Service Manager is a Go implementation of the CAPIF Core function, which is based on the 3GPP TS "29.222 Common API Framework for 3GPP Northbound APIs (CAPIF)" interfaces, see https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3450.
Generation of API Code
The CAPIF APIs are generated from the OpenAPI specifications provided by 3GPP. The generate.sh script downloads the specifications from 3GPP, fixes them and then generates the APIs. While these files are checked into the repo, they can be re-generated using generate.sh. The specifications are downloaded from the following site; https://www.3gpp.org/ftp/Specs/archive/29_series. To see the APIs in swagger format, see the following link; https://github.com/jdegre/5GC_APIs/tree/Rel-17#common-api-framework-capif.
