# Add an Amazon Bedrock prompt to a flow app
<a name="add-prompt-to-prompt-flow-app"></a>

In this procedure, you add a prompt to an existing [flow app](create-flows-app.md).

**To add a prompt to a flow app**

1. Navigate to the Amazon SageMaker Unified Studio landing page by using the URL from your administrator.

1. Access Amazon SageMaker Unified Studio using your IAM or single sign-on (SSO) credentials. For more information, see [Access Amazon SageMaker Unified Studio](getting-started-access-the-portal.md).

1. If the project that you want to use isn't already open, do the following:

   1. Choose the current project at the top of the page. If a project isn't already open, choose **Select a project**.

   1. Select **Browse all projects**. 

   1. In **Projects** select the project that you want to use.

1. Choose the **Build** menu option at the top of the page.

1. In **MACHINE LEARNING & GENERATIVE AI** choose **My apps**.

1. In **Apps** choose the flow app that you want to add the prompt to.

1. In the **flow builder** pane, select the **Nodes** tab.

1. From the **Orchestration** section, drag a **Prompt** node onto the flow builder canvas.

1. In the the flow builder, select the Prompt node that you just added. 

1. In the **flow builder** pane, choose the **Configure** tab and do the following:

   1. For **Node name**, enter a name for the Prompt node. 

   1. For **Prompt** in the **Prompt details** section, select the prompt that you want to add.

   1. For **Version**, select the version of the prompt that you want to add.

   1. (Optional) In **Select guardrail** select an existing guardrail. For more information, see [Safeguard your Amazon Bedrock app with a guardrail](guardrails.md).

   1. If you want to identify specific data from the upstream node that the prompt should use, change the value in **Expression**. For more information, see [Define inputs with expressions](flows-expressions.md). 

1. The circles on the nodes are connection points. For each variable, draw a line from the circle on the upstream node (such as the **Flow input** node) to the circle for the variable in the **Input** section of the prompt node. 

1. Connect the **Output** of the prompt node to the downstream node that you want the prompt to send its output to. The flow should look similar to the following image:

1. Choose **Save** to save your changes.
