Tracking by API key, user ID, endpoint

Tracking by API key, user ID, endpoint

To understand customer behavior and system integrations, it is important to accurately track every API request. We implement a flexible and scalable mechanism for tracking by API key, user ID and endpoint'y. This allows you to analyze in detail:

• which clients use the API most actively,
• which routes are congested,
• which API versions cause errors or slowdowns.

What can be tracked

Parameter	Description
API key	Who makes calls, where the load comes from
User ID	Individual activity of each user or integrator
Endpoint	Specific API routes, their popularity and stability
API version	Which versions are used, where compatibility is maintained, or where errors occur

What tracking gives

Determination of bottlenecks and refueling points
Detection of harmful activity or DDoS
Third-Party Service API Usage Audit
Optimization prioritization for real loads
Diagnosing unstable integrations

How it is implemented

Middleware logging layer at the gateway or backend level
Structured log storage broken down by token, user, endpoint
Integration with APM and log analytics systems (Grafana, Kibana, Datadog)
Configuring Alerts for Abnormal Key or User Behavior
Support for aggregation and export to CSV/JSON/Prometheus

Business applications

SLA calculation and itemization per partner
Transparent API usage reporting
Fast debugging of problematic integrations
Reduce incident and bug time

Where especially critical

API for payment and financial services
Gaming platforms with active users
Mobile Applications and Client/Server Systems
API Partner Access Platforms (B2B)

Accurate tracking is the basis for stable API operation. We implement solutions that allow you to see who is using your API at any time, how and why, and respond in time to changes in customer or system behavior.
