Stadsnätsportalen's implementation of the ON-API. For some reasons the implementation differ from other single-CO/single-SP implementations. The base url needs to be modified for each origin you wish to fetch data from.

If you are a service provider (SP) you access the API using a specific coId as origin. Available coId endpoint URLs can be seen in the Stadsnätsportalen dashboard when logged in as a SP

All coId codes can also be found here where they can also be read by machine. SP can only access coId's where you deliver services through the Tjänsteguide
