Our Services — Answered
Which channel should I choose for OTPs?+
For speed, our Flash OTP Gateway delivers in under 0.5s. For resilience, add WhatsApp authentication as a fallback. For complete fail-safety, Voice OTP covers users on congested towers — Tekhook chains all three automatically.
Can I use multiple services on one account?+
Yes. A single Tekhook account and API key works across SMS, WhatsApp, RCS, Voice and Email. You choose the channel per dispatch or let our smart fallback engine decide based on delivery.
Do you provide a sandbox for testing?+
Every account includes a free sandbox with 10,000 test credits, webhook testing and Postman collections — so you can validate integration before going live and spending real credits.
How is delivery reported back to me?+
Real-time Delivery Receipts (DLR) are pushed to your webhook per message, and visible in the live analytics dashboard with status, latency and operator breakdown for full auditability.
