Do I need a webhook gateway for multiple SaaS integrations?

Not always.

You usually need a webhook gateway if you’re dealing with multiple SaaS integrations and you want a single place to receive, normalize, secure, route, retry, and monitor inbound webhooks. But for a small number of integrations, you can often just expose separate endpoints in your app.

You likely need a webhook gateway if you want:

• One public endpoint for many providers
• Unified auth/security handling
• Signature verification and secret management in one place
• Retry/dead-letter handling
• Event normalization across vendors
• Rate limiting / deduplication
• Observability for all webhook traffic
• Decoupling from your main application logic

You can probably skip it if:

• You only have 1–3 SaaS providers
• Each integration is relatively simple
• You can handle webhooks directly in your app
• You don’t need complex routing, replay, or transformation

A common middle ground

Build a lightweight internal webhook ingestion service that:

1. Receives all webhooks
2. Verifies signatures
3. Stores raw events
4. Pushes them to a queue
5. Lets downstream services process them

That gives you most of the gateway benefits without a heavy platform.

Rule of thumb

• Small/simple integrations → direct endpoints
• Many integrations / high reliability needs → webhook gateway or ingestion layer

If you want, I can help you decide based on your specific SaaS list, traffic volume, and architecture.
