Webhooks are harder than they seem...

Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect. Building a secure, reliable, and scalable webhook service is hard and time consuming. We built it so you can focus on what matters most, your business.

Unreliable user endpoints: Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability.

Monitoring and reliability: You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers.

Security implications: Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events.

Application Portal: You would need to build a UI for your users to add and remove endpoints, inspect logs and get ongoing reports.

Development experience: Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks.

A whole lot more: You need to implement versioning, event types, and develop, maintain and scale an always running webhook delivery system.

FAQs

What is webhooks as a service?

Webhooks as a service refers to Svix's software as a service (SaaS) webhook platform. We've built a user interface for managing your users' webhook subscriptions as well as an API that simplifies the process of implementing webhook best practices at scale.

Why webhooks as a service?

Let your valuable engineering resources work on solving problems unique to your product. Leverage Svix for your webhook infrastructure to ensure deliverability, reliability, security, and scalability.

What is a webhook service?

A webhook service is similar to "webhooks as a service" above, but also encompasses scenarios where the service is hosted by the service directly, rather than using the Svix WaaS offering. For example, a self-hosted instance of the Svix open source webhooks server would be considered a webhooks service.

Are your webhooks secure?

Yes! Our webhook service was designed for security from the ground up. We follow industry best practices, encrypt all data both in transit and at rest, and are SOC 2 Type II certified and GDPR compliant.

Can you handle our scale?

We process billions of webhooks a year for our customers, and we power webhooks for top companies like Brex and Lob. We can most likely handle your scale, but please reach out if you have any specific questions or requirements.
