold in Unicommerce sends a WhatsApp alert to whoever manages purchasing.

Setup Guide

How to set this up

Get API access from Unicommerce

Your Unicommerce account team or the documentation at documentation.unicommerce.com provides API credentials and endpoint access for your account.

Decide push or pull

Unicommerce supports webhook-style callbacks for some events; for others you poll the API on a schedule. WA.Expert's Incoming Webhook step accepts a push; the External API Request step can pull on a timer.

Map the order to a phone number and template

Pull the customer's phone number and order details from the Unicommerce payload, and map them to an approved WhatsApp template's variables.

Build the automation in WA.Expert

Use the visual automation builder: trigger (webhook or schedule) → data mapping → send WhatsApp template. No separate server needed for most setups.

Test with one real order

Run a live order through the flow end to end before switching it on for your full catalogue.

FAQ

Unicommerce + WhatsApp: common questions

Does WA.Expert have a ready-made Unicommerce app?

Not a one-click listed app today. What's real and available now is connecting Unicommerce's own documented API and webhooks to WA.Expert's automation builder, the same External API Request and Incoming Webhook pattern used for other API-based integrations on this site. It's a build, typically an afternoon's work, not an install.

Do I need a developer to set this up?

For the webhook and API mapping steps, yes, ideally someone comfortable reading API documentation. WA.Expert's own automation builder (the trigger, mapping and WhatsApp-send steps) is no-code once the connection is wired up.

What Unicommerce events can trigger a WhatsApp message?

Anything Unicommerce exposes through its API: order creation, status changes (packed, shipped, delivered), RTO/return events, and inventory levels are the most commonly used for WhatsApp automation.

Can this replace my existing order-status SMS or email?

Yes, most businesses that build this run it alongside or instead of SMS, since WhatsApp delivery and open rates are typically higher and the message can include a tracking link, image or button.

What if Unicommerce changes its API?

Like any API integration, a change on Unicommerce's side can require an update to your automation's data mapping. This isn't unique to WA.Expert, it's true of any custom API connection.

Is there a cost beyond my WA.Expert plan?

No separate WA.Expert fee for the automation itself. Each WhatsApp message sent is billed at Meta's rate with zero markup, the same as every other message on your account.
