Overview
Track every message your system sends
Use SMS API to send messages automatically from your systems when someone logs in, makes a booking, receives a delivery or makes a payment, or when a service disruption needs attention.
Send through the API, choose a sender and receive status updates. Developers, support staff and operations teams can see what was sent, what arrived and what needs follow-up.

What is SMS API?
SMS API is Viatel's API for sending text messages directly from your own systems. Developers and product teams use it to add SMS to your product or business systems, including OTP, reminders, notifications and bulk messaging.
What can we use SMS API for?
Use SMS API for one-time codes, verification, customer notifications, service alerts, reminders, campaigns and two-way messaging. It suits messages that should be triggered automatically by an existing system rather than sent manually from a browser.
How does Viatel's SMS API work?
Viatel's SMS API uses HTTP and supports GET and POST requests. Each request includes details such as the recipient, message and sender. Optional parameters support scheduling and other settings to suit your workflow.
Can we get delivery reports through SMS API?
Yes. Delivery reports let you track the status of sent messages. This is especially useful for service alerts, verification, customer notifications and other messages where you need to know whether an SMS arrived.
Does SMS API support two-way messaging?
Yes. SMS API supports workflows where recipients reply by text. You need a sender that can receive replies, usually a mobile number or another reply-enabled number. Viatel helps you choose the right setup for receiving and processing responses.
