NextJS React应用中代表双用户创建Google Calendar活动及Google Meets链接的实现与权限问题问询

Hey there! Let's break down your questions one by one:

Absolutely! You can make this work, but there are a few key prerequisites and details to keep in mind:

• First, you must get authorization from both users. Google's Calendar API requires explicit permission to access a user's calendar data—this is a privacy safeguard, so you can't just create events for someone without their consent.
• When creating the event, add both User A and User B as attendees, and set the event's visibility to private. Then, include the conferenceData field in your API request to generate a Google Meet link automatically. Once the event is created, only the added attendees will have access to the meeting link and event details, which fits your private meeting needs perfectly.

This depends entirely on the OAuth authorization flow you use and how you persist user permissions:

• If your app already had User A go through a frontend OAuth flow, and your backend stored their refresh token, then you can absolutely handle the event creation entirely in the backend. Just use the refresh token to get a valid access token, then call the Calendar API to create the event—no need for User A to re-authorize. This is the most common approach for this kind of feature.
• If you want to skip frontend OAuth entirely and do everything backend-side, you'll need to use a Service Account with Domain-Wide Delegation enabled. But this only works for users in a Google Workspace (formerly G Suite) domain—regular personal Google accounts don't support this. So if all your users are part of the same Workspace domain, you can use the service account to impersonate both User A and B to create the event. For personal accounts though, this isn't an option—you have to get User A's authorization first (either via frontend or a backend-initiated OAuth flow).
• One quick note: When creating the event after User A accepts the request, make sure to set the sendUpdates parameter appropriately (the default usually sends notifications) so both users get an email with the Google Meet link and event details.
