Calendar API与Reports API返回的Meet会议ID不一致及考勤查询咨询

Great question—this is a common point of confusion when working with Google's Calendar and Reports APIs together. Let’s break down why the IDs differ and how to bridge them for attendance tracking.

First off, those two IDs serve completely different purposes:

• The conferenceId returned by Calendar API is the public Meet meeting code (the hyphenated 12-character string like xxx-xxxx-xxx). This is the user-friendly code you share with people to join the meeting—it’s designed for readability and easy sharing.
• The conference_id from Reports API is an internal unique instance ID. It’s a longer, opaque string Google uses behind the scenes to track the specific meeting instance, including every join, leave, and activity tied to it. These IDs aren’t meant for end-users, so they don’t follow a human-readable format.

To connect your Calendar-created meeting to its attendance logs in Reports API, here’s what you need to do:

1. Save the public meeting code: When you create the meeting via Events.insert, make sure to store the conferenceData.conferenceId value (that xxx-xxxx-xxx string).
2. Filter Reports API by meeting code: When calling the activities.list endpoint (set applicationName=meet), use the filters parameter to match the meeting_code to your Calendar conference ID. Example filter string:

   filters=meeting_code==your-meeting-code-here
   

3. Pull attendance details: The filtered results will include all join and leave events for the meeting. Look for entries where eventName is join_call or leave_call—the actor.email field will tell you which participant took that action.

If you need even tighter alignment, you can also cross-reference the Calendar event’s id or iCalUID with the parameters.calendar_event_id field in Reports API records. This works because the meeting is directly linked to the Calendar event you created.
