Workspace member invite
Follow the emailed link, read the organisation name, and continue to sign up with the invited email when required. After authentication you inherit the scopes printed on the invite—either specific websites or the full workspace.
Measurement delegation invite
A measurement-only flow asks the recipient to authorise read-only Search Console and Analytics access via Google OAuth for the inviting organisation—no Blooms workspace membership implied.
Tips
Open invites in the same browser you intend to use for OAuth to avoid losing state.
