How We Centralized Leads from Multiple Websites Using a Custom API in Zoho Creator

Marketing teams often run multiple websites, landing pages, and campaigns to generate leads. But when each website stores data separately, it creates scattered information and poor visibility for decision-making.

In this guide, we'll show you how we built a centralized lead collection system using a custom API in Zoho Creator that solved this problem for our client.

The Problem

Marketing teams running multiple websites face several challenges when it comes to lead management:

Common Issues

• Leads come from different sources: Each website, landing page, and campaign collects leads independently
• Each website stores data separately: No unified database means data is fragmented across multiple systems
• No single source of truth: Impossible to get a complete picture of all incoming leads
• Limited visibility for management: Decision-makers struggle to see:
  • Website-wise performance comparison
  • Lead volume trends
  • Campaign effectiveness
  • Overall lead quality by source
• Manual consolidation wastes time: Team members spend hours exporting, merging, and analyzing data from multiple sources

The Solution

We built a centralized lead collection system using a custom API in Zoho Creator.

Now, all websites send leads to one single place, regardless of where the lead originates.

How the Solution Works

1. Custom Lead API in Zoho Creator

We created a secure API endpoint in Zoho Creator that serves as the central intake point for all leads.

This API is responsible for:

• Receiving lead data: Accepts POST requests with lead information from any website
• Validating required fields: Ensures data quality by checking for mandatory fields like name, email, phone
• Storing leads in a single form: All validated leads are saved to one centralized Zoho Creator form
• Returning confirmation: Sends success or error responses back to the calling website

2. Websites Send Leads via API

Every website is configured to call the same API endpoint whenever a lead is captured.

Each request includes special parameters to identify the exact lead origin:

• Website name: Identifies which website the lead came from (e.g., "product-website", "service-landing-page", "blog")
• Campaign source: Tracks the marketing campaign (e.g., "google-ads-Q1", "email-newsletter", "social-media")
• Lead type: Categorizes how the lead was captured (e.g., "Contact Form", "Newsletter Signup", "Demo Request")
• Additional metadata: Any other relevant tracking information

This granular tracking helps identify exactly where each lead originated and which campaigns are performing best.

3. Centralized Lead Storage

All incoming leads are stored in a single Zoho Creator form with a clean and consistent data structure.

4. Website-wise Consolidated Reports

We built comprehensive management reports that provide instant visibility into lead performance.

Reports are grouped by:

• Website: Compare performance across different websites
• Campaign: Track which campaigns generate the most leads
• Date range: Analyze trends over time (daily, weekly, monthly)
• Lead type: Understand which capture methods work best

Management can instantly see:

• Which website generates more leads
• Daily, weekly, and monthly trends
• Campaign performance comparison
• Lead quality metrics by source
• Conversion rates across different channels

Conclusion

By introducing a custom API-based lead intake system in Zoho Creator, we transformed scattered lead data into a centralized, report-driven system that works seamlessly across multiple websites.

This approach not only solved the immediate problem of data fragmentation but also created a scalable foundation for future growth. As the business adds more websites, landing pages, or campaigns, they can simply integrate with the existing API without any additional complexity.

The result is a professional lead management system that provides real-time visibility, eliminates manual work, and empowers management to make data-driven decisions.
