• Head over to the Google Cloud Console.
• Either create a new project or pick one you already have.
• Make sure to enable the “Cloud Functions” API for your project.
• If you haven't set up billing yet, you'll need to do that since Cloud Functions need an active billing account.

• Grab the Google Cloud SDK and install it.
• Fire up your terminal and run gcloud init to initialize the SDK. Authenticate yourself and set the project you're working on.

• Make a new folder for your function, something like my-cloud-function.
• Inside this folder, create an index.js file for your function’s code and a package.json for dependencies.

// index.js
exports.myFunction = (req, res) => {
  const message = req.query.message || req.body.message || 'Hello World';
  res.status(200).send(message);
};

// package.json
{
  "name": "my-cloud-function",
  "version": "1.0.0",
  "dependencies": {
    "express": "^4.17.1"
  }
}

• Deploy the function to Google Cloud using this command in your terminal:

gcloud functions deploy myFunction --runtime=nodejs14 --trigger-http --allow-unauthenticated

• Once the deployment is done, jot down the URL provided for your function. You'll need this URL to hook up with WeWeb.

• Log into your WeWeb account and open the project you want to link with Google Cloud Functions.
• Navigate to the “Workflows” section of your project.

• Create a new Workflow and add an action step to make an HTTP request.
• Set the request method to GET or POST depending on what your function needs.
• Enter the URL of your Google Cloud Function.
• Configure any necessary headers and parameters.

• Trigger the workflow in WeWeb to make sure the Google Cloud Function is called correctly.
• Check both the WeWeb and Google Cloud Console logs to verify that the function runs as expected.

Following these steps will integrate Google Cloud Functions with WeWeb, allowing dynamic content and interactions driven by serverless functions.
