Webhooks-as-a-service handling delivery, retries, security, and a customer-facing portal.
Svix provides outbound webhooks as a service. Instead of building webhook infrastructure themselves, API-first companies send events to Svix, which handles fan-out delivery to customer endpoints, automatic retries with backoff, signature-based security, rate limiting, and a white-labeled portal where customers manage their own endpoints and inspect delivery logs. In a revenue stack, webhooks are how billing, usage, and entitlement events reach customers and downstream systems reliably — the event architecture underneath integrations.

It productizes the long tail that makeshift webhook senders skip: retry semantics, endpoint failure handling, signing key rotation, and self-service debugging for the receiving customer. That last piece — the embeddable consumer portal — is the differentiator support teams feel, because webhook debugging tickets largely disappear.
Naive sending fails quietly: customer endpoints go down, retries without backoff hammer them, unsigned payloads get spoofed, and every delivery question becomes a support ticket. Webhook infrastructure is deceptively deep, which is exactly why it makes a clean build-vs-buy candidate.
Yes — billing events are among the highest-stakes webhooks a platform sends. Invoice created, payment failed, usage threshold crossed, and entitlement changed all trigger customer-side automation, so delivery guarantees and auditable logs matter more here than for most event types.
