Nigeria-ready

Built for Nigerian delivery realities

The product language is global SaaS. The operating details are local: naira billing, sender IDs, DND realities, WhatsApp onboarding and support hours that match your team.

DND-aware routing

Approved transactional traffic gets handled with the routing care Nigerian numbers require.

Sender ID support

Guidance on registration requirements, documents and status across networks.

Naira billing

Top up a wallet in naira and spend it across SMS, Email, Voice and WhatsApp.

Consent and opt-out

Campaign tooling is designed around opt-in records, unsubscribe handling and exportable logs.

Developers

APIs your team can trust in production

Clear request shapes, sandbox testing, idempotency keys, predictable errors and signed delivery webhooks for every important message state.

Sandbox mode

Test channel flows without spending wallet balance or messaging a real customer.

Webhooks with retries

Signed payloads and retry behaviour help your team reconcile delivery events.

Idempotency support

Retry safely without sending duplicate messages for the same business event.
