2025-06-11
2025-05-28
- Added a validation endpoint
https://region1.google-analytics.com/debug/mp/collect
for events to be collected in the EU.
2025-05-14
- Added
user_location and ip_override fields. Use either field to
send geographic information for Measurement Protocol events.
- Added a new endpoint
https://region1.google-analytics.com/mp/collect to use
if you want your Measurement Protocol data to be collected in the EU.
2024-09-10
- Google Analytics now automatically joins the most recent device information
from tagging with Measurement Protocol events using
client_id or
app_instance_ID.
2023-09-27
2023-01-23
- Google Analytics 4 now automatically joins the most recent geographic
information from tagging with Measurement Protocol events using
client_id or
app_instance_ID.
2022-05-23
session_id: include session_id as a param, so that measurement protocol
events appear in session-based reporting.user_id: previously, if (a) app_instance_id/client_id is sent without
user_id and (b) measurement protocol events are sent with app_instance_id
with user_id, the MP events weren't being exported to Ads properly. This has
been fixed so that now the measurement protocol events are exported and
attributed.
2021-02-26
- Conversion events no longer need to be sent with an 8 hour delay.
2020-10-14
- Updated naming from App + Web to Google Analytics 4.
