Zillow Integration

Track the estimated value of a property in the US



Back to Integrations



Retrieve property value data for most real estate properties throughout the US. Zillow provides its own proprietary “Zestimate” which incorporates public and user-submitted data, taking into account housing data, location, and market conditions.

Retrieving the latest property value from Zillow is a quick, three-step process.

1. Sign up for your own Zillow User ID and Password. Ensure you’ve checked off, “Home Valuations API” as part of the sign up process. This will ensure your ID is able to retrieve Zestimate data.

2. After signing up, you will receive your zws-id which you will store as your Zillow user ID and then store the password you used to sign up on Zillow as your password in the Hydrogen Integrations Admin.

3. Next, you will need to create an aggregation_account in Nucleus which has a category value of “Property” along with the following fields in the metadata:

address_line1
address_line2
city
state
postalcode
country

To create a property value which can be tracked, you will take the newly created aggregation_account_id and call POST /integration/v1/property_value.

Once we have the property linked to Zillow, you can use the following endpoint to retrieve the latest property value each day:
GET /integration/v1/aggregation/balance/{aggregation_account_id}.
