 Args:
   resourceName: string, Required. The resource name to return connections for. Only `people/me` is valid. (required)
   pageSize: integer, Optional. The number of connections to include in the response. Valid values are between 1 and 1000, inclusive. Defaults to 100 if not set or set to 0.
-  pageToken: string, Optional. A page token, received from a previous `ListConnections` call. Provide this to retrieve the subsequent page. When paginating, all other parameters provided to `ListConnections` must match the call that provided the page token.
+  pageToken: string, Optional. A page token, received from a previous response `next_page_token`. Provide this to retrieve the subsequent page. When paginating, all other parameters provided to `people.connections.list` must match the first call that provided the page token.
   personFields: string, Required. A field mask to restrict which fields on each person are returned. Multiple fields can be specified by separating them with commas. Valid values are: * addresses * ageRanges * biographies * birthdays * calendarUrls * clientData * coverPhotos * emailAddresses * events * externalIds * genders * imClients * interests * locales * locations * memberships * metadata * miscKeywords * names * nicknames * occupations * organizations * phoneNumbers * photos * relations * sipAddresses * skills * urls * userDefined
   requestMask_includeField: string, Required. Comma-separated list of person fields to be included in the response. Each path should start with `person.`: for example, `person.names` or `person.photos`.
-  requestSyncToken: boolean, Optional. Whether the response should include `next_sync_token` on the last page, which can be used to get all changes since the last request. For subsequent sync requests use the `sync_token` param instead. Initial full sync requests that specify `request_sync_token` and do not specify `sync_token` have an additional rate limit per user. Each client should generally only be doing a full sync once every few days per user and so should not hit this limit.
+  requestSyncToken: boolean, Optional. Whether the response should return `next_sync_token` on the last page of results. It can be used to get incremental changes since the last request by setting it on the request `sync_token`. More details about sync behavior at `people.connections.list`.
   sortOrder: string, Optional. The order in which the connections should be sorted. Defaults to `LAST_MODIFIED_ASCENDING`.
     Allowed values
       LAST_MODIFIED_ASCENDING - Sort people by when they were changed; older entries first.

-  syncToken: string, Optional. A sync token, received from a previous `ListConnections` call. Provide this to retrieve only the resources changed since the last request. When the `syncToken` is specified, resources deleted since the last sync will be returned as a person with [`PersonMetadata.deleted`](/people/api/rest/v1/people#Person.PersonMetadata.FIELDS.deleted) set to true.
