# Create a ROAS campaign

> Use the Unity User Acquisition Dashboard to set up a Return on Ad Spend (ROAS) campaign.

Refer to the following instructions to create a Return on Ad Spend (ROAS) campaign in the Unity User Acquisition Dashboard.

## Prerequisites

Before you set up your ROAS campaign, ensure that your [organization budget](/user-acquisition/billing/add-funds.md) has funds.

## Create a ROAS campaign in the User Acquisition Dashboard

To create a new ROAS campaign, complete the following steps in the User Acquisition Dashboard:

1. From the **Campaigns** page, select **Create** to enter the campaign creation flow.
2. Select **Return on Ad Spend** as your campaign goal.
3. In the **ROAS-specific settings**, choose your [optimization type](./intro-to-roas-campaigns#optimization-types) from the following options:
   * **In-app purchases**: Target users predicted to make in-app purchases.
   * **Ad revenue**: Target users predicted to engage with in-app ads.
   * **Hybrid**: Target users predicted to both make purchases and engage with ads in your app.
4. Select the **Optimization Window** for your campaign. Refer to the [Introduction to ROAS campaigns](./intro-to-roas-campaigns#optimization-windows) for details on which optimization types support which windows.
5. Name your campaign and select **Create**.
6. To launch your campaign and start the [Learning phase](./intro-to-roas-campaigns#learning-phase), configure the required campaign details.

   > **Note:**
   >
   > Each optimization type has required post-install events. When you integrate your preferred Mobile Measurement Partner (MMP) and create attribution links, ensure that you pass the required post-install event data for your selected optimization type. The dashboard lists the required event type in the **Attribution** setup section.
