In order to apply for a GLN, the service provider should execute a Provision GLN request. The header contains the Forward-Sender of the service provider itself, i.e. the GLN of the requestee. Additionally, the header contains the Forward-ID, i.e. the unique ID of the receiver (the broker in this case) which will always be: urn:scsn:ids:agents:broker-extension. Additionally, the request-body contains the PartyLegalEntityID, i.e. GLN, of the organization to be connected and its tax number, i.e. PartyTaxID, for referring purposes. Note that it is optional to provide the PartyLegalEntityID and this should only be used when an organization wants to use its own GLN! If the field is empty, the SCSN Foundation will provide a GLN.
