In Google Security Command Center: Sending notifications via Google Cloud Functions

1. Enable finding notifications for Pub/Sub with the following guide: https://cloud.google.com/security-command-center/docs/how-to-notifications#create-notification-config

2. Create following function example in Google Cloud Functions. Make sure to replace [WEBHOOK_URL]with the Url generated in this step.

Go

import (
	"context"
	"log"
	"net/http"
	"github.com/go-resty/resty/v2"
)

type PubSubMessage struct {
	Data []byte `json:"data"`
}

func WebhookPubSub(ctx context.Context, m PubSubMessage) {

	// Send the webhook request with the Pub/Sub message as the content
	webhookURL := "[WEBHOOK_URL]"

	client := resty.New()
	resp, err := client.R().
		SetHeader("Content-Type", "application/json").
		SetBody(m.Data).
		Post(webhookURL)
	if err != nil {
		log.Printf("Error creating webhook request: %v", err)
		return
	}

	// Check the webhook response
	if resp.StatusCode() != http.StatusAccepted {
		log.Printf("Webhook request failed with status code: %d", resp.StatusCode())
