Capture an anonymous scan
Beacon called by the hosted page after a resolve-driven anonymous visit (?_r= linkback present) to record it into the visitor’s own scan history. No-op for an authenticated caller (already captured resolver-side) or a scan_token that doesn’t resolve to a real ScanEvent.
Body
Request body for the anonymous scan-capture beacon.
The resolver's ?_r= linkback token (a ScanEvent id) carried on the hosted-page URL for a resolve-driven visit. Read from window.location.search client-side.
Response
OK
Result of an anonymous scan-capture attempt.
Whether a scan-history row was written or refreshed. False for an authenticated caller (already captured resolver-side), an empty/unresolvable scan_token, or a token that doesn't match any ScanEvent — never an error in any of those cases.
