Add API traffic to Akto using HAR file upload

Learn how to uplaod API traffic data from HAR file to Akto


Akto needs your staging, production or other environment's traffic to Discover APIs and analyze for AP misconfiguration. It does so by connecting to one of your traffic sources. If you don't have access to staging or production environment, you can create API inventory using HAR file upload.

Note that traffic from HAR File upload won't be automated like the native cloud connectors.

HAR File Upload is recommended for Akto Open source or free tier only. For an automated inventory, you will want to use other automated traffic connectors.

Troubleshooting Guide

I uploaded 100 APIs, but I can only see 85 of them in the dashboard. Where are the missing APIs?

Akto processes and displays only APIs that have received a 2xx series status code in their HTTP responses. If an API request did not receive a 2xx status code (e.g., 3xx, 4xx, or 5xx), it may not appear in the dashboard.
