Why Use Webhooks?

Total Flexibility

Connect GrowPanel to any system that can receive HTTP POST requests. Your server, Lambda function, or any cloud service.

Real-Time Delivery

Events are delivered immediately when MRR changes occur. No polling, no delays - instant data transfer.

Rich Payloads

Every webhook includes full customer details, MRR changes, plan information, and subscription metadata.

Event Filtering

Choose which events trigger webhooks. Filter by event type, minimum MRR, or currency.

Multiple Endpoints

Configure multiple webhook endpoints with different filters. Send churn to one system, new MRR to another.

Retry Logic

If your endpoint is temporarily unavailable, GrowPanel retries delivery with exponential backoff.

Simple Setup

Add your endpoint

Enter any HTTPS URL and configure your preferences. GrowPanel will send POST requests with JSON payloads whenever matching events occur.

Go to Settings > Integrations: Click the Webhooks card
Add your endpoint URL: Must be HTTPS
Set your threshold: Minimum MRR change to trigger
Choose event types: Select which events to receive
Test the connection: Send a test event to verify
