Hello,

I am encountering the same issue as detailed in https://issuetracker.google.com/216326913 and would like to provide specific technical details of my attempts to track events with GA4 without using an SDK.

1. Measurement Protocol Attempts: I've been using the Measurement Protocol for server-side tracking. Here are the exact requests I've sent:

• First Event:

POST https://www.google-analytics.com/mp/collect?api_secret=API_SECRET_REDACTED&measurement_id=MEASUREMENT_ID_REDACTED

JSON data:

{"client_id":"1706703316.1706703316","user_id":"278285469","non_personalized_ads":false,"user_properties":{"language_code":{"value":"en"}},"events":[{"name":"request_received","params":{"engagement_time_msec":"100","session_id":1706703316,"chat_type":"private","debug_mode":1}}]}

• Second Event:

POST https://www.google-analytics.com/mp/collect?api_secret=API_SECRET_REDACTED&measurement_id=MEASUREMENT_ID_REDACTED

JSON data:

{"client_id":"1706703316.1706703316","user_id":"278285469","non_personalized_ads":false,"user_properties":{"language_code":{"value":"en"}},"events":[{"name":"message_processed","params":{"session_id":1706703316,"chat_type":"private","card_number_check":"card_number_valid","debug_mode":1}}]}

• Third Event:

POST https://www.google-analytics.com/mp/collect?api_secret=API_SECRET_REDACTED&measurement_id=MEASUREMENT_ID_REDACTED

JSON data:

{"client_id":"1706703316.1706703316","user_id":"278285469","non_personalized_ads":false,"user_properties":{"language_code":{"value":"en"}},"events":[{"name":"card_processed","params":{"session_id":1706703316,"chat_type":"private","card_status":"green","debug_mode":1}}]}

Despite these being correctly sent, they are not visible on GA4's DebugView (/admin/debugview/overview).

Validation Server Response: Sending these events to the GA4 validation server does not yield any validation errors, indicating that the request bodies are correct.

2. Emulating gtag.js: I tried emulating gtag.js for event tracking. This approach worked initially (events appeared in GA4 DebugView), but subsequent events sent soon after did not appear in DebugView. Here are the requests for reference:

• First Emulated Event:

POST https://region1.google-analytics.com/g/collect?v=2&tid=MEASUREMENT_ID_REDACTED&_p=1706703436425234&cid=1706703436.1706703436&uid=278285469&ul=en&_ss=1&sid=1706703436&seg=1&_et=100&en=request_received&ep.chat_type=private&_s=1&_ee=1&_dbg=1

• Second Emulated Event:

POST https://region1.google-analytics.com/g/collect?v=2&tid=MEASUREMENT_ID_REDACTED&_p=1706703436695275&cid=1706703436.1706703436&uid=278285469&ul=en&sid=1706703436&seg=0&en=message_processed&ep.chat_type=private&ep.card_number_check=card_number_valid&_s=1&_ee=1&_dbg=1

• Third Emulated Event:

POST https://region1.google-analytics.com/g/collect?v=2&tid=MEASUREMENT_ID_REDACTED&_p=1706703439226254&cid=1706703436.1706703436&uid=278285469&ul=en&sid=1706703436&seg=0&en=card_processed&ep.chat_type=private&ep.card_status=green&_s=1&_ee=1&_dbg=1

Given these details, I am seeking guidance on how to effectively track events with GA4 without using an SDK. Any insights or solutions regarding this issue would be greatly appreciated.

Thank you for your attention to this matter.
