API Callback Feature

The new callback feature for the Listwise API allows you to set a URL for us to send data to each time an address has been through a 'Deep Clean'. We will make an HTTP POST to this URL and pass the same JSON string that the Deep Clean API returns. This is to help improve your Listwise API processing so you don't have to repeatedly call the API to check the status.

To set the callback URL please log into your ListWise account and go into the Settings tab. Inside Settings you will find 'API Credentials' in the left hand menu. You can set your Callback URL here. Once set you can remove the URL at any time.



ListWise is the world's simplest and most accurate email list cleaning solution. ListWise intelligently cleans your list, validating every email, getting rid of duplicates and potential bounces and gives you a clean, fresh list that you can then use for your email marketing efforts.
