Setting Up Context Support Using JavaScript
12
• Web apps request context support using
AmbientWeb’s Façade REST API.
22
Dynamix downloads and installs associated plug-ins in the background
Web apps add context support for required context types
11
33
If necessary, Web apps trigger context requests (scans or interactions)

Handling Context Events
• Context events are sent to apps using
AmbientWeb’s Event REST API
