+# Google Cloud Tasks Samples
+
+[![Open in Cloud Shell][shell_img]][shell_link]
+
+[shell_img]: http://gstatic.com/cloudssh/images/open-btn.png
+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/GoogleCloudPlatform/python-docs-samples&page=editor&open_in_editor=tasks/README.md
+
+This sample demonstrates how to use the
+[Cloud Tasks](https://cloud.google.com/tasks/docs/) client library.
+
+`create_http_task.py` is a simple command-line program to create
+tasks to be pushed to an URL endpoint.
+
+`create_http_task_with_token.py` is a simple command-line program to create
+tasks to be pushed to an URL endpoint with authorization header.
+
+## Prerequisites to run locally:
+
+Please refer to [Setting Up a Python Development Environment](https://cloud.google.com/python/setup).
+
+## Authentication
+
+To set up authentication, please refer to our
+[authentication getting started guide](https://cloud.google.com/docs/authentication/getting-started).
+
+## Install Dependencies
+
+To install the dependencies for this sample, use the following command:
+
+```
+pip install -r requirements.txt
+```
+
+This sample uses the common protos in the [googleapis](https://github.com/googleapis/googleapis)
+repository. For more info, see
+[Protocol Buffer Basics](https://developers.google.com/protocol-buffers/docs/pythontutorial).
+
+## Creating a queue
+
+To create a queue (named `my-queue`) using the Cloud SDK, use the following
+gcloud command:
+
+```
+gcloud tasks queues create my-queue
+```
+
+## Run the Sample Using the Command Line
+
+Set environment variables:
+
+First, your project ID:
+
+```
+export PROJECT_ID=my-project-id
+```
+
+Then the queue ID, as specified at queue creation time. Queue IDs already
+created can be listed with `gcloud tasks queues list`.
+
+```
+export QUEUE_ID=my-queue
+```
+
+And finally the location ID, which can be discovered with
+`gcloud tasks queues describe my-queue`, with the location embedded in
+the "name" value (for instance, if the name is
+"projects/my-project/locations/us-central1/queues/my-queue", then the
+location is "us-central1").
+
+```
+export LOCATION_ID=us-central1
+```
+
+### Creating Tasks with HTTP Targets
+
+Set an environment variable for the endpoint to your task handler. This is an
+example url:
+```
+export URL=https://example.com/task_handler
+```
+
+Running the sample will create a task and send the task to the specific URL
+endpoint, with a payload specified:
+
+```
+python create_http_task.py --project=$PROJECT_ID --queue=$QUEUE_ID --location=$LOCATION_ID --url=$URL --payload=hello
+```
