Synerise enables you to collect data from various sources and create advanced analyses based on this data. In short, Synerise enables you to gain insights from your data as well as create segments. The power of Synerise is that not only it allows you to gather, process and analyze data but also it lets you reuse it in the external sources. In this use case, you will use the native Facebook integration in Automation Hub to send a group of customers who were active in the web and mobile channels during last 30 days to Custom Audience. ## Prerequisites --- - [Generate the system user access token in Facebook](https://developers.facebook.com/docs/audience-network/optimization/report-api/system-user/); as the `scope` value, select `ads_management`. - [Create Custom Audience in Facebook](https://developers.facebook.com/docs/marketing-api/reference/custom-audience/). ## Process --- To send Custom Audience, follow the steps listed below in the following order: 1. [Create a segmentation of customers](/use-cases/send-custom-audience-webhook#create-a-segmentation) who are the most active in the web and mobile channels during last 30 days. 2. [Create a workflow](/use-cases/send-custom-audience-webhook#create-a-workflow) in which you will send the group of customers to Custom Audience in Facebook. ## Create a segmentation --- As the first part of the process, create a group of customers who were active in the mobile and web channels during last 30 days. The segmentation includes only customers with an email address. In the further part of the process, this group will be exported to Custom Audience in Facebook.

You must always narrow down the segmentation to customers who have an email address or a phone number.

1. Go to

**Decision Hub > Segmentations > New segmentation**. 2. Enter a meaningful name of the segmentation. 3. Click **Choose filter**. 5. From the dropdown list, select the **session.start** event. 4.

## Create a workflow --- In this part of the process, create a workflow for the group of customers you created in the [previous step](/use-cases/send-custom-audience-webhook#create-a-segmentation). This workflow sends the group of customers to Custom Audience in Facebook. ### Choose the segmentation of customers 1. Go to
