Social proof can drive conversion rates in SaaS platforms, but implementing review systems requires backend infrastructure. This guide explains how to integrate Trustpilot's review platform with Webflow to build production-grade social proof features without maintaining your own review system.
Trustpilot provides review management through REST APIs, while Webflow generates semantic HTML with programmatic CMS capabilities. Together, they let SaaS platforms display real-time customer reviews, aggregate ratings, and dynamic social proof without review infrastructure.
This integration works well for SaaS platforms that need authenticated review collection, automated review display, and social proof across multiple product pages or customer segments.
The integration follows a webhook-driven, API-synchronized pattern where Trustpilot serves as the review system of record, and Webflow handles presentation and content management.
The following diagram illustrates the data flow from customer review submission through Trustpilot's API, backend processing, and final display in Webflow:

The architecture supports two implementation approaches:
Key components include authenticated API communication, real-time webhook processing, and CMS-driven content management that automatically updates social proof elements across your SaaS platform.
Before starting, you'll need active accounts and development environments for both platforms.
