**Benefits of the Google Cloud Pub/Sub output connector**:

* Directly stream device data from akenza to **Google Cloud Pub/Sub** and subsequently process it in **Google Cloud Pub/Sub**
* Easily process **low-power device** data e.g. LoRaWAN device data in **Google Cloud Pub/Sub**
  {% endhint %}

In this tutorial, you will learn, how to send data to [**Google Cloud Pub/Sub**](https://cloud.google.com/pubsub/docs/overview). The following steps are explained in more detail:

1. [Setup a **Google Cloud Pub/Sub**](#1.-setup-a-gcp)
2. [Add an akenza service account](#2.-add-akenza-service-account)
3. [Setup a **Data Flow** in akenza ](#3.-setup-a-data-flow-in-akenza)
4. [Setup a subscription](#4.-setup-a-subscription)
5. [Useful Links](#5.-useful-links)

### 1. Setup a **Google Cloud Pub/Sub**

First, you will need to set up a project on the **Google Cloud Console**.

1.1 If you are new to Google Cloud, [create an account](https://console.cloud.google.com/freetrial) to evaluate how the products perform in real-world scenarios.

1.2 Set up a **Cloud Console project** in a PubSub section <https://cloud.google.com/pubsub>. Create or select a project and enable the **Pub/Sub API** for that project. You can view and manage these resources at any time in the [Cloud Console](https://console.cloud.google.com/).

1.3 Set up a topic where your data shall be sent to. Go to the Pub/Sub topics page in the Cloud Console. [Go to the Pub/Sub topics page](https://console.cloud.google.com/cloudpubsub/topicList) and select *Create a topic*.

In the **Topic ID** field, provide a unique topic name, for example, `MyTopic` and select *Save*.

### 2. Add an akenza service account

Navigate to your Project settings and select on **IAM** policy section. Select *+ Add* and paste the akenza publisher service account key. Give the role of a **Pub/Sub Publisher.**

### 3. Setup a Data Flow in akenza

Create a new **Data Flow** in akenza with Google Cloud Pub/Sub as output connector. Define a **Connector Name** and insert the **topic id** obtained from the project. Optionally use a custom payload.

[Create a new device](https://docs.akenza.io/akenza.io/how-to-create-a-working-environment/how-to-connect-a-device) using the Data Flow and start sending data.

### 4. Setup a Subscription

In your Pub/Sub section go to **Subscriptions**, select *Create Subscription*, give it a name, and select the previously created topic.

Following steps to view device data:

* Click on the created topic
* Scroll down to the bottom of the topic details
* There are three tabs, select **Messages**&#x20;
* Open the dropdown on the bottom "Select a Cloud Pub/Sub Subscription to pull messages from \*" and select the subscription previously created
* Click *Pull* to fetch the messages which can then be filtered in **Filter** options and sorted by various p
