Open Digital Architecture

Introduction to Open APIs

TM Forum’s Open API program is a global initiative to enable seamless connectivity, interoperability and portability across complex ecosystem services

Leading the industry in Open API standards

As of February 2025, TM Forum's Open APIs have been downloaded over 1 Million times. TM Forum's Open API project has been at the forefront of the challenge to find the right mechanism for CSPs and vendors to work together in a faster and more flexible way. A new generation of APIs are now required to drive future growth, speeding up the ‘time to deliver value’ and accelerating the deployment of new services and products by enabling plug-and-play software integration that will revolutionize the software lifecycle for telecoms.

NEW TM Forum’s Gen5 Open APIs for a future proof ecosystem

TM Forum has launched its Gen5 Open APIs to address these needs. These “5th generation APIs” will support the latest event-driven architectures, provide a simpler experience for developers, and enable the intent-based automation which is essential to the efficient operation and management of telecoms IT and networks.

These Gen5 Open APIs create a pathway to simplified APIs for use in industry specific applications such as WLAN, 5G slicing etc. TM Forum is partnering with other standards development organizations such as GSMA Open Gateway / CAMARA to ensure standardization and interoperability across the industry.
