Svix CLI

GitHub release (latest by date) GolangCI Go Report Card

A CLI to interact with the Svix API.

With the Svix CLI, you can:

  • Interact with the Svix CLI
  • Validate Webhook payloads



The Svix CLI is available on macOS via Homebrew:

brew install svix/svix/svix


The Svix CLI is available on Windows via the Scoop package manager:

scoop bucket add svix
scoop install svix


The Svix CLI is available on Linux via:

Pre-built executables

You can download and use our pre-built executables directly from our releases page, and use them as is without having to install anything.

  1. Download and extract the tar.gz archive for your operating system.
  2. Run the svix executable from the command line: ./svix help.

Note: you may need to allow execution by running chmod +x svix.

You can also put the binaries anywhere in your PATH so you can run the command from anywhere without needing to provide its full path. On macOS or Linux you can achieve this by moving the executable to /usr/local/bin or /usr/bin.


Installing the Svix CLI provides access to the svix command.

svix [command]

# Run `svix help` for information about the available commands
svix help

# or add the `--help` flag to any command for a more detailed description and list of flags
svix [command] --help

Using the listen command

The listen command creates an on-the-fly publicly accessible URL for use when testing webhooks.

NOTE: You don't need a Svix account when using the listen command.

The cli then acts as a proxy, forwarding any requests to the given local URL. This is useful for testing your webhook server locally without having to open a port or change any NAT configuration on your network.


svix listen http://localhost:8000/webhook/


Webhook relay is now listening at

All requests on this endpoint will be forwarded to your local url:

View logs and debug information at
To disable logging run "svix listen --no-logging"

The above command will return you a unique URL and forward any POST requests it receives to http://localhost:8000/webhook/.

Interacting with the Svix server

# Set your Auth Token temporarily via the SVIX_AUTH_TOKEN environment variable
# or to persistently store your auth token in a config file run
svix login # interactively configure your Svix API credentials

# Create an Application with the name "Demo"
svix application create '{ "name": "demo" }'
# or pipe in some json
echo '{ "name": "demo" }' | svix application create
# or use the convenience cli flags
svix application create --data-name demo

# List Applications
svix application list --limit 2 --iterator some_iterator
