HAR Import & Export

APXY supports the HAR 1.2 specification  for exchanging traffic data with other tools. Export your captured traffic to share with teammates or import HAR files from browser DevTools, Charles Proxy, or other tools for analysis in APXY.

Export

CLI

apxy logs export-har writes HAR 1.2 JSON to stdout. Full options are in CLI Reference → Traffic.

Quick example:

apxy logs export-har > recording.har

Web API

GET /traffic/export/har

Returns a HAR JSON file as an attachment download.

Import

CLI

apxy logs import-har loads a HAR file into a har_import session. See CLI Reference → Traffic.

Quick example:

apxy logs import-har --file ./recording.har

Imported traffic is stored under a har_import session for easy identification.

Web API

POST /traffic/import/har

Accepts the HAR file as multipart form data or raw JSON body. Maximum file size: 50 MB.

Imported entries are tagged with a har_import session.

Use Cases

Share a bug reproduction

Export the traffic that demonstrates a bug and attach the HAR to a ticket.

Analyze browser recordings

Record traffic in Chrome DevTools (Network tab → Export HAR), import into APXY, then use SQL Queries or the Traffic viewer for deeper analysis.

Migrate from another proxy tool

Export a HAR from Charles Proxy, Fiddler, or mitmproxy and import it into APXY with apxy logs import-har.
