Svix - Webhooks as a service
Website | Documentation | Community Slack
Example Svix Application
This is an example Next.js application showing how to use Svix both as a provider (sender) and a consumer (receiver) of webhooks.
While this application is writing in TypeScript and targets Next.js, it's a useful example for all other languages and frameworks, and shows how to structure an integration.
The application consists of a fake Signup form to let a customer "signup" to your application, a fake Dashboard that is meant to simulate your real application, and a Webhooks Portal to let your customers interact with the webhooks dashboard (add endpoints, see logs, etc).
What is Svix?
Svix makes it easy for developers to send webhooks. Developers make one API call, and Svix takes care of deliverability, retries, security, and more. For more information, please refer to the Svix homepage.
You can find general usage documentation at https://docs.svix.com. For complete API documentation with code examples for each endpoint in all of our official client libraries head over to our API documentation site at https://api.svix.com.

This codebase contains example code for a webhooks provider (Svix customer), a webhook consumer (Svix customer's customer), and some boilerplate Next.js code. It includes both the UI parts and the server API parts.
These files demonstrate how a Svix integration looks like from on provider's (Svix customer) side. This covers both the API and the UI parts.
This file implements a fake signup flow and demonstrates how to create a Svix Application for the customer (consumer) once they sign up to your application.
This file is meant to represent business logic on your end, and demonstrates how to send webhooks once events occur on the backend.
This file demonstrates how to securely give your customers access to the pre-built Application Portal. This works in tandem with the UI part below, and supplies it with the login magic link.
This page shows how to embed the Svix application portal in your UI using the Svix React library. This page requires the above app portal API page.
These two files aren't actually important. They are only needed for a functional example, and are there to simulate having a real application.
This API endpoint demonstrates how a consumer of webhooks should verify the integrity of the webhooks using the Svix libraries:
Running it locally
Clone the repository and install needed dependencies
git clone https://github.com/svix/svix-example cd svix-example # Install needed deps npm i
Create a file called
.env.local and set both the Svix token (get yours from dashboard.svix.com), and a placeholder webhook secret (we'll get the real one later):
# Provider config SVIX_TOKEN=testsk_SInWH9Tx7tS4Him4re6Zawyx0vf7XlU.eu # Consumer config SVIX_WEBHOOK_SECRET="whsec_dont_worry_about_it_for_now"
Creating the needed event types
This example assumes your environment has two event types:
invoice.deleted in your environment. To create them, please head to the event type page on the Svix dashboard. For more information about event types, please refer to the event types docs.
Verifying webhook signatures
The endpoints in the example will fail to verify the signatures because the webhook secret we set in the previous section is bad. In order to fix that, you would need to navigate to the Webhooks Portal tab, click on the endpoint you created, copy the webhook secret, paste it in
.env.local, and restart your local server.
