Making an API call is really easy. All you need is:
There are 3 main APIs each take exactly the same parameters as either POST or GET data:
REAL-TIME CLEAN (ListWise Premium Plan Users Only): https://api.listwisehq.com/clean/realtime.php
The real-time clean API does the FULL ListWise cleaning processing in real-time. This is the same level of thorough cleaning as when you upload email lists into the ListWise application. This API is best for online registration, opt-in and signup forms – that require an instant verification of a single email address. Using the real-time API can save you from many problems and limits the need to re-clean your data in the future. This API will cost you 1 credit for each unique email request.
DEEP CLEAN: https://api.listwisehq.com/clean/deep.php
The deep clean API does the FULL ListWise cleaning processing, with a delayed result. This is the same level of thorough cleaning as when you upload email lists into the ListWise application. This API is best for cleaning email addresses in bulk. Unlike, the REAL-TIME CLEAN, the result is not immediate. You will need to call back the API to get the email clean result, after a few minutes. This API will cost you 1 credit for each unique email request.
QUICK CLEAN: https://api.listwisehq.com/clean/quick.php
The quick clean API is 100% FREE (as long as you have an active ListWise account with at least 1 credit available). This API is guaranteed to give you a result within 1000ms so is excellent for any place where you need a near instant validation of an email.
The quick clean API current performs the following email checks:
Address syntax and RFC checks, Domain checks (DNS and MX Servers), Typo fixing, Spam-trap checking, Free-mail checking and No-reply checking. It does not, however, do a real-time SMTP handshake with the email provider to check the validity of each individual email address. So the result would not be as accurate as the DEEP CLEAN or REAL-TIME clean.
All APIs return JSON format with the following fields:
|The email address being cleaned (may be different from the original email passed in for example if typo’s have been fixed)|
Additional statuses for the Real-Time API only.
|free_mail||yes / no: this address is a free-mail address|
|typo_fixed||yes / no: this address has had typo’s fixed|
|error_code||1: Not enough parameters|
2: Invalid user
3: No credits available
4: API communication error
|error_msg||error message matching the error_code|
