A Magento order sits in Admin with a paid status and a shipped date. The review ask never leaves the warehouse. The product page still shows three old text reviews. The missing piece is not another Marketplace listing. It is a path from that order event to one invitation.

We make Idukki. This guide is the wiring pattern for Magento and Adobe Commerce. It is not another list of UGC apps. For Marketplace options, see best UGC apps for Magento.

Order event in, invitation out, review back on the product page.

Why webhooks beat a nightly CSV

A CSV export of yesterday’s orders arrives late. A buyer already forgot the unboxing. Adobe Commerce Webhooks and Magento observers fire when the order changes. That is the right moment to schedule an ask.

You still need a delay. Ask on “created” and the parcel is still in transit. Ask on “complete” or “shipped”, then wait a few days. The invitation API holds that delay.

The five-step pattern

From Magento order to live review

  1. 01

    Order event

    Webhook or observer fires on complete or shipped.

  2. 02

    Normalise

    Map Magento product and customer ids to the invitation payload.

  3. 03

    Invite

    Call the invitation API with delay, locale and product lines.

  4. 04

    Collect

    Buyer rates, writes, and can add photos or a video.

  5. 05

    Show

    Approved reviews feed the PDP widget and any UGC gallery.

The same shape on Adobe Commerce cloud or Magento Open Source. Your ESP or reviews tool owns the send.

What the invitation API needs

FieldWhy it matters
Order idDedupes invites and ties the review to a purchase
Buyer emailWhere the invite goes
Product ids / SKUsStars land on the right PDP
Locale / store viewLanguage and currency of the ask
Shipped or complete timeStarts the delay timer
Minimum fields for a Magento-triggered invite. Keep PII to what the ask needs.

Do not send billing address into the invitation call. Email, order id and line items are enough for a product review ask.

Three Magento shapes that work

  • Adobe Commerce Webhooks. Point a subscribed event at your invitation endpoint or a thin middleware.
  • Custom observer. On status change, enqueue a job that calls the invitation API.
  • Module order feed. A store module posts orders to your reviews or UGC platform, which schedules the ask.

Idukki’s Magento 2 module posts each order with the gallery visitor id. It is early access and not on the Marketplace. Catalogue sync and CMS galleries ride the same module. See the Magento setup.

Idukki’s automated review request email runs on Shopify order and fulfilment webhooks today. On Magento, treat the invitation send as your ESP or reviews tool until that path ships.

Moderation and display after the ask

Collection without moderation puts raw media on the PDP. Keep one queue for review text, photos and social posts. Approve once. Publish to stars and to a gallery near the buy button.

Photo reviews belong higher than the classic stars band. A UGC gallery can sit near the add-to-cart block while the stars widget keeps the text.

Checks before you go live

  1. 1Fire a test order through complete or shipped and confirm one invite.
  2. 2Retry the webhook and confirm the idempotency key blocks a second send.
  3. 3Submit a photo review and confirm it waits in moderation.
  4. 4Approve it and open the PDP on the matching store view.
  5. 5Confirm cancelled orders never schedule an invite.

Questions Magento teams ask

  • Should the invite fire on order create?

    Usually no. Wait for shipped or complete. Then add a delay of a few days so the product is in hand.

  • Can one webhook serve several store views?

    Yes, if the payload includes store view or locale. Route the invite language from that field.

  • Does Idukki send Magento review emails today?

    No. Automated review request email is Shopify-only. Magento orders can still reach Idukki through the early-access module.

  • Where do photo reviews show?

    In the review layouts and in the same library as social UGC, once approved. See /reviews.
