Hosted Data Layer was created to offer a cloud-based solution for supplementing the data layer object of your website. This allowed valuable data that was stuck in offline or server-side systems to become accessible to your web pages in real-time.
Until now, HDL was limited to use with the Hosted Data Layer extension and for the sole purpose of supplementing the on-page data layer. With this new release, HDL is being expanded to support JSON files. JSON is a versatile data format that is used in a wide variety of internet applications and integrations between systems.
How Does It Work?
Use the Hosted Data Layer API to upload your JSON files, then access those files with the corresponding URL on the Tealium Multi-CDN.
