Method: otherContacts.list

List all "Other contacts", that is contacts that are not in a contact group. "Other contacts" are typically auto created contacts from interactions.

Sync tokens expire 7 days after the full sync. A request with an expired sync token will get an error with an google.rpc.ErrorInfo with reason "EXPIRED_SYNC_TOKEN". In the case of such an error clients should make a full sync request without a syncToken.

The first page of a full sync request has an additional quota. If the quota is exceeded, a 429 error will be returned. This quota is fixed and can not be increased.

When the syncToken is specified, resources deleted since the last sync will be returned as a person with PersonMetadata.deleted set to true.

When the pageToken or syncToken is specified, all other request parameters must match the first call.

Writes may have a propagation delay of several minutes for sync requests. Incremental syncs are not intended for read-after-write use cases.

See example usage at List the user's other contacts that have changed.
