Churnkey

Churnkey is a churn prevention platform that helps subscription businesses retain customers through personalized cancel flows, pause offers, and win-back campaigns. It tracks every customer interaction during the cancellation journey so you can understand why people leave — and what keeps them.

Connecting Churnkey to Coupler.io lets you move that retention data into the tools where you actually do analysis.

Why connect Churnkey to Coupler.io?

• Pull raw session data and aggregated metrics into Google Sheets, Excel, BigQuery, or Looker Studio without writing any code
• Send churn signals to AI tools like ChatGPT, Claude, or Gemini for automated retention analysis and recommendations
• Combine Churnkey data with CRM or billing sources using Join or Append transformations for a fuller picture of customer health
• Schedule automatic refreshes so your dashboards and reports always reflect the latest retention activity

Prerequisites

• A Churnkey account with at least one active cancel flow
• Your Churnkey API key (found in your Churnkey account settings under API/Developer options)

Quick start

Start with the Session aggregations entity if you want a high-level view of retention performance. Switch to Sessions when you need row-level detail on individual customer interactions.

1

Create a new data flow in Coupler.io. Log in to Coupler.io, click Add data flow, and select Churnkey as your source.

2

Enter your Churnkey API key. In the source settings, paste your API key into the designated field. You can find this key in Churnkey under your account or developer settings.

3

Select an entity. Choose either Sessions for individual interaction records or Session aggregations for summarized metrics. You can add more entities to the same data flow later.

4

Choose a destination. Pick where you want your data to land — Google Sheets, BigQuery, Excel, Looker Studio, or an AI destination like ChatGPT or Claude.

5

Run the data flow. Click Run to execute a manual sync. Once it completes successfully, your Churnkey data will appear in your chosen destination.
