CLI Basics
Overview
Relay CLI provides a variety of ways to configure request routing and also acts as an agent for request forwarding and tunnelling. Main features:
automatically configure bucket, input and output for webhook forwarding with
relay forwardcommandautomatically configure tunnel with
relay connectcommandmanage buckets, inputs and outputs for one-way request forwarding
manage tunnel subdomains, destinations and authentication details
manage access keys and secrets
Authenticate
In order to start using your CLI, you first have to authenticate. Create your key & secret pair here: https://my.webhookrelay.com/tokens. Then, there are two ways to do it:
Using
logincommand CLI will take advantage of native secure storage:
relay login -k token-key-here -s token-secret-hereEnvironment variable option is very useful when automating things:
export RELAY_KEY=token-key
export RELAY_SECRET=token-secretForward
Forward command automatically creates configuration and starts one-way request forwarding:
relay forward --help
Usage: relay forward [OPTIONS] [DESTINATION | COMMAND ARGS]
Create forwarding configuration (automatically creates bucket, input endpoint and output destination). If destination and bucket aren't specified - starts a relay for all endpoints
Options:
-b, --bucket string Bucket name (defaults to destination name if not supplied)
--command string Command to execute, must be used with '--relayer exec' option
--help Print usage
--input-mode string Input mode switches between raw request body passed into the exec command through STDIN and a JSON encoded full webhook event (see documentation for
format), must be used with '--relayer exec' option (default "body")
--no-agent Do not start relay agent after configuration
--relayer string Relayer type - 'default' HTTP (forward to HTTP servers) or 'exec' that executes commands on the current machine (default "default")
--timeout int Execution timeout in seconds, must be used with '--relayer exec' option. Set to 0 to never timeout (default 300)
-t, --type string Output type - internal or public (default "internal")
--ws Use WebSocket server as a transport (might evade certain firewalls)Here, to forward webhooks:
-b –bucket: supply bucket name to reuse existing one. Useful when invoking forward command for the same destination.
–no-agent: only configure bucket, input and output without starting an agent.
-t –type: is an output, defaults to internal.
Usage example:
$ relay forward --bucket webhook-demo http://localhost:8090/webhook
Forwarding:
https://my.webhookrelay.com/v1/webhooks/5e722a5e-f3d9-4eec-9e9f-79f1158e4b10 -> http://localhost:8090/webhook
Starting webhook relay agent...Another forward mode is to execute commands on your machine, to do that, use:
-b –bucket: supply bucket name to reuse existing one.
–relayer: use ‘exec’ relayer type to execute commands.
–command: command to execute, for example ‘python’, ‘bash’, ‘node’ and pretty much any other executable on your computer.
–input-mode: by default only request body is passed through stdin into the executed command, use ‘json’ to retrieve body, headers, method, query and additional bucket/input metadata.
All additional arguments passed to the forward command will be passed as arguments to the executed command:
relay forward --bucket my-bucket-name --relayer exec --command python my-script.py my-first-arg my-second-argConnect
Connect command automatically creates tunnel configuration and starts two-way request streaming:
$ relay connect -h
Usage: relay connect [OPTIONS] [DESTINATION]
Connects supplied destination to the public endpoint
Options:
--auto-generate Auto generate certificates if not supplied
--crt string Certificate file for TLS termination (optional)
-c, --crypto string To enable HTTPS endpoints for your tunnels use 'flexible', 'full', 'full-strict', 'tls-pass-through' (default "off")
--ddns-token string DuckDNS token, retrieve yours at https://www.duckdns.org/
-d, --destination string Destination (where the requests should be routed)
--help Print usage
-H, --host string Preferred host for the tunnel
--key string Key file for TLS termination (optional)
-m, --minify Minify content
-n, --name string Tunnel name
--no-agent Do not start relay agent after configuration
-p, --password string Password for basic auth (optional)
--protocol string Protocol (http, tcp) (default "http")
-r, --region string Region to connect tunnel daemon to
--rewrite-host-header string Rewrite host header
-s, --subdomain string Preferred subdomain for the tunnel
-t, --token string Authentication token
-u, --username string Username for basic auth (optional)Here:
-r, --region string: is a tunnel region. Select your region based on your location (example: eu, us-west, au)-d, --destination: is a destination to connect to.--no-agent: only configures tunnel without starting an agent.-p --password: is a password for the basic authentication.-u --username: is a username for the basic authentication.-t --token: is a token for the token authentication.-s --subdomain: is an optional parameter for preferred subdomain. If not supplied - random subdomain will be generated.
Usage example:
$ relay connect https://localhost:9400
Connecting:
http://f7ayb97wmq2fldenbyenxs.webrelay.io <----> https://localhost:9400
1.512048961831163e+09 info client starting {"version": "develop"}
1.5120489620960093e+09 info adding HTTP tunnel f7ayb97wmq2fldenbyenxs.webrelay.io ---> https://localhost:9400
1.512048962096073e+09 info tunnel proxy configuration updatedDiscovering other commands
To view other command in the CLI, use `--help` flag:
relay --helpExample output:
$ relay --help
Usage: relay COMMAND

Management Commands:
bucket Manage buckets - used to group inputs and outputs together
domain Manage domain reservations - reserved domains can later be used for bucket inputs or tunnel hostnames
function Manage functions - used to transform webhooks and writing custom plugins
ingress Manage ingresses - reverse tunnels for Kubernetes
input Manage inputs - your personal endpoints to receive webhooks
output Manage outputs - destinations where requests are relayed
token Manage tokens - required for API (OAuth users) and webhook streaming connections
tunnel Manage tunnels - bidirectional connections that expose internal services
Commands:
connect Connects supplied destination to the public endpoint
diagnostics Perform relay agent diagnostics
forward Create forwarding configuration (automatically creates bucket, input endpoint and output destination). If destination and bucket aren't specified - starts a relay for all endpoints
login Log in to a Webhook Relay service. Get your token key & secret pair here: https://my.webhookrelay.com/tokens.
