Auth	Login required

Path parameters

Meet log ID.

Request body

memostring | nulloptional

Memo (up to 500 characters). Empty or null clears it.

eventIdstring | nulloptional

The event where you met; null clears it. Returns 400 (errorCode 40212) if it is not a candidate.

Notes

A community's log (one with ownerCommunityId) can be handled by any current admin of that community, even one who did not handle the exchange. Someone who is no longer an admin gets 404 (errorCode 40210), even for logs they handled.

A memo on a community's log is visible to all admins of that community (a memo on a personal log is visible only to you).

Response

Returns MeetLog.
