Quickstart

Get from zero to recovering churned customers in 5 minutes.

1. Create an Account

Sign up at the Windback dashboard with your email, name, and password.

After signing up you'll be logged in automatically and taken to the dashboard.

2. Get Your API Keys

Go to Settings in the dashboard to find your API keys:

• Public Key (pub_...) — Used for the cancellation widget and webhook URLs
• Secret Key (sk_...) — Used for SDK integrations and server-side API calls

3. Connect Your Payment Provider

Add a webhook URL in your payment provider's dashboard:

https://api.windback.dev/api/v1/webhooks/{provider}/{your_public_key}

Replace {provider} with stripe, razorpay, or custom.

For Stripe, listen for the customer.subscription.deleted event.

4. (Optional) Add the Cancellation Widget

Add this snippet to your app's cancellation flow:

<script
  src="https://api.windback.dev/widget.js"
  data-api-key="pub_your_key_here"
  async
></script>

This captures cancellation reasons before the customer leaves.

5. View Events in the Dashboard

Once webhooks start flowing, you'll see churn events in your dashboard.

6. Generate & Send Recovery Emails

Click on any churn event, then click "Generate AI Recovery Emails". The AI creates 9 personalized variants. Preview them, pick the best one, and send it with one click.
