​
How Integrations Work

Metlo integrations work by:
  1. Capturing API traffic - Intercepting HTTP requests and responses
  2. Extracting metadata - Gathering headers, parameters, body data
  3. Sending to collector - Asynchronously transmitting data to Metlo
  4. Analysis - Detecting sensitive data, vulnerabilities, and anomalies
All integrations are designed to have minimal performance impact on your applications.
