SMS APIs allow businesses to operate 24 hours a day, seven days a week. As a result, companies can update their customers, send promotions, and more without the need for human interaction at the point of contact, unlike other services like phone calls and manual emails.
An API is an application programming interface. Therefore, SMS APIs allow developers to integrate short message service (SMS), or texting, into their applications and programs.
With this technology, telecom companies are connected to the internet via API. This functionality removes the need for a middleman company or software to connect the application to the telecommunication company’s server and allows texts to be sent without manually logging on.
Furthermore, the customer that you text does not need internet access, as they would with email. As long as the receiver has a cell phone with texting capabilities, they will receive your message. The only caveat is that your customer must have expressly permitted you to message them, or you could be fined.
SMS APIs are beneficial for any entity whose customers would enjoy timely, streamlined updates through messaging. Some examples include:
Likewise, consumers will appreciate instant notifications of pertinent events and information. For instance, parents would often prefer a text about a snow day at school, which avoids the issue of missed phone calls. Many people also like reminders of when bills are due, shipments are delayed, and more. With SMS, the use cases are endless.
We live in a world of instant gratification. Customers expect instant access to information and answers to their questions and concerns. Companies that respect this need can preempt objections, anxieties, and queries by sending timely notifications. In this manner, they can stay ahead of their competition by providing top-notch service that builds consumer loyalty.
Furthermore, an SMS API can enhance the customer support experience—many APIs support FAQ and chatbot functionalities that provide instant answers to customer interests without live chat agents.
A quality SMS API should utilize encryption and two-factor authentication that keeps customer data private and provides peace of mind to end-users. In addition, the update intervals should occur frequently enough that scheduled notifications and time-sensitive information are sent when intended. Finally, the API and any call request limitations should be scalable as the company’s needs grow.
All SMS APIs are supported and made available in multiple developer programming languages and SDKs including:
