What is an SMS API?
An SMS API (Application Programming Interface) is a set of programming instructions that allows developers to integrate SMS (Short Message Service) functionality into their applications, systems, or platforms. With an SMS API, developers can automate the process of sending and receiving SMS messages by writing code that interacts with the SMS gateway provided by an SMS service provider.
Using an SMS API, developers can perform various tasks, such as sending bulk SMS messages, receiving SMS messages, retrieving delivery reports, and managing contacts and groups. The SMS API can be integrated into various types of applications, such as mobile apps, web apps, and desktop applications, and can be used to send different types of SMS messages, including text messages, multimedia messages, and short codes.
How an SMS API works
With an SMS API, you can equip your software or application to enable automated SMS messaging services. The process of sending SMS messages via an SMS API involves the following steps:
- Authentication: The business sends a request to an API server, authenticating itself with a unique key or token.
- Message composition: The business creates a message, including the recipient’s phone number and the content of the message.
- Sending the message: The API server receives the message and sends it to the recipient’s phone number via the SMS gateway.
- Delivery receipt: The API server receives a delivery receipt, indicating whether the message was successfully delivered or not.

Two-factor authentication (2FA): Send verification codes to users for 2FA, which adds an extra layer of security to the login process by confirming a user is in possession of their mobile device.
Alerts, reminders & notifications, and alerts: Send application to person (A2P) notifications and alerts to your customers, such as order confirmations, delivery status updates, appointment reminders, emergency alerts, and more.
Marketing campaigns: Send promotional and bulk messages to a targeted audience.
Customer support: Allow your customers to send person-to-person (P2P) text messages for support requests or inquiries. Or integrate a chatbot for automated support conversations.
Mobile verification: Verify a user’s mobile number during the registration process for a mobile app or service. This helps to ensure that users are providing accurate and valid phone numbers.
