Apologies for the broken link, we have recently consolidated library articles. Here is the correct link https://library.vuforia.com/content/vuforia-library/en/articles/Solution/How-To-Use-the-Vuforia-Web-Services-API.html#How-To-Check-for-Duplicate-Targets

Thanks,

Hi,

There is no sample code to check for duplicate image from PHP.  

https://developer.vuforia.com/library//articles/Solution/How-To-Check-for-Duplicate-Targets-using-the-VWS-API  link is NOT available.  

Please let me know if  there any way we can use this feature of duplicate image using Cloud Reco ?
