In some cases, you might need to mask the IP addresses of hits sent to Google Analytics.
For all events
To mask IP addresses for all events, update the config
for your
property by setting the value of the anonymize_ip
parameter to true
:
gtag('config', '<GA_MEASUREMENT_ID>', { 'anonymize_ip': true });
For a single event
To mask the IP address for a single event, set the anonymize_ip
parameter in the parameters object:
gtag('event', 'your_event', { 'anonymize_ip': true });
