Validating large and complex JSON payloads in Oracle Integration Cloud (OIC) can often be time-consuming and error-prone—especially when dealing with deeply nested structures or mandatory fields.

In this video, we’ll walk you through a simple yet powerful JavaScript-based validation technique to solve this challenge efficiently.

✅ What you’ll learn:

• How to understand and navigate a complex JSON payload structure.

• Why native OIC expression-based validation can be limiting for large payloads.

• How to use JavaScript action in OIC to perform structured, rule-based validation.

• How to identify and report missing or empty mandatory fields with clean, readable code.

• Real-time validation with better performance and maintainability for large payloads.

By the end of this video, you’ll be able to:

• Confidently work with large JSON structures.

• Implement custom validation logic inside your integrations.

• Handle payload issues early, improving reliability and reducing errors downstream.

🔧 Whether you're an integration developer or just getting started with OIC, this approach will make your payload validation cleaner, faster, and more scalable.
