Question 1

What is an SMS API?

Accepted Answer

An SMS API (Application Programming Interface) provides an integration platform to programmatically send and receive SMS messages.
SMS API provides an easy-to-use interface to integrate messaging into your marketing and customer service programs. You can reliably send SMS to your audience, for use cases such as alerts and notifications, feedback and surveys, payment reminders, and verification codes/ OTPs.

Question 2

What can I use SMS API for?

Accepted Answer

An SMS API makes it easy to connect to an SMS gateway and send messages at scale in a reliable and secure way. Some of the uses and benefits include:

Send and receive messages such as alerts, notifications, transactional messages, and more
Connect with customers in different countries without worrying about technical details like carrier, deliverability,
pricing differences, etc.
Review message delivery and status in real-time
Queue messages for delivery

With SMS API, you get high deliverability even when a large number of messages are sent at the same time, along with insights into which messages are being delivered, which aren’t, and why (or why not). Businesses can send bulk messages, customize sender ID by country, and get real-time delivery receipts - all while ensuring regulatory compliance of their country.

Question 3

How can I integrate the SMS API?

Accepted Answer

An SMS API is a basic building block that makes it possible for brands to connect to an SMS gateway easily and eliminates the need to use manual SMS systems.

The integration of SMS API is managed by a software developer. It requires programming, server configuration, data modelling, testing, etc. to communicate with the API, and connect it with the SMS gateway.

It’s easy to build a test integration in just a few hours. For example, to integrate Gupshup’s SMS API from PHP, all you have to do is sign up with Gupshup, create a sender ID, create an API key, and install our PHP code library into your application. Once the PHP API is integrated into your software, you can start sending automated SMS messages from your
application.

Question 4

What is DLT registration?

Accepted Answer

As per the recent guidelines by Telecom Regulatory Authority of India (TRAI) , it is mandatory for a business to register on the Distributed Ledger Technology (DLT) platform, a block-chain based registration system before sending bulk SMS to its customers. This is aimed at creating more transparency and reducing the incidence of spam and fraud done through SMS. A business entity has to register itself on the DLT portal, register Sender IDs and submit message templates.

Question 5

Does it cost money to send SMS?

Accepted Answer

Sending SMS messages via a mobile carrier may involve a charge. Some carriers also charge for receiving SMS messages. These costs can add up, depending on factors like the text volume, message type, countries sent to (or received from), price per message, etc.
With an SMS API provider you can send SMSes to customers in dozens of countries at a much lower rate than you would with regular carrier-based SMS. Gupshup offers pay-as-you-go pricing so you only pay for what you use with full transparency and full flexibility. You can send local and international messages, SMS to toll-free numbers, and more. All messages are sent programmatically, and the API is easy to set up, enabling rapid go live.
