Standard APIs Power Every Channel
Product, ordering, eligibility, balance, billing, payment, identity, address, and inventory capabilities are exposed once and reused everywhere.
The Business Challenge
Every new digital channel was paying the same integration cost again.
WOM customers wanted to sign up, upgrade devices, port numbers, and manage service through digital channels. But the systems holding pricing, eligibility, contracts, balances, billing, identity, and inventory were built to provision and bill services—not to serve web, mobile, and chatbot experiences directly.
Without a common service layer, every new customer-facing channel needed to reconnect to the same legacy systems in its own way. That duplicated integration effort, slowed launches, and raised the cost of every new digital experience.
The business needed a way to expose core capabilities once, then let every channel reuse them without repeatedly rebuilding the plumbing underneath.
AAXIS built a shared TM Forum Open API service layer between WOM’s systems of record and every customer-facing channel, so the business could expose each capability once and reuse it across web, mobile, chatbot, and future experiences.
Build the capability once. Reuse it across every channel.
Product, eligibility, ordering, billing, identity, payment, balance, address, and inventory services now sit behind one shared business layer instead of separate point-to-point integrations.
How AAXIS Enabled It
The technology changed digital growth from repeated integration work into a reusable operating model.
Each capability was designed around a business outcome: more self-service, faster channel launches, less duplicated integration work, and a platform WOM’s own teams could continue extending.
- Postpaid Signup Became Self-ServiceCustomers can complete postpaid signup digitally instead of requiring a store or agent-led process.
- Number Portability Became a Digital TransactionNumber, provider, and device validation run during checkout so customers can port numbers without a manual handoff.
- New Channels Reused Existing Business CapabilitiesWeb, mobile, and chatbot experiences consume the same product, ordering, eligibility, billing, identity, payment, balance, address, and inventory services.
- WOM’s Own Team Took Over the PlatformWOM’s internal development team migrated onto the same APIs and continued extending the architecture after delivery.
- Chatbot Self-Care Became a Change RequestNew self-service experiences could be added on top of standard APIs instead of launching another integration program.
- One Shared Layer Served MillionsThe same digital foundation supports more than six million subscribers across acquisition, service, and account-management journeys.
The Business Impact
WOM created a lower-cost model for digital growth without replacing the systems that already ran the business.
By exposing business capabilities once and reusing them everywhere, WOM reduced duplicated integration work, accelerated new digital journeys, expanded self-service, and gave its own teams a platform they could keep building on.
