What is Zillow API Integration?

An API (Application Programming Interface) allows software programs to communicate. A Zillow API integration would let your CRM automatically pull property data from Zillow without manual copy-paste.

What investors want from Zillow integration:

Auto-import saved search results
Get new listing alerts in real-time
Pull property details (price, photos, specs)
Track price changes automatically
Import to CRM without manual work

The Zillow API Situation in 2026

Here's what you need to know:

Timeline

Before 2021: Zillow offered public API access for developers
2021: Zillow shut down public API to focus on their own products
2022-2024: No official API available to third parties
2025-2026: Authorized integrations through official partnerships only

How to Integrate Zillow Without an API

Since Zillow's public API is discontinued, here are your actual options:

✓ Option 1: Use OnMarket CRM (Recommended)

OnMarket CRM has authorized methods to import your Zillow alerts and saved searches automatically. No technical setup required—just connect your account.

• Works with Zillow's current platform (2026)
• Legal and authorized integration
• No coding knowledge required
• 5-minute setup

~ Option 2: Web Scraping (Technical, Risky)

Some developers scrape Zillow's website directly. This requires coding skills and violates Zillow's Terms of Service.

• Requires Python/JavaScript knowledge
• Against Zillow's TOS (can be blocked)
• Breaks when Zillow updates their site
• Not recommended

✗ Option 3: Manual Export (Slow, Not Scalable)

Download Zillow data manually and import to your CRM. This defeats the purpose of automation.

• Extremely time-consuming
• Human error prone
• Can't scale beyond a few properties
• Defeats automation benefits
