Frequently Asked Questions
Where does the middleware run?
I deploy on your preferred hosting — AWS, Google Cloud, DigitalOcean, Railway, or Render. I also provide Docker containers for on-premise deployment.
Is it scalable?
Yes — I build with event queues (Bull/Redis) and horizontal scaling in mind. The architecture handles thousands of webhooks per minute.
Do you provide monitoring?
Yes — I set up logging, error alerting (Slack/email), and health check endpoints so you always know your integrations are running.
