Redis Queue Buffers Protect Apps from Webhook Overload During Traffic Spikes

High-volume webhook traffic from platforms like Stripe, Shopify, or Twilio can overwhelm servers when payloads are processed synchronously inside HTTP controllers, causing timeouts and data loss. The recommended solution is an asynchronous Redis queue buffer that fully decouples the public-facing HTTP layer from internal business logic and database operations. Under this pattern, the controller only validates the incoming request signature, pushes the raw payload into an in-memory Redis queue, and immediately returns a 202 Accepted response within milliseconds. A separate pool of background workers then processes the queued payloads at a controlled pace, shielding the relational database from sudden connection spikes. This architecture ensures webhook providers receive timely acknowledgements while the application handles complex data processing safely in the background.
