The optional sector_identifier_uri must be a URL using the https scheme that references a file (see example below) with a single JSON array of Redirect URLs and/or Notification URIs.

[  
   "https://sp.example.com/redirect_uri1",
   "https://sp.example.com/redirect_uri2",
   "https://sp.example.com/notification_uri1",
   "https://sp.example.com/notification_uri2",
   "https://sp.example.com/jwks_uri1",
   "https://sp.other_company.com/jwks_uri2"
]

The Sector Identifier URI provides:

  • a way for a group of services under common administrative control to have consistent PCR values independent of the individual domain names.
  • a way for Service Providers to change service domains without having to re-register all their users and register new values with operators.

The Sector Identifier URI value is only needed when using Mobile Connect DI v2.3 and above and Mobile Connect SI v1.0 and above. It also requires operator implementation, so your operator will let you know if this functionality in implemented and you should provide this value.
