OpenCAPIF SDK brings a set of functions to integrate with the 5G Core's function CAPIF, as defined in [3GPP Technical Specification (TS) 29.222 V18.5.0 Common API Framework for 3GPP Northbound APIs](https://www.etsi.org/deliver/etsi_ts/129200_129299/129222/18.05.00_60/ts_129222v180500p.pdf). This section shows the mapping between the Python functions available in this SDK and the CAPIF OpenAPI APIs defined the reference standard:

NOTE: Above mentioned CAPIF APIs are defined in these 3GPP references:

OpenCAPIF SDK implements this set of features to easily integrate an application with CAPIF NF either manually or integrating SDK library directly within app code.

Before usage it's needed to have completed the [prerequirements](./sdk-prerequirements.md) section, the [installation](./sdk-installation.md) section and the selected parts of the [configuration](./sdk-configuration.md) section.

Before using it, it is required to have fullfiled the [prerequirements](./sdk-prerequirements.md) section, the [installation](./sdk-installation.md) section and the selected parts of the [configuration](./sdk-configuration.md) depending on the CAPIF role the NetApp is going to play.
