        The `calendar` query parameter identifies one calendar as `,`, e.g. `calendar=135,alice@example.com`. Both values are returned for each connected calendar by `GET /v2/calendars`. To load busy times from multiple calendars, pass the `calendar` query parameter multiple times, e.g. `calendar=135,alice@example.com&calendar=200,bob@example.com`. Only the first comma separates the two values, so an `externalId` containing commas is kept intact.
