+# Google Cloud Function HTTP request Python example
+
+This folder contains a Google Cloud Function example in Python on Google Cloud Platform (GCP).
+
+It handles a Google Cloud Function that responds to an HTTP request.
+
+## Requirements
+
+* You must have a [Google Cloud Platform (GCP)](http://cloud.google.com/) account.
+
+* The code was written for Python 3 and Google Cloud Python Client Library.
+
+## Using the code
+
+* Access the Google Cloud console.
+
+* Create a Google Cloud Function:
+  * Name: `<CLOUD_FUNCTION_NAME>`
+  * Memory allocated: `256 MB`
+  * Trigger: `HTTP`
+  * URL: `https://<GOOGLE_CLOUD_REGION>-<PROJECT>.cloudfunctions.net/<CLOUD_FUNCTION_NAME>`
+  * Source code. You can use 2 options:
+    * Inline editor:
+      Edit the code of the `main.py` in the browser.
+    * ZIP upload:
+      Upload a ZIP file containing the `main.py` and `requirements.txt` files.
+      * ZIP file: `<ZIP_LOCAL_NAME>`
+      * Stage bucket: `<BUCKET_NAME_FOR_STAGGING>`
+  * Runtime: `Python 3.7 (Beta)`
+  * Function to execute: `http_request`
+  * Region: `<GOOGLE_CLOUD_REGION>`
+  * Timeout: `60 seconds`
+
+* Save the Google Cloud Function.
+
+  The function is deployed and run.
+
+* Test the function.
+
+  You can test it in 2 ways:
+  
+  * First way: Test the funcion functionality in the Google Cloud console.
+
+    Go to the `Function details` and select `Testing`.
+
+    Enter the `Triggering event` content:
+
+    {
+      "message": "Hello Peter!"
+    }
+
+    Click `Test the function`.
+
+    You should see the next message in the Google Cloud `console output`:
+
+    ```bash
+    Hello Peter!
+    ```
+
+  * Second way: Test the function with a browser.
+
+    Go to the URL: `https://<GOOGLE_CLOUD_REGION>-<PROJECT>.cloudfunctions.net/<CLOUD_FUNCTION_NAME>` using a browser.
+
+    You should see the response:
+
+    ```bash
+    Hello World!
+    ```
