Kustomer + Stamped

Kustomer is a Customer Relationship Management (CRM) platform that helps you manage high support volume effortlessly.  

Stamped's Kustomer integration lets your agents track and see reviews directly in a customer's timeline. When a customer publishes a review in Stamped, the integration creates or updates a custom Review object with up to 20 custom fields on that customer's timeline.

Example of a custom Review added to a customer's timeline after publishing a review:

Key Notes

• Plan: the Kustomer integration is available on our higher-tier Reviews plans. Check Account > Your Plan, or contact support@stamped.io if you are unsure whether yours includes it.
• Stamped sends every new review to Kustomer. Stamped has no rating filter, so if you only want to act on negative reviews, you'll filter them in Kustomer.

• Step 1: Installing Stamped in Kustomer
• Step 2: Add the webhook in Stamped
• Filtering which reviews create work in Kustomer

Step 1: Install Stamped in Kustomer

To integrate Stamped with Kustomer, install the Stamped app from the Kustomer App Directory.

1. Go to Settings and select Apps > App Directory.
2. Locate Stamped from the list, then select Install.
3. Go to Settings and select Platform > Inbound Webhooks > Form Hooks.
4. Locate the Sync Stamped user reviews hook, select the Menu icon at the right side of the row, then select Copy Hook Address. Paste this into Stamped in the next step.

Step 2: Add the webhook in Stamped

Now log in to Stamped to point the webhook at Kustomer.

1. Log in as an administrator in Stamped and go to Settings > Webhooks.
2. Select Add Webhook.
3. Fill out the fields as follows:
   • Payload URL: paste the Hook Address you copied from Kustomer.
   • Secret: leave blank.
   • Is Active: check this box. Uncheck it whenever you want to pause the integration.
   • All events: leave this unchecked, then under Choose Events, check New Reviews only.
4. Save the webhook.

Do not check "All events". That subscribes Kustomer to every Stamped webhook topic, including Questions & Answers, NPS, checkout comments, and all rewards events, as well as review changes beyond new submissions. Merchants who leave it checked see Kustomer fill with items they never intended to act on. Select New Reviews and nothing else.

Filtering which reviews create work in Kustomer

This is the most common follow-up question, so it is worth being explicit about where the boundary sits.

Stamped does not filter by star rating. Stamped sends every new review to Kustomer, whether it is 5 stars or 1 star. Stamped only controls which event types are sent, not which reviews within an event type.

To act only on low-rated reviews, filter in Kustomer. The review payload Stamped sends includes a reviewRating field containing the star rating as a number from 1 to 5, along with fields such as reviewTitle, reviewMessage, productName, and customerEmail.

In your Kustomer Workflow, add a condition on reviewRating before the step that creates a conversation or ticket. For example, continue only when reviewRating is less than or equal to 2, so a 1- or 2-star review raises a ticket while higher ratings still land on the customer's timeline without creating work for your agents.
