Course Overview: APIs in Telecom
This course provides a comprehensive introduction to the use of APIs in the telecom sector, covering essential principles, protocols, and real-world applications. Participants will explore how APIs enable automation, scalability, and innovation in telecom services, from billing and network management to 5G and IoT integrations. A special attention is given to three initiatives: TMForums Open APIs, GSMA’s Open Gateway and CAMARA. With hands-on labs and case studies, learners will gain practical skills in API development, security, and management, tailored to the unique demands of telecom networks. This course is ideal for professionals aiming to enhance their expertise in API-driven telecom solutions..
Who Should Attend?
This course is suitable for anyone in telecom looking to leverage APIs for automation, interoperability, and scalability.
Key Questions from Our Latest Virtual Classroom
✔ How do we handle authentication and authorization when implementing Open APIs like those in CAMARA?
✔ How do we ensure user privacy and consent with CAMARA APIs? (e.g., obtaining user consent for location tracking in the “Device Location” API—both live and historical data)
✔ How do CAMARA APIs align with 3GPP specifications, particularly for the 5G standard?
✔ How do CAMARA APIs integrate with existing legacy custom APIs in telecom networks?
✔ What does a CAMARA API implementation look like from an architectural perspective
✔ How can I containerize a CAMARA API and deploy it in a Kubernetes cluster?
✔ What are the best practices for testing a CAMARA API?
This course provides in-depth insights and practical knowledge to help professionals navigate the evolving telecom API landscape effectively.

Prerequisites
This course is accessible to beginners with some IT background but will be most beneficial for those with prior exposure to telecom or software development fundamentals.
Basic Understanding of Telecom Concepts: Familiarity with telecom services and terms, such as network management, provisioning, and CRM, is helpful but not mandatory.
Foundational Knowledge of APIs: Basic understanding of what APIs are, including common types like REST and SOAP, and how they generally function.
Technical Background in IT or Software Development: Experience with programming concepts, especially with HTTP requests and JSON, will help learners get the most out of hands-on labs and coding examples.
Awareness of Networking and Security Principles: Basic knowledge of networking (e.g., IP, DNS) and security practices, including authentication methods (OAuth, API keys), will be beneficial for sections on telecom API security.
