Nango’s logs are comprehensive and give you a detailed picture of what happens in your integrations.

​
Our approach

Since integrations rely on third-party APIs, production issues are bound to happen. When you encounter a problem, great observability is the difference between a week-long needle-in-a-haystack hunt and a timely resolution. We built Nango’s logs based on three principles:
  • Comprehensive: Everything that happens in Nango for your integrations produces an “operation” in the logs
  • Detailed: Every operation and every log message contains detailed information about the integration, connection, and function. Error messages are as detailed as the external APIs allow.
  • Customizable: You can easily log your own messages from functions you write (learn more). To consume logs, you can either use our built-in interface or export them with our OpenTelemetry exporter

Overview of Nango logs

Logs are structured into:
  • Operations: High-level actions happening in your Nango account (e.g., sync executed, connection created, webhook processed)
  • Log messages: Nested in operations, these provide details on what happened (e.g., HTTP request executed, data validation warning, custom log message)
Nango provides detailed filtering and searching of log messages by integration, connection, operation type, status, etc. We recommend exploring the logs in your own Nango account under Logs.

​
Logs MCP tools (Beta)

The Management MCP server provides Beta tools for listing and filtering log operations and retrieving their messages from an MCP-compatible client. This helps LLMs investigate and fix integration issues automatically.

​
OpenTelemetry export

Nango supports exporting OpenTelemetry traces so you can monitor and analyze integration activity in your own observability stack. Use this for:
  • Advanced custom metrics
  • Advanced alerting and escalation paths (e.g., segment sync errors by customer account for customized escalation paths)

​
Supported operations

The following operations are exported as traces:
  • Sync executions
  • Action executions
  • Third-party API webhook executions
  • Proxied requests
If you need support for other operations please reach out. We can enable support for them.
