Make your product programmable.
An API lets developers change things in your product. Webhooks tell them when something changed, which is what they need to build real integrations on top of you.
Why developer tools send webhooks through Svix
Developers judge your webhooks the same way they judge your API: clear payloads, signature verification, SDKs in their language, and a way to test and debug. Building all of that in-house is months of work that isn't your product.
SDKs in every language
Svix ships SDKs in the languages your users write, and verifying a webhook signature takes a few lines in any of them.
A portal that looks like yours
Drop in the prebuilt webhook portal with one line of code, or build your own UI on the React library to match the rest of your product.
A documented event catalog
Publish your event types with schemas and examples, so developers know what each payload looks like before they write any code.
“At my previous company (WorkOS) we had to build a lot of infrastructure internally to support webhooks. It was very complex, hard to maintain, so when I started Resend I already knew we didn't want to build webhooks ourselves.”

Features
Logs and Monitoring
Monitor deliverability, debug failures, and notify customers automatically.
Security
Signed payloads and secret rotation stop SSRF, replay, and forged events.
Automatic & Manual Retries
Failed messages recover automatically. Retry instantly via API or the portal.
Multi-tenancy
Isolate endpoints, logs, and config per customer from one deployment.
Event Filtering
Let each endpoint subscribe to only the events it cares about.
Multi-region
Deliver from the region closest to your customers for data residency.
Payload Transformations
Reshape or enrich payloads inflight before they reach each endpoint.
Throttling
Rate-limit delivery per endpoint to protect slow or overloaded consumers.
Developer Experience
Simulate, test, and replay any event. Inspect and debug webhooks end to end.

"card_id": "card456",
"event": "card.activated",
"user_id": "user789"
}
Advanced Endpoints
Go beyond standard webhooks. Use polling and FIFO-ordered delivery, or stream events straight into S3, Azure, and GCS buckets.
Security and compliance
Svix is SOC 2 Type II audited and compliant with HIPAA, PCI DSS, PIPEDA, GDPR, and CCPA. Event data can stay in the US, EU, Canada, Australia, or India, or in a private region dedicated to you. The enterprise tier adds custom compliance requirements and hands-on support.
Svix had a level of product maturity and a brand that we were very comfortable with putting in front of our customers. Brex customers have a certain expectation of us, and we need partners that can deliver at that level.
Managing our own webhook system was a nightmare... Ever since we added Svix we are all at ease. No more retries, no more endpoint failures, no random webhook errors. We had our best engineers working on it, and they are now free to focus on innovating on our product.
Svix's platform is reliable, fast, and makes our lives easier by handling the complexities of webhooks, allowing us to deliver a better experience for our users.
Adding Svix to the mix was definitely the right decision for us. In addition to happy customers, our engineers have their evenings back.
Svix's well-designed API and libraries enabled us to offer webhooks in a fraction of the time it would have taken us otherwise. Additionally, the responsiveness and feedback-friendly nature of the Svix team added immense value.
Integration gaps had cost us deals. Svix is how we get ahead of that – instead of chasing every integration request, we give developers the foundation to build what they need.
At my previous company (WorkOS) we had to build a lot of infrastructure internally to support webhooks. It was very complex, hard to maintain, so when I started Resend I already knew we didn't want to build webhooks ourselves.
We are extremely happy with Svix! It has helped us launch webhooks for our customers extremely quickly, the infrastructure is reliable, and it has saved us countless engineering hours.
I very much appreciate how much time Svix saved us. We were able to get a webhooks MVP out in less than a day.
