A network API program does not need to begin with 20 APIs, a new business unit and a year-long transformation project.
A better first target is smaller: pick two or three commercially useful capabilities, expose them in a standard way, put onboarding and charging around them, and get real developers using them.
The market is already moving in this direction. As of March 2026, 86 operator groups representing more than 300 networks and 80% of global mobile connections were aligned with the GSMA Open Gateway framework. More than 60 channel partners were commercializing network APIs.
Here is a practical 90-day route from network capability to a usable API product.
Days 1–15: Pick the first APIs
Do not start by exposing everything your network can technically support.
Start with a business problem.
For fraud and identity, that could mean Number Verification or SIM Swap. For payments, Carrier Billing may be relevant. Other opportunities include location, device information and Quality on Demand.
GSMA’s current Open Gateway catalogue includes APIs across authentication and fraud prevention, location, device information, communication quality, payments and charging.
Choose APIs using three questions:
- Is there a clear enterprise problem?
- Can the underlying network capability be exposed now?
- Is someone prepared to pay for the outcome?
Two APIs with a clear buyer are more useful than ten APIs waiting in a developer portal.
Days 16–30: Align with CAMARA from the start
Avoid creating another proprietary API that partners must integrate differently from every other operator.
GSMA Open Gateway uses CAMARA specifications for its northbound service APIs. CAMARA is an open-source, vendor-neutral Linux Foundation project designed to create common API definitions across operators.
During this stage, map your chosen capabilities against the relevant CAMARA specifications.
Also define authentication, consent, authorization, error handling and the data each API exposes.
This work matters. Standardization reduces the operator-by-operator integration problem that has historically limited network API scale.
Days 31–45: Build the service layer
Now connect the standardized API to the actual network capability.
This is where operators often discover that API exposure is not the difficult part. The difficult part is connecting provisioning, charging, governance, reporting and legacy network systems without creating another one-off integration.
Our own AI CPaaS architecture is built around this problem. hSenid CPaaS exposes capabilities including SMS, OTP, charging, USSD, IVR, voice and location through a common platform layer so they can be consumed repeatedly instead of rebuilt for each partner.
Keep the first release narrow. Get the end-to-end path working before adding more APIs.
Days 46–60: Build the developer journey
By day 60, someone outside the network team should be able to understand what the API does and start testing it.
That means you need more than an endpoint.
Set up:
- developer registration
- API credentials
- documentation
- sample requests
- a testing or sandbox environment
- application provisioning
- usage visibility
- support and escalation paths
Then test it yourself.
Give the documentation to someone who did not build the API and ask them to make the first successful request. Every question they need to ask your engineering team is friction you should remove before launch.
GSMA’s current Open Gateway work also covers operational APIs for catalogue access, application-provider onboarding, product ordering, consumption and usage reporting.
Days 61–70: Put money around the API
Do not launch first and decide how to charge later.
Define the commercial model while the technical team is finishing the service.
Depending on the capability, pricing may be based on usage, transactions, sessions or subscriptions.
hSenid AI CPaaS supports usage-based, message-based, session-based and subscription-based models.
Also decide who gets billed.
Will you sell directly to enterprises? Through aggregators? Through CPaaS partners? Through revenue sharing?
There is no single answer, but there must be an answer before production traffic starts.
Days 71–80: Put real partners through it
This is where the launch becomes real.
Select a small number of developers, enterprises or channel partners and ask them to complete the journey without special treatment.
Can they register?
Can they understand the API?
Can they provision an application?
Can they make a successful call?
Can you measure their usage?
Can you bill it correctly?
Fix what breaks before expanding the program.
Certification and technical availability are not the finish line. GSMA noted in September 2026 that standardized APIs still need enterprise demand, easy developer onboarding, sales qualification and repeat usage before they become meaningful commercial products.
Days 81–90: Launch, measure, then add
The first dashboard does not need dozens of KPIs.
Track five:
API calls, active developers, active applications, onboarding completion time and revenue.
Then watch where adoption stops.
If registrations are high but API calls are low, investigate onboarding.
If calls are high but revenue is weak, revisit pricing.
If one API drives most usage, invest there before expanding the catalogue.
One number from our own operating footprint shapes how we think about this: hSenid Mobile systems handle nearly 50 million transactions daily.
At that scale, the job is not simply to make an API work once. Provisioning, charging, governance and reporting all have to keep working as usage grows.
What should exist on Day 90?
Not a finished network API strategy.
A working commercial loop.
A developer discovers an API. They understand the use case. They onboard. They integrate. The network delivers the capability. Usage is measured. The operator can charge for it.
Once that loop works for two APIs, adding the third becomes easier.
That is how a network API program moves from a technical initiative to a repeatable business.
