Traffic Log

How to read the log

The Traffic Log lets you inspect your app's HTTP/HTTPS traffic in real time.

The traffic log screen, showing a list of HTTP requests with their method, URL, status code, and type

Column	Description
Method	HTTP method (GET, POST, PUT, DELETE, etc.)
URL	Request URL
Status	Response status code (200, 404, 500, etc.)
Type	Requests that a mock was applied to are labeledMock
Time	Request timestamp

Tip: Requests that match a mock rule are labeled Mock. Regular requests have no special label.

Request / response details

Click a log entry to open the detail panel.

Request

URL (including query parameters)
Headers

Headers
Body (JSON/text/HTML)

Filtering

Search filter

api/users

Ignored domains

You can ignore requests from specific domains. Configure this from Data Management Settings in the sidebar.

# Example ignored domains
analytics.google.com
crashlytics.google.com
firebaseinstallations.googleapis.com

You can also add a domain by right-clicking an entry in the traffic log and selecting "Add to ignored domains".

Clearing the log

Use the clear button at the top of the log list to delete all currently displayed logs.

Create a rule from a log

You can create a mock rule directly from captured traffic.

The Create Rule button in the detail panel; clicking it auto-generates a mock rule from the traffic log

In the Traffic Log, click the request you want to mock.

Click the Create Rule button in the detail panel.

The URL pattern, method, response headers, and response body are filled in automatically.

Edit the settings as needed, choose a destination folder, and save.

Tip: Editing the URL pattern to add a wildcard makes it match similar requests too.
Example: /api/users/123 → /api/users/*

Export / import

You can save the traffic log to a file in .har (HTTP Archive) format. HAR is a W3C standard format and can also be opened in tools such as Chrome DevTools and Proxyman.

Save it as a .har file

You can view a saved .har file by dragging and dropping it onto the Mimicry app or double-clicking it.
