NEF 136 may then receive from NSMF 150 one or more messages which indicate a response to the request for creating the NSI in previous step 624 (step 632 of FIG. 6B). The one or more messages may include the NSSAI configuration data and the NSI ID associated with the NSI and associated NFs. NEF 136 may send to enterprise server 528 one or more messages which indicate a response to the request for communication service of previous step 621 (step 634 of FIG. 6B). The response may include the NSI ID of the NSI representing the private network slice and other relevant information. In turn, enterprise server 528 may receive the response which includes the NSI ID of the NSI representing the private network slice and other relevant information. Enterprise server 528 may associate the NSI ID and other relevant information with the OAuthClientID and Secret, and use the associated information as described above in relation to FIG. 6A (see e.g. steps 610, 612, 614, 616, and 618 of FIG. 6A).
