Noxitel OTP API review
SMS and voice OTP API with carrier failover, delivery reports, and analytics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Noxitel OTP API is a managed one-time-password service in Noxitel’s CPaaS platform, aimed at teams that need to send and verify codes through SMS or voice. Its REST API provides separate send and verify endpoints, with the verification request using a returned reference and the entered code. The service is cloud-based and accessible through web and API interfaces, making it relevant to small, mid-market, and enterprise teams that can integrate an API into their authentication flow. Stated coverage is 190 countries.
The product’s operational focus is routing and visibility. SMS messages include delivery reports, while voice OTP supports authentication calls; automatic carrier failover and direct operator connections are intended to help route delivery. Webhooks provide real-time events, and the dashboard includes analytics and campaign reporting. Noxitel also lists SMS carriers, WhatsApp Business, RCS, and Voice among its integrations, although the central verification methods described are SMS and voice. This combination suits teams that need delivery signals and channel fallback rather than a standalone code-generation library.
According to Noxitel’s pricing information, the service uses live, country-level usage rates rather than fixed OTP subscription plans, with rates depending on destination and channel. It is paid and has no free plan; numeric costs require selecting a destination and channel. The API uses HTTPS and Bearer API-key authentication. Listed support channels include email, chat, phone, and documentation, and 24/7 support is stated. Noxitel lists SOC 2, ISO 27001, GDPR, and SSO/SAML. Choose it when SMS-and-voice delivery with failover and reporting fits the workflow; teams seeking a free plan or verification methods beyond those channels should compare alternatives.
