Keep the following best practices in mind:\n\n1. The `timestamp_micros` of events and user properties defaults to the request\n time. When sending an event or user property change that occurred in the\n past, override the timestamp as described in the [sending events](/analytics/devguides/collection/protocol/ga4/sending-events) guide and\n the [user properties](/analytics/devguides/collection/protocol/ga4/user-properties) guide.\n\n2. For accurate Realtime reports and engagement metrics, include the\n `engagement_time_msec` event parameter set to the milliseconds elapsed since\n the preceding event.\n\n| Use case | Session ID | Request time requirement | `timestamp_micros` requirement |\n|------------------------------------------------------|--------------|-----------------------------------------------------------------------------------------|---------------------------------------------------------------|\n| Assign User-ID to events | Required | \\\u003c= end of the session start's business day | \\\u003e= session start and \\\u003c= session end |\n| Session attribution | Required | \\\u003c= session start + 24 hours | \\\u003e= session start and \\\u003c= session end |\n| Export events to advertising platforms | Not required | \\\u003c= last session business day + 63 days | \\\u003e= request time minus two business days and \\\u003c= request time |\n| Send events or user properties for audience creation | Not required | Web: \\\u003c= latest online event time + 30 days App: \\\u003c= latest online event time + 42 days | \\\u003e= request time minus two business days and \\\u003c= request time |\n\nAssign User-ID to events\n------------------------\n\nUse the Measurement Protocol to provide online or offline events with a\n[User-ID](//support.google.com/analytics/answer/9213390).\n\nHere are some example use cases for adding a User-ID to an event:\n\n1. Your online measurement lacks the information needed to look up the\n User-ID for online events, but you have an event-processing pipeline that\n is able to make the association between an online session and a User-ID.\n\n In this scenario, you are using the Measurement Protocol to provide\n *online* events with a User-ID.\n2. You don't have the User-ID for events you are sending with the\n Measurement Protocol, but you want those events to be associated with a\n User-ID if the user logged in online over the course of the session.\n\n In this scenario, you are using online events to provide\n *Measurement Protocol* events with a User-ID.\n\nHere are the requirements to add a User-ID to an event:\n\n- Include the `session_id` in the event's parameter list.\n- Send the Measurement Protocol events on the *same business day* as the online session.\n- If you override `timestamp_micros`, set it to a timestamp between the start and end time of the online session.\n- If your goal is to provide User-ID for online events, set the `user_id` in the request.\n- If your goal is for each Measurement Protocol event to have the User-ID from its corresponding online session, you don't need to set `user_id`.\n\nSession attribution\n-------------------\n\nMeasurement Protocol events that meet specific requirements appear in reports\nwith the same session attributes (such as geographic information, source,\nmedium, and campaign) as online events from the same session.\n\nHere are the requirements for session attribution:\n\n- Include the `session_id` in the event's parameter list.\n- Send the request no later than 24 hours after the start of the online\n session.\n\n For example, if the session started at 11:15 AM on Monday in your property's\n time zone, send the request before 11:15 AM on Tuesday.\n- If you override `timestamp_micros`, set it to a timestamp between the\n start and end time of the online session.\n\nExport events to advertising platforms\n--------------------------------------\n\nGoogle Analytics includes the events you send using Measurement Protocol\nin exports to linked advertising products such as Google Ads or Campaign Manager\n360.\n| **Tip:** This use case doesn't require `session_id`.\n\nA few common scenarios where this is useful include:\n\n- Your business has offline events that you want included in advertising attribution and reporting.\n- You have additional events in a system that is not available to tagging or the Firebase SDK, but you still want to include those events in linked products.\n\nHere are the requirements to export events to advertising platforms:\n\n- Send the request no later than the end of the business day 63 days after\n the latest online event, even if the key event's attribution window is more\n than 63 days.\n\n For example, if the latest online event for the `client_id` or\n `app_instance_id` occurred on March 1, send the Measurement Protocol\n event no later than the end of the business day on May 3.\n- If you override `timestamp_micros`, set it to a timestamp within the last\n three business days.\n\nSend events or user properties for audience creation\n----------------------------------------------------\n\nEvents and user properties sent using Measurement Protocol are included in\nthe evaluation of [audience conditions](//support.google.com/analytics/answer/9267572) if you adhere to a few requirements.\n| **Tip:** This use case doesn't require `session_id`.\n\nHere are the requirements to send events or user properties for audience\ncreation:\n\n- Send the request to a Web stream no later than the end of the business day\n 30 days after the latest online event for the same `client_id`.\n\n For example, if the latest online event for the `client_id` occurred on\n March 1, send the Measurement Protocol event no later than the end of the\n business day on March 31.\n- Send the request to an App stream no later than the end of the business day\n 42 days after the latest online event for the same `app_instance_id`.\n\n For example, if the latest online event for the `app_instance_id` occurred\n on March 1, send the Measurement Protocol event no later than the end of\n the business day on April 12.\n- If you override `timestamp_micros`, set it to a timestamp within the last 3\n business days."]]
