Impressionwise Email Verification and Spam Trap Removal


Bots API Overview (Coming soon...!)

Non-Human, Invalid Traffic API Overview

Protect against high-risk traffic sources (bad actors) and guard against ad-fraud in the form of Non-Human Invalid Traffic (IVT). Our sophisticated machine learning algorithms identify traffic originating from botnets, data center traffic, click farms, proxies, malicious script injectors and hijacked devices, , delivering the highest quality reach.

Our invalid traffic API can be seamlessly integrated into your signup or onboarding process with just a single request. This high-speed service is designed for real-time, verification of the IP address or traffic attempting to connect thru to your landing page.

Structure and Definition for Inbound Submissions

Our API requires you to authenticate each individual request. Below is an example of a basic URL structure request, just substitute with the provided account, associated password along with any optional parameters.

While it is uncommon some replies to take an excessive amount of time to respond (sometimes more than 5 seconds). Due to this possible condition, you will receive a result code of RETRY. Upon reception of this response, please continue your HTTP submissions thru to completion of the entire data set to be submitted.. Once complete, please retry any/all responses with "RETRY" or as shown below:
