About offline-event data
You can import offline events from sources that don't have an internet connection or that otherwise cannot support real-time event collection via the SDKs or Measurement Protocol. Once you upload events, they are processed as though they were collected via our SDKs, and use the timestamp you provide or the timestamp of the upload if you don't provide your own.
You can import any event that matches the ones Analytics collects automatically or the ones we recommend for different verticals, or any custom event, parameter, or user property that is properly formed. Learn more
Removing this data requires either a data-deletion request or user deletion.
How offline-event-data import works
To import offline events you create a CSV file that matches the Analytics event schema. See the template examples below.
Create the custom dimensions
If you're importing values for dimensions that don't already exist in Analytics and you want to see that data in reports, then you need to create those dimensions before you upload your data. Learn more
Once you create the custom dimensions, Analytics needs up to 4 hours before it’s ready to recognize the data you import. (You can verify that the custom dimensions are processed by opening an exploration and checking to see if the dimensions are available in the dimension picker.)
Create a CSV file
Create a CSV file of your event data using the template below as a guide.
Upload data
The general upload procedure is outlined in About Data Import.
When you create the data source, select Offline event data.
For offline events, your imported fields get mapped to Analytics fields automatically.
After you upload your data, it can take up to 24 hours for Analytics to make that data available in reports, audiences, and explorations.
Deleting a data source from the data-upload service does not delete uploaded data. If necessary, and as with all other collection methodologies, you may need to follow up with a data deletion request to remove data uploaded via Data Import.
