# Fivetran Activations (formerly Census)
> Fivetran Activations, formerly Census, syncs modeled data from a warehouse or database into operational and customer engagement tools. MotherDuck is available as a source in Fivetran Activations, which means Activations can read from MotherDuck and sync selected data to supported activation destinations.
This is different from the [Fivetran MotherDuck destination](/integrations/ingestion/fivetran), which loads data from other sources into MotherDuck.

## How it works with MotherDuck

Fivetran Activations can use MotherDuck as a source for reverse ETL syncs into operational tools.

## Prerequisites

- A Fivetran Activations workspace or trial.
- A MotherDuck service token.
- Modeled tables or views in MotherDuck that contain the records you want to activate.

## Setup

1. In MotherDuck, create or copy a service token.
2. In Fivetran Activations, open **Sources**.
3. Select **New Source** and choose **MotherDuck**.
4. Enter the MotherDuck service token and connect the source.
5. Open **Syncs** and create a sync from the MotherDuck source to your target destination.

## Authentication and configuration

- Use a dedicated service token for Activations.
- Expose stable tables or views for activation syncs so field mappings remain consistent.
- Start with a limited audience or test destination object before enabling production syncs.

## Important notes

- Fivetran Activations uses MotherDuck as a source, not as a destination.
- Fivetran's docs note MotherDuck support through the Basic Sync Engine. Check the linked docs for current engine support before designing large activation workflows.

## Use cases

- Sync product-qualified leads or account scores from MotherDuck to CRM tools.
- Push modeled user segments from MotherDuck to marketing platforms.
- Activate customer event or enrichment data produced in MotherDuck.
