# Consuming models via Flow

> Consume a deployed IXP Unstructured and Complex Documents model version in UiPath Maestro™ Flow through the Extract node.

The node sends a document to the model and returns the extracted fields for downstream nodes to use. For the full node reference, including the output structure and error handling, check [Extract node](https://docs.uipath.com/maestro/automation-cloud/latest/user-guide/node-extract) in the Maestro user guide.

## Prerequisites

Make sure you meet the following requirements:

* Your tenant has both the **IXP** and the **Document Understanding** services enabled.
* You have at least one of these:
  * **IXP Package Reader** role in IXP, so that the **To folder** option is visible when you deploy. For more details, check [Managing access](../overview/managing-access.md).
  * **IXP Models - Create** permission in Orchestrator in the folder where you deploy the model.
* You have access to the Orchestrator folder where the model is deployed.
* A model version is ready to be deployed using the **To folder** (preview) option. For more details, check [Publishing model versions](publishing-model-versions.md).

## Consuming a deployed model in Flow

To consume a deployed model version in Flow, proceed as follows:

1. In IXP, go to the **Deploy** tab and deploy your model version with the **To folder** (preview) option:
   1. Enable the **Deploy IXP model** option.
   2. Enter a **Deployment name**.
   3. From the **Location** dropdown list, select the Orchestrator folder.
   4. Select **Deploy**.
2. In your Flow project, open the node palette and go to **Document processing**, then **Extract**.
3. Select the model.
4. Add the model to the Flow canvas, which creates an **Extract** node bound to that model.
5. Configure the node in the properties panel.

**Result:** When the flow runs, the **Extract** node returns the extraction result at `$vars.<nodeName>.output`. To read individual field values, check [Reading the result](https://docs.uipath.com/maestro/automation-cloud/latest/user-guide/node-extract#reading-the-result).

:::note
IXP models used in Flow projects are onboarded to Solutions Management. When you publish and deploy a Flow solution that includes an IXP model to a new environment, the IXP model is packaged, migrated, and deployed along with the rest of the solution.
