Setup guide

Workflow

How It Works

  1. Step 1

    Configure

    Generate proxies for your target country in the dashboard or via our REST API, down to state and city on Residential Light & Basic.

  2. Step 2

    Verify

    ZentisLabs routes your request through a real residential or mobile IP in the target geo.

  3. Step 3

    Report

    Your verification scripts capture status codes, screenshots and creative matches, all from a genuine in-market IP.
