Layer 3
Open APIs and TM Forum conformance
Business and service capability exposed to ISPs and RSPs, end customers, construction companies, partners and third-party ecosystems through conformant, TMF-numbered interfaces.
The point
Integration as configuration, not a project
When both sides implement the same TM Forum contract, onboarding a retail partner becomes a configuration exercise: credentials, scopes, catalogue mapping and test cases. That is the difference between a two-week onboarding and a two-quarter one.

Gateway and security
API Gateway and Integration Layer
Every external interface enters through one gateway, so security, quotas and observability are consistent rather than per-integration.
Identity and access
OAuth2 client credentials and authorisation code flows, scoped per partner and per API domain.
Transport security
HTTPS everywhere, with mTLS available for system-to-system partners.
Throttling and quotas
Per-consumer rate limits and quotas enforced at the gateway rather than in application code.
Monitoring
Request, latency and error telemetry per consumer, with alerting on SLA-affecting degradation.
Event streaming
Domain events published to subscribers, so partners react to state change rather than polling.
Webhooks
Registered callbacks with retry and signature verification for order, appointment and fault events.
Conformance
What conformance does and does not mean
Conformant interfaces remove the argument about payload shape. They do not remove the need to agree catalogue, SLA and process — so onboarding is scoped around those instead.
Handled by the standard
- Resource models, state machines and error semantics
- Qualification, ordering, activation and ticket lifecycles
- Event and notification structures
- Versioning expectations between parties
Still yours to agree
- Product catalogue and commercial terms
- SLA definitions and remedy
- Appointment rules and field responsibilities
- Settlement periods and dispute process
