The Webhook.site Command Line Interface allows you to interact with your Webhook.site URLs using a terminal on your computer or a server, or programmatically in scripts.
The CLI is still in its infancy, and currently it's main functionality is to redirect traffic from your Webhook.site URL to the machine where the CLI is being run. You then specify a URL for where the requests should be sent, allowing you to redirect traffic to machines that are not able receive connections directly from the Internet.
For development information, please see the Github Page.
If you have installed Docker, you can simply run Webhook.site CLI via
docker run, like this:
docker run webhooksite/cli -- index.js help
Node version 14 or greater required.
npm install -g @webhooksite/cli
help: List commands¶
Lists commands available to the CLI.
forward: Forward requests¶
forward command listens for new incoming requests sent to your Webhook.site URL and immediately relays them to any URL you specify, or simply
localhost (so it can be used as an ngrok alternative). This URL can be any URL that the machine running Webhook.site CLI can access.
The request method, headers and any additional path or query string parameters added to the Webhook.site URL is forwarded on to the target. For example, if the target URL is
https://example.com, sending a POST request to
https://webhook.site/c33f3c3e-6018-4634-b406-65338edee460/example?query=value, the target URL will also receive a POST request on
- The token ID (
--token) parameter must specify the token ID. The token ID is the long 36-character ID at the end of your Webhook.site URL.
- An API key (
--api-key) must also be specified, and can be generated from the Webhook.site Control Panel.
- Finally, the target (
--target) specifies where traffic should be redirected.
Accessing localhost/127.0.0.1 when using Docker¶
Note that per default, the host machine running the Docker command won't be available as
127.0.0.1 inside the Docker container, as the container has its own network space. This will cause errors like
FetchError: request to http://127.0.0.1:8080/ failed, reason: connect ECONNREFUSED 127.0.0.1:8080.
If you wish to forward requests to the host machine, you either use host-mode networking (with the
--network=host option to the
docker run command), or use your host machine's LAN IP (usually in the ranges 10.x.x.x, 192.168.x.x or 172.16.x.x.) For more information, please see this Stackoverflow thread.
