Unlocking Programmable Networks: The Convergence of CPaaS and Cloud-Native Cores

Communications Platform as a Service (CPaaS) and cloud-native telco cores are converging to transform networks into programmable platforms, enabling communications service providers (CSPs) to expose “connectivity-as-code” and monetize 5G capabilities through standardized application programming interfaces (APIs).

• CPaaS is a cloud-based delivery model that allows developers to integrate real-time communication tools, such as voice, video and messaging into applications via APIs.
• Connectivity-as-code refers to the ability for developers to programmatically trigger and control specific network behaviors, such as latency or bandwidth, directly from within their software.
• A cloud-native telco core is a mobile network architecture built using microservices and containers. This architecture is designed to run on cloud infrastructure to provide maximum scalability, automation and flexibility.

Traditional CPaaS platforms abstracted carrier-based SMS, voice, video and IP-based messaging (such as Facebook Messenger, Telegram, Signal, WhatsApp or RCS) into simple APIs that developers could embed in apps within minutes. 5G network APIs extend this model deeper into the network, exposing capabilities such as quality-on-demand, slicing, location, device status and network insights. For developers, the result is a continuum: CPaaS handles the communication layer, while network APIs program how connectivity behaves per session, user or device.

This shift is enabled by industry initiatives such as GSMA Open Gateway and CAMARA, which define universal APIs to access operator networks in a consistent way across markets. Rather than having to create custom integrations with each CSP, developers can rely on harmonized API behavior for identity, quality of service (QoS) and other network functions. This greatly reduces the friction involved in building on telco assets.

Cloud-Native 5G Cores are the Foundation for Agility

A cloud-native 5G Core built on microservices and containers is the technical foundation that makes network programmability and rapid API innovation possible. Vendors and CSPs are deploying fully virtualized and containerized cores that run on Kubernetes-based platforms across private, public and hybrid clouds. These architectures allow network functions to be scaled horizontally, updated continuously, and placed flexibly, from central clouds to the edge, based on workload and latency needs.

CSPs using a multicloud 5G core realize accelerated time-to-market for new services, enhanced resilience during periods of high traffic or disasters, and improved efficiency through off-the-shelf cloud infrastructure. This agility is essential, because monetizing network APIs requires continuous experimentation, including rapid onboarding of new capabilities, A/B testing of pricing models and frequent enhancements to developer-facing services.

Connectivity-as-Code and CPaaS in Practice

When CPaaS capabilities are integrated with a cloud-native 5G core, CSPs can offer “connectivity-as-code” by fusing communication functions with real-time control of network behavior. In this model, a single API call from an enterprise application can set up a communication session and request a specific connectivity profile (for instance, guaranteed bandwidth, low latency or enhanced security) for the duration of that interaction.

Some representative use cases include:

• Authenticated identity: Network-based number verification, SIM-based identity and one-time password flows reduce fraud for login, account recovery and Know Your Customer (KYC) requirements.
• Secure payments: Telco-based ID and device intelligence enhance fraud checks for digital payments and in-app purchases, complementing bank and card data.
• Precision tracking: Network location APIs support asset tracking, smart logistics and geofencing, using carrier-grade data rather than just device GPS.
• QoS for critical sessions: Quality-on-demand APIs guarantee that premium video, industrial control or telemedicine sessions receive the performance they require, on demand.

In each scenario, the CPaaS layer orchestrates communications, whether it is voice, messaging or video. The 5G core enforces per-session policies via exposed network APIs, creating differentiated experiences that customers will pay for.

Monetizing Network APIs

CSPs are shifting their business model from offering “best-effort connectivity” to providing network APIs as monetizable services. The following emerging monetization models are of particular interest:

• Developer subscription: Developers pay a recurring fee to access a bundle of APIs, such as identity, QoS or location, with defined quotas and service level agreements (SLAs).
• Pay-per-use transactions: Each API call, such as a number verification or QoS boost, is billed per transaction, often with tiered pricing.
• Revenue sharing: CPaaS and digital platforms share revenue with CSPs for services powered by network APIs, such as fraud prevention or premium connectivity.
• Bundled offers: Network APIs are embedded into higher-level solutions, such as CPaaS fraud suites or IoT platforms, with aggregated pricing per user, device or app.

To support these models at scale, CSPs rely on API management platforms to meter, secure and charge for individual API calls, turning network features into measurable revenue streams. Performance-based offerings where customers pay for defined levels of latency, throughput or reliability rather than simple data volume, are particularly promising for enterprise and B2B2C use cases.

Converged Interconnect and Settlement for Global Coverage

As more CPaaS providers, hyperscalers and independent developers consume network APIs from multiple operators, financial flows become complex and global. An enterprise solution may call APIs from multiple CSPs across regions via an aggregator, mixing communication and network APIs from different layers of the value chain. In the absence of a converged interconnect and settlement system, the tracking of usage, the enforcement of SLAs and the reconciliation of revenue across parties becomes a challenging task that is difficult to manage effectively.

Industry bodies are addressing this by defining common frameworks and certification schemes that unify the behavior of CAMARA and TM Forum APIs under the GSMA Open Gateway umbrella. This helps CSPs standardize commercial products and settlement processes across networks, paving the way for a global API marketplace where capabilities can be combined and monetized consistently.

To achieve this, these organizations focus on three critical areas:

• CAMARA: Works on defining the actual northbound APIs to ensure they are developer-friendly and consistent across all operators, regardless of the underlying vendor equipment.
• GSMA Open Gateway: Provides the strategic and commercial framework that aligns dozens of mobile operator groups worldwide, ensuring that an API written for one network works on another.
• TM Forum: Offers the operational standards and Open APIs necessary for back-end orchestration, allowing CSPs to automate the complex billing and lifecycle management of these digital services.

Security, Ecosystems and Edge

A successful network strategy addresses critical business concerns, including security and compliance, ecosystem collaboration and edge computing. These three pillars represent the connective tissue that transforms raw 5G capabilities into enterprise-grade solutions. Security ensures that sensitive subscriber data remains protected while exposed via APIs. Ecosystems provide the diverse developer base needed for scale. The edge provides the physical proximity required for the high-performance applications 5G promised.

• Security and compliance by design: Network APIs must implement privacy-by-default, consent management and strong authentication, especially for identity and location services, to comply with regulations and maintain trust.
• Ecosystem orchestration: It is not feasible for a single provider to develop the full stack independently. Collaboration among CSPs, vendors, hyperscalers and vertical specialists on open ecosystems is essential for expanding network API usage.
• Edge and network exposure: The deployment of cloud-native cores in edge and hybrid clouds facilitates the utilization of low-latency capabilities in proximity to the user or device. This capability enables the delivery of immersive media, industrial automation and mission-critical IoT applications.

By integrating these elements, CSPs can ensure that the programmable network is a secure, scalable and high-performance business environment.

Seizing the Programmable Opportunity is a Strategic Mandate for CSPs

The market for network APIs is developing quickly, with global initiatives, reference implementations and early commercial offers already in place. Hyperscalers, CPaaS providers and digital-native platforms are rapidly gaining traction with developers, positioning themselves as the preferred access points to programmable connectivity. CSPs that adopt programmable networks can avoid becoming mere commodity transport providers, enabling others to capture the application, data and service layers above them.

To seize this opportunity, it is essential to invest in cloud-native 5G cores, standardize on Open Gateway/CAMARA APIs, build converged interconnect and settlement capabilities and collaborate with CPaaS ecosystems to launch compelling “connectivity-as-code” offers. For telcos with the ambition to become techcos, the time to transform their networks into programmable revenue engines is now.
