Webhooks demo for teaching purposes

Basic Usage Instructions

Version 1 (internal client)

Registration:

• Start server.go to provide webhook registry (localhost:8080/webhook)

• Start client.go (first review whether validation should be activated - see variable "validationLevel")

• Send post request to localhost:8080/webhook with body

{ "url": "http://localhost:8081/invokedUrl", "event": "POST" }

(Note: Take URL from console output when service is started - which deviates for validating version)

Invocation:

• Invoke localhost:8080/service with POST request

• Observe invocation of registered webhook

Version 2 (external client)

• Get webhook URL from https://webhook.site/

• Send post request to localhost:8080/webhook with body

{ "url": "url from webhook.site", "event": "POST" }

• Now invoke as describe in Version 1. The external webhook should be invoked.
