I’m building a SaaS app and need to send webhooks when users update data — what should I use?

For a SaaS app, you usually want a reliable outbound webhook system rather than “just firing an HTTP request” inline.

What to use

Best option: a webhook delivery service/queue + worker

Use:

• An event queue for webhook jobs
• A background worker to send them asynchronously
• Retries with exponential backoff
• Delivery logs + dead-letter handling
• Signing secrets so customers can verify requests

This avoids slowing down your user’s update request and makes delivery much more reliable.

Common architecture

1. User updates data in your app
2. You save the change in your database
3. You create a webhook event record/job
4. A worker sends the webhook to the customer endpoint
5. If it fails, retry automatically
6. Record status and response for debugging

Good tools, depending on your stack

If you want to build it yourself

• Node.js: BullMQ / RabbitMQ / SQS
• Python: Celery / RQ / SQS
• Ruby: Sidekiq
• Go: Asynq / native queues
• .NET: Hangfire / Azure Queue Storage

If you want managed infrastructure

• AWS SQS + Lambda/ECS worker
• Google Cloud Tasks
• Azure Queue Storage / Service Bus
• Redis-based queues if simpler and lower volume

If you want a ready-made webhook platform

Consider products like:

• Svix
• Hookdeck
• Trigger.dev (more workflow-oriented)

These are useful if you want retries, observability, and customer-facing webhook management without building everything yourself.

Key things you should support

• At-least-once delivery semantics
• Idempotency on the receiving side
• HMAC request signing with per-customer secrets
• Retries for transient failures
• Timeouts and endpoint health tracking
• Versioned event payloads
• Event replay from logs

My recommendation

If you’re early-stage:

• Use SQS/Cloud Tasks + a worker
• Add event storage + retries
• Sign requests with HMAC
• Provide a simple webhook dashboard later

If you want to move fast and avoid infrastructure work:

• Use Svix or Hookdeck

If you tell me your stack (e.g. Node, Python, AWS, etc.) and scale, I can recommend a specific setup.
