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 forwardcommand - automatically configure tunnel with
relay connectcommand - manage 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:
1
relay login -k token-key-here -s token-secret-here
Copied!
- Environment variable option is very useful when automating things:
1
export RELAY_KEY=token-key
2
export RELAY_SECRET=token-secret
Copied!
Forward
Forward command automatically creates configuration and starts one-way request forwarding:
1
relay forward --help
2
3
Usage: relay forward [OPTIONS] [DESTINATION | COMMAND ARGS]
4
5
Create forwarding configuration (automatically creates bucket, input endpoint and output destination). If destination and bucket aren't specified - starts a relay for all endpoints
6
7
Options:
8
-b, --bucket string Bucket name (defaults to destination name if not supplied)
9
--command string Command to execute, must be used with '--relayer exec' option
10
--help Print usage
11
--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
12
format), must be used with '--relayer exec' option (default "body")
13
--no-agent Do not start relay agent after configuration
14
--relayer string Relayer type - 'default' HTTP (forward to HTTP servers) or 'exec' that executes commands on the current machine (default "default")
15
--timeout int Execution timeout in seconds, must be used with '--relayer exec' option. Set to 0 to never timeout (default 300)
16
-t, --type string Output type - internal or public (default "internal")
17
--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:
1
$ relay forward --bucket webhook-demo http://localhost:8090/webhook
2
Forwarding:

https://my.webhookrelay.com/v1/webhooks/5e722a5e-f3d9-4eec-9e9f-79f1158e4b10 -> http://localhost:8090/webhook

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:1
relay forward --bucket my-bucket-name --relayer exec --command python my-script.py my-first-arg my-second-arg

Connect
Connect command automatically creates tunnel configuration and starts two-way request streaming:
1
$ relay connect -h
2
3
Usage: relay connect [OPTIONS] [DESTINATION]
4
5
Connects supplied destination to the public endpoint
6
7
Options:
8
--auto-generate Auto generate certificates if not supplied
9
--crt string Certificate file for TLS termination (optional)
10
-c, --crypto string To enable HTTPS endpoints for your tunnels use 'flexible', 'full', 'full-strict', 'tls-pass-through' (default "off")
11
--ddns-token string DuckDNS token, retrieve yours at https://www.duckdns.org/
12
-d, --destination string Destination (where the requests should be routed)
13
--help Print usage
14
-H, --host string Preferred host for the tunnel
15
--key string Key file for TLS termination (optional)
16
-m, --minify Minify content
17
-n, --name string Tunnel name
18
--no-agent Do not start relay agent after configuration
19
-p, --password string Password for basic auth (optional)
20
--protocol string Protocol (http, tcp) (default "http")
21
-r, --region string Region to connect tunnel daemon to
22
--rewrite-host-header string Rewrite host header
23
-s, --subdomain string Preferred subdomain for the tunnel
24
-t, --token string Authentication token
25
-u, --username string Username for basic auth (optional)
Copied!
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:
1
$ relay connect https://localhost:9400
2
Connecting:
3
http://f7ayb97wmq2fldenbyenxs.webrelay.io <----> https://localhost:9400
4
1.512048961831163e+09 info client starting {"version": "develop"}
5
1.5120489620960093e+09 info adding HTTP tunnel f7ayb97wmq2fldenbyenxs.webrelay.io ---> https://localhost:9400
