Do I need to buffer webhook events in a queue?

Usually yes, if the webhook triggers anything non-trivial. A queue is a good idea when you need reliability, retries, or you expect bursts.

Use a queue if:

• You need to acknowledge the webhook quickly and process it later
• Processing can take more than a few seconds
• The webhook provider may retry on slow/failing responses
• You want decoupling between ingestion and downstream work
• You need retries, dead-lettering, or rate limiting
• Traffic can spike and you don’t want to overload your app or database

You may not need a queue if:

• The webhook just does a small, fast, idempotent action
• You can safely process it synchronously in a few hundred ms
• Losing or delaying occasional events is acceptable
• Your system is simple and low volume

A common pattern

1. Receive webhook
2. Verify signature
3. Store the event or enqueue it
4. Return 200 OK fast
5. Process asynchronously

Important note

If you use a queue, still make the handler idempotent. Webhooks are often delivered at least once, so duplicates happen.

Rule of thumb

• Production + important side effects: use a queue
• Tiny internal webhook or prototype: maybe not

If you want, I can help you decide for your specific webhook by looking at:

• event volume
• processing time
• retry behavior
• whether duplicate delivery is acceptable
