# Fairing Analytics: Post-Purchase Survey Data

> Fairing post-purchase survey responses — attribution answers, NPS scores, and custom questions — synced to Hazel for true channel insights.

## Overview

[Fairing](https://fairing.co/) captures post-purchase survey responses — the "How did you hear about us?" question and more. Connect it to Hazel to compare what customers say with what your ad platforms report, and get a clearer picture of what's actually driving sales.

## What Hazel pulls

Once you connect Fairing, Hazel has access to:

* **Survey responses** — answers to every survey question you've asked
* **Attribution answers** — responses to "How did you hear about us?" and similar discovery questions
* **NPS scores** — Net Promoter Score data (a measure of how likely customers are to recommend you, on a scale of 0-10)
* **Custom question responses** — answers to any custom questions you've added to your surveys

## How to connect

Find Fairing in the [Hazel marketplace](https://app.fromhazel.ai/integrations/marketplace?search=fairing) and click the **+** button. You'll need to paste your Fairing API key.

**What you'll need:** Your Fairing API key, found in your Fairing account settings.

## Example questions you can ask

Once your Fairing data is connected, try questions like these:

* "What are customers saying about how they found us?"
* "Show me our NPS score trend"
* "Compare Fairing attribution data to ad platform reported data"
* "What percentage of customers say they found us through a friend?"
* "How has our NPS changed over the last 6 months?"
* "Which acquisition channels do first-time buyers report most often?"

## Good to know

<Tip>
  **Attribution comparison** is one of the most powerful uses of Fairing data. Compare what customers tell you (survey responses) with what ad platforms claim (click-based attribution) to understand where your money is really working.
</Tip>

* **NPS** stands for Net Promoter Score. It measures how likely customers are to recommend you, on a scale of 0-10. Scores of 9-10 are "promoters," 7-8 are "passives," and 0-6 are "detractors."
* Pair with Shopify and your ad platforms for the most complete attribution picture.
* Your data refreshes roughly every 6 hours.
