# Understanding Field Hydration in Propexo's Unified Data Model

Propexo integrates with a wide range of property management systems, each with its own data structures. As a result, fields in the unified data model are hydrated depending on the capabilities and configuration of the source PMS. This article outlines the process for determining whether a field is hydrated, and provides guidance on when to escalate to support for missing data requests.

## Where to Find This in the Docs

To view the PMS source for any field:

1. Go to the [**Propexo API Docs**](https://docs.propexo.com/).
2. Navigate to the **specific PMS** you are using.
3. Navigate to the **relevant endpoint** (e.g., `/residents`, `/leases`, `/transactions`).
4. Look at the **response schema** – each field includes a **"PMS Source"** or **"Backed by"** note showing where it's pulled from in the PMS.

## Example

Let's say you're using the `/leases` endpoint and want to know where the `deposit_date` value is coming from.

1. In the Propexo documentation, go to **API Reference**.

2. Select your **PMS** and then click on the relevant endpoint, in this case, **"Get All Leases"**.

3. Scroll to the **Response** section, and expand the `results` object to view the full list of properties returned by the Propexo API.

Each field populated from the PMS will include a note showing which **PMS Method** Propexo uses to retrieve that data. If a field is not hydrated, there will be a message indicating this.

## When to Contact Support

If you have a piece of data that is missing and the field **does not have this message** in our documentation, please reach out to support.
