Deploy Google Cloud Functions as webhooks to capture event-based data from GitHub, Slack, or Hubspot

Cloud Functions are used to receive and process webhook requests from external sources such as GitHub, Slack, and HubSpot, which can trigger various actions like sending real-time alerts or storing data for later use. Cloud Functions provide a cost-effective way to handle low volumes of events with pricing unbeatable for serverless services. The setup involves creating a cloud function with an HTTP trigger, configuring the webhook URL in the external source's settings, and integrating the application with the desired platform. For example, setting up a GitHub webhook sends relevant data from pull requests or commits to BigQuery, while a Slack webhook processes messages sent in a channel and stores them in BigQuery, and a Hubspot webhook triggers specific conditions within an automation workflow and sends data to BigQuery.
