Here are some of the most common use cases: - **Security**: With an SMS API, you can enhance the security of your platforms and protect your customers' sensitive information using [two-factor authentication (2FA) via SMS](/sms/2fa). For example, [Yousign](/customer/yousign), a digital signature provider, integrated our SMS API to deliver OTPs to users for identity verification before signing documents. This process significantly improved security and streamlined the signing process for their clients. - **Support**: You can use an SMS API to keep your customers and employees informed and supported with [real-time SMS updates and alerts](/sms/notifications). For example, [MrSpeedy](/customer/mrspeedy), a delivery platform, used our SMS and [Voice APIs](/voice) during the COVID-19 pandemic to ensure constant communication and support for their drivers and customers. - **Marketing**: You can use an SMS API to send promotional messages, coupons, and other marketing materials to a large audience. [Makro](/customer/makro), a prominent wholesale retailer, used our SMS API to run a targeted eCoupon campaign, aiming to help their customers benefit from government initiatives. By sending personalized eCoupons and [reminders via SMS](/sms/reminders), they achieved a 100% increase in conversion rates. The cost of an SMS API depends on several factors, such as the: - volume of messages being sent - destination country - type of sender - use case Regarding pricing, you should note that providers with lower prices might not have direct connections to operators, relying on inter-connections with other aggregators that could lead to lost traffic, impacting your delivery rates, times, and compliance. You should take advantage of free trials and demos to test the service and evaluate its features. For example, you can sign up for a free Infobip account and use a pay-as-you-go model to top up your account according to your needs. For more details on SMS pricing, feel free to contact our team. To use an analogy: imagine you want to send a letter. The SMS gateway is like the postal service, with its network of sorting facilities, trucks, and mail carriers. The SMS API is like your mailbox, providing a convenient way for you to drop your letter and interact with the whole system of the postal service.  So, an SMS gateway is the behind-the-scenes technology that handles SMS delivery, routing messages through a network of connections to mobile operators. The SMS API is a software interface that simplifies your interaction with this system, providing a straightforward way to send messages, receive replies, and access additional features offered by your SMS provider. The simplest way to categorize SMS messages sent via an API is to differentiate them based on the sending direction: - **Outbound messages**: These are messages sent from your application to mobile users. - **Inbound messages**: These are messages received by your application from mobile users. You can learn more about the types in our SMS API documentation. You can use our APIs to automatically send SMS messages based on events or triggers defined within your application. Learn more about it in this tutorial on automating payment reminders. ## An SMS API provider recognized for its excellence The industry experts have spoken.
