Each API call is a potential source of important information. To ensure reliability, security and quick diagnostics, we implement detailed logging of incoming and outgoing API requests, including parameters, headers, body, response status, errors and technical details.
This log system allows you to track system behavior in real time, audit users or external services, and speed up debugging in case of any failures.
What we log
| Event type | What is fixed |
|---|---|
| Incoming requests | Method, endpoint, parameters, IP, headers, body |
| Outgoing responses | Response Code, Body, Headers, Runtime |
| Errors and exceptions | Type, description, stack trace, point of origin |
| Authorization | Token, user, validation result |
| Technical metrics | Delays, load, call frequency, retries |
Technical implementation
JSON logging for automated processing- Integration with log storage systems (ELK Stack, Loki, PostgreSQL)
- Support for logging by levels: INFO, DEBUG, ERROR, WARN
- Ability to filter by endpoint, date, code, user
- Configuring Alerts for Specific Errors or Response Times
Advantages for the team
Quickly isolate problems and failures- Audit of all actions: who, what, when called
- Real-World API Performance Analysis
- Ability to restore event context
- An indispensable tool for technical support and DevOps commands
Where especially important
Projects with transactions, financials, user data- Platforms with external APIs and many calls
- Complex architectures with microservices or distributed logic
- Integrations where reliability and control of all communications is important
Logging calls, answers and errors is not just a record of data, but the basis of control and quality of API integration. We capture everything that happens so you can react quickly, scale confidently and work reliably.
