# Platform 161 setup for Data Activation

The Data Activation connector for Platform161 enables you to transmit user lists (audiences/segments) to Platform161's demand-side platform. This integration allows you to define your audiences in the Data Activation and synchronize them with Platform161 segments for targeted advertising campaigns.

Key features:

- Platform161 is used as a Demand Side Platform (DSP)
- Define audiences in the Data Activation and provide an identifier for the Platform161 segment you want to synchronize
- The integration is real-time
- Very user-friendly, standardized, and manageable
- Use the full platform functionality to segment visitors with specific requirements not possible in pixel-based integrations

## Before you begin

Before configuring the Platform161 connector, you need:

- A Platform161 segment ID
- A cookie sync (template) implemented

## Instructions

### Step 1: Configure cookie sync

Follow these steps to set up cookie sync:

1. In Data Activation, navigate to **Tags** and select **Pages**.
2. On the Global path, click the **+ button** to create a new tag.
3. In the popup window, search for **Relay42 data**.
4. Click the **Relay42 data** icon to reveal the options to the right. Find **Cookie sync** in the list and click **Select Variant**.
5. In the **Configure template** step, select **Platform 161** from the list of partners to sync with, and give the tag a name. Complete the remaining steps, such as rule setup, and save.
6. Publish the tag to your desired environment in **Tags** → **Publishing**.

### Step 2: Configure destination

1. Configure a Platform161 partner instance in the **Import/Export** section.
2. Configure and publish a cookie sync for Platform161.
3. Add the Platform161 integration to an existing or new audience and provide the segment ID you want to transfer data to.

### Step 3: Add the destination connector to an Audience/Journey

1. On the Data Activation platform, select **Audiences** in the left-side navigation bar.
2. Configure the criteria users should meet to become part of the audience in step 1.
3. Add your Platform 161 connector in step 2 of the audience setup.
