Unlocking the power of connectivity: How Deutsche Telekom is shaping customer experiences with network APIs

Staying relevant today means more than just adopting the latest technologies—it means placing customer experience at the forefront. Noel Wirzius, Product Manager for Network APIs at Deutsche Telekom, understands this well. Their focus is on building innovative solutions around network APIs, orchestrating the roadmap, and leading key initiatives such as CAMARA and Open Gateway.

Meeting modern customer expectations

As Wirzius notes, customer expectations have evolved significantly in recent years. The digital age has heightened demand for seamless experiences, fast connectivity, and secure communications. Telcos must keep pace, not just by enhancing network speeds, but by redefining how their networks interact with customer needs.

By integrating solutions such as the Number Verification API, DT streamlines user authentication processes, eliminating cumbersome OTP SMS and improving security. Instead of requiring users to manually enter verification codes, the API enables silent, automatic authentication tied directly to the mobile network.

This not only reduces friction during onboarding and login but also minimizes the risk of phishing and SIM swap fraud. As Wirzius puts it, “It’s more secure, and ultimately provides a much better user experience.”

Practical solutions with real-world impact

The Open Gateway Initiative, in which Deutsche Telekom is a leading participant, demonstrates how telcos can turn network capabilities into scalable, developer-friendly services. By adopting standardized APIs defined by the CAMARA project and GSMA, operators make it easier for enterprises to integrate telco functionality into their applications, unlocking new use cases and business models.

Deutsche Telekom’s implementation of Open Gateway APIs is a strong example of how telcos can lead with both technical execution and ecosystem collaboration. By working closely with other operators through initiatives like Local Champions, and partnering with aggregators like Infobip, DT demonstrates how to operationalize Open Gateway in a way that brings tangible value to developers and businesses.

Strengthening trust through security

Security and trust remain paramount. Wirzius highlights DT’s role in combating fraud and enhancing customer security through network insights. APIs can provide vital data to banks and businesses, alerting them to potential SIM swaps or unauthorized activities, significantly reducing customer vulnerability to fraud.

Monetizing and standardizing API innovations

For DT, APIs represent not just technological innovation, but a significant opportunity for monetization. By offering trusted, high-quality data, telcos can create new revenue streams while providing invaluable services to businesses and consumers.

In Germany, collaboration among major operators—Vodafone, Telefonica, and 1&1—under the Local Champions initiative further drives the adoption and standardization of network APIs, ensuring broad accessibility and uniform quality.

Why Deutsche Telekom chose Infobip

To realize the full potential of network APIs, DT strategically partnered with Infobip. The collaboration draws on Infobip’s global CPaaS infrastructure, broad developer access, and experience in building communication tools powered by APIs. It enables DT to deliver telecom capabilities as accessible and scalable services.

Infobip plays an essential role in connecting telecom operators with the developer ecosystem. While DT provides the underlying network intelligence and secure, high-quality data, Infobip ensures that these APIs are delivered in a developer-friendly format, with unified access, consistent documentation, and straightforward integration across multiple operator networks.

By aggregating APIs from different telcos, Infobip allows DT’s services to be embedded into real-world applications across various industries, without the need for custom development. This model speeds up adoption, simplifies delivery, and supports commercial scalability.

This partnership shows what is possible when strong telecom infrastructure is combined with effective developer delivery, helping businesses unlock the value of network APIs more easily.

The future is connected

Deutsche Telekom continues to lead the industry by turning core network capabilities into real business value. With a strong focus on AI powered Quality on Demand and predictive analytics, the company is helping redefine what telcos can offer in a digital world. These advancements are not abstract concepts—they are being developed and deployed to solve real challenges for customers and enterprises.

As one of the most committed operators in the Open Gateway initiative, DT is setting the pace for the entire sector. Its work with standardized network APIs is proving that telecom infrastructure can evolve into a flexible service layer, ready for integration, monetization, and global scale.

By partnering with Infobip, DT ensures these innovations reach the developer ecosystem in a usable, enterprise ready format. Together, they are building a future where telecom services are intelligent, secure, and seamlessly embedded into everyday digital experiences.
