JSON Monitor

Available in Starter plan and above

What is a JSON monitor?

JSON (JavaScript Object Notation) is a standard format for data interchange on the web. It’s widely used in APIs and web services for its efficiency in organizing data and ease of parsing.

A JSON monitor automatically tracks changes in JSON data at a given URL and sends alerts when the content, structure, or values change. This is useful for monitoring:

• API responses and endpoints
• E-commerce product data
• News feeds and aggregators
• Financial services data
• Social media platform APIs
• Real-time data feeds

URL parameters

JSON monitors automatically load URL parameters (key-value pairs) if present in the URL.

Click Add Query Param to add additional parameters or headers as needed.

Supported HTTP methods

• GET — Retrieves data from a resource (most common for JSON monitoring)
• POST — Creates a new resource
• PUT — Replaces an existing resource
• PATCH — Partially modifies a resource
• DELETE — Removes a resource
