How do I see which suppliers make up the iVectorOne search?

Adding the emailLogsTo parameter to your search request will email the specified address a copy of each underlying supplier search request that relates to the iVectorOne search that has been performed

For example:

https://api.ivectorone.com/v2/property/search?ArrivalDate=2023-05-21&duration=1&properties=374839&rooms=(2,0,0)&emaillogsto=helpdesk@ivectorone.com
