The WIPO Digital Access Service Office Portal ("DAS Office Portal"(“DAS”), available at DAS Office Portal, allows https://www.wipo.int/das/en/, allows you to meet requirements for providing priority and similar documents in respect of participating Offices, without the need to obtain and send multiple certified paper copies of an application.
Instead, you ask the Office where you are claiming priority (“Office of Second Filing” or OSF) to download a copy of the document directly from a digital library, normally held by or on behalf of the Office where the earlier application was filed from which priority is claimed (“Office of First Filing” or OFF).
...
It is essential that users properly understand what is required to give permission for this transfer. Because the system is designed to work between pairs of Offices, which may have no other working relationship, there are steps involved, which are different from, or additional to those in other priority document exchange systems in operation between certain Offices.
