Attribution-Reporting-Eligible
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The HTTP Attribution-Reporting-Eligible
request header indicates that the corresponding response is eligible to register an attribution source or trigger.
This header is never set manually and is instead sent by the browser in response to various HTML element or JavaScript request settings. Depending on the allowed registrations specified in the Attribution-Reporting-Eligible
value, the server is expected to respond with either an Attribution-Reporting-Register-Source
or Attribution-Reporting-Register-Trigger
header to complete the registration of an attribution source or trigger, respectively.
See the Attribution Reporting API for more details.
