First time web hook

Ok so i have this web forum

This is what the web hook generated for me

void loop() {
  // Get some data
  String data = String(10);
  // Trigger the integration
  Particle.publish("Irrigation", data, PRIVATE);
  // Wait 60 seconds

void setup() {
  // Subscribe to the integration response event
  Particle.subscribe("hook-response/Irrigation", myHandler, MY_DEVICES);

void myHandler(const char *event, const char *data) {
  // Handle the integration response

how do i get the values from the forum to use in my code as a variable?
For some reason i cant rap my head around this one HELP

The HTTP response received from the webhook url

The HTTP request sent to the webhook url

GET /Irrigation/config/setup.php?zone=&run_time=&run=&when=&event=Irrigation&data=test-event&published_at=2020-12-17T21%3A28%3A50.363Z&coreid=api HTTP/1.1
User-Agent: ParticleBot/1.1 (
Connection: keep-alive

The source event that triggered the webhook

“name”: “Irrigation”,
“data”: “test-event”,
“ttl”: 60,
“published_at”: “2020-12-17T21:28:50.363Z”,
“coreid”: “api”

First you could add this to your handler

  Serial.printlnf("%s: %s", event, data);

and see what you get in the response.
