Publishers can use the OpenRTB burl (billing notify URL) field to notify Index Exchange (Index) and DSPs when an ad renders on the user’s device and becomes billable. Using the burl field standardizes the billing notifications sent to DSPs and helps reduce reporting discrepancies. To use burl with Index, your software development kit (SDK) or server must support HTTP 302 redirects.
To enable burl with Index, contact your Index Representative.
Index accepts burl for Media Owners using either server-side or client-side beaconing:
Server-side beaconing: You send Index a notification when a billable event has happened on the device or app, initiated from your ad server or SSAI. For more information, see Sending billable event notifications (burl) to Index through server-side beaconing.
Client-side beaconing: You send Index a notification when a billable event has happened from your site or app code. For more information, see Sending billable event notifications (burl) to Index through client-side beaconing.
