CAMARA, the Global Telco API Alliance, Unveils its Spring25 Meta-Release: Cutting- Edge APIs for Seamless Network Functions Access

• 38 mature and stable APIs enter the open Telco ecosystem with second major CAMARA release, with 30+ more in development

• New CAMARA APIs bring added security and interoperability profiles, while updates to existing APIS include enhanced notifications, events, and error response functionality

• CAMARA community onsite in London at Open Networking & Edge Summit and KubeCon + CloudNativeCon, March 31-April 4 in London

LONDON— Open Networking & Edge Summit— March 31, 2025, The Linux Foundation’s CAMARA project, an open source community addressing telco industry API interoperability, today announced the availability of its second official release, CAMARA “Meta-release Spring25”. The meta-release contains 13 new and 23 updated APIs, 36 APIs in total, that have been vetted for quality, consistency, and stability through rigorous release management processes. 

Initiated in 2021 by a small number of telco operators, vendors and hyperscalers, CAMARA officially launched in February 2022 with 22 initial partners and graduated to a funded model in September 2023, with 250 participating organizations and over 750 contributors. Since then, the project has grown to: 1250+ contributors among 427 organizations, with 11 API sub projects, 21 sandbox projects, 60 APIs, and five working groups. This growth rate indicates strong ecosystem support in enabling more accessible and standardized open telco APIs. 

"The Spring25 Meta-Release marks a significant milestone in CAMARA’s mission to drive open, standardized APIs for the global telecom industry," said Arpit Joshipura, general manager, Networking, Edge and IoT at the Linux Foundation. "We’re continuing to see broad ecosystem support for CAMARA and its innovative APIs that empower developers, accelerate service innovation, and strengthen the ecosystem of open collaboration that is vital for the future of connectivity."

“This milestone is testament to CAMARA’s ongoing commitment to open network innovation,” said Nathan Rader, CAMARA Governing Board Chair and VP, Service and Capability Exposure, Deutsche Telekom. “The availability of even more mature, stable telco APIs expands the possibilities for developers and organizations to harness this work more effectively, driving new opportunities across the ecosystem. We look forward to seeing how the industry leverages these enhancements to deliver next-generation services and experiences."

With the meta-release Spring25, CAMARA now has 38 mature APIs within the ecosystem, adding 13 new since the Fall24 meta-release. The APIs included in the release represent a consistent set of aligned, quality APIs that have met rigorous release management and design guidelines. APIs included in the release represent a foundation for CAMARA APIs moving forward (both this in development and those in production). The community is committed to delivering twice-yearly updates to vetted APIs so network operators can plan deployments within their networks. Additionally, API users can be confident in getting the latest and most stable versions from their network operators and API providers.

The meta-release Spring25 includes updated CAMARA design guidelines with significant improvements within the area of notifications, events, and error responses. These changes have been applied by all APIs in the meta-release. The Security and Interoperability Profile has been revised, offering more clarity and more options for API providers to ensure  the secure, privacy-friendly and seamless access for developers to network information and capabilities.

APIs included in the Meta release:

• Stable CAMARA APIs: Device Reachability Status, Device Roaming Status, Location Verification, Number Verification, One-time Password SMS, QoS Profiles, Quality On Demand, and SIM Swap
• Updated Versions of existing CAMARA APIs: Applications Profiles, Call Forwarding Signal, Carrier Billing, Carrier Billing Refund, Connectivity Insights, KYC Fill-In, KYC Match, Location Retrieval, Population Density Data, QoD Provisioning,  and the updated versions of APIs to subscribe for event notifications: Connectivity Insights Subscriptions, Device Reachability Status Subscriptions, Device Roaming Status Subscriptions, Geofencing Subscriptions, SIM Swap Subscriptions
• Initial versions of new CAMARA APIs, ready to be implemented by network operators: Blockchain Public Address, Connected Network Type (including Subscriptions), Customer Insights, Device Identifier, Device Swap, Know Your Customer Age Verification, Know Your Customer Tenure, Number Recycling, Region Device Count, WebRTC Call Handling, WebRTC Events and WebRTC Registration

Additional release details:

• The 38 APIs included in the meta-release are organized into 19 different API repositories 
  • Nine of which were recently promoted by the Technical Steering Committee (TSC) to the “Incubated” stage: Call Forwarding Signal, Device Location, Device Status, Simple Edge Discovery, Number Verification, OTP Validation, Sim Swap, Know YourCustomer, Quality On Demand
• Beyond the 10 Sandbox repositories which participated in the meta-release, there are 24 more Sandbox API repositories; this is where work on the next wave of CAMARA APIs is happening!

CAMARA offers new opportunities for collaboration between network operators, marketplaces, aggregators and API customers. CAMARA is pleased to be selected as the Network API specification location for Aduna amongst leading global telecoms. A critical success factor is also the established alignment with GSMA Open Gateway and TMForum about forming  an open, global, accessible API ecosystem. The benefit for customers and developers comes in the form of consistent and user-friendly access to network capabilities, thus enabling developers to seamlessly deploy applications to run consistently across telco networks and countries. This prevents fragmentation and empowers faster, more versatile advancement of global application portability and broad industry adoption of new features and capabilities. 

In addition to its broad portfolio of participating organizations, the CAMARA fund is composed of 10 Premium sponsors (including Accenture, Deutsche Telekom, Ericsson, Microsoft, Nokia, Orange,  Telefonica, Verizon, Vodafone, T-Mobile), 8 General sponsors (including AlphaZero, CableLabs, Centillion, Charter Communications, INDY Kite, INVIA, Scenera, Shabodi), and one Associate sponsor (OpenID Foundation).

Meet CAMARA at KubeCon + CloudNativeCon EU 

The CAMARA community will host a booth onsite at KubeCon + CloudNativeCon EU, April 1-4, where attendees can learn more about the community and how to get involved in the open telco API ecosystem. Developers, service providers, vendors, hyperscalers , aggregators, and enterprises are encouraged to stop by and learn more about the benefits of open APIs. 

CAMARA project invites all interested parties to help build the best APIs for all telecom customers by joining as a Premium sponsor, General sponsor, associating organization, participating organization, or individual. More details on the project, as well as how to join, are available at https://camaraproject.org/.
