Businesses worldwide are transitioning and embracing several digital strategies to communicate with their clients and remain competitive in their respective fields. To effectively communicate, there is a great need to send information that is short, relevant, and with a broad reach. The businesses achieve this through the use of secure SMS APIs.
An SMS API is a program that can activate the necessary codes that are essential to develop, send and receive messages through devices that support the technology. SMS APIs are functional across different mobile platforms and operating systems. The API gives the developers the ability to review, send and receive messages and check the status of the messages that have been sent. Their functional abilities allow them to provide access to responses without the need to get any authentication.
When a request is initiated to the API, it asks for a URL that contains the required information. This information includes the phone number, name and identification of the user and those of the sender. The API then sends the request through the short message services gateway server. The gateway server verifies that the parameters that have been set and specified are accurate before processing the request. A response is sent back for the request once it has been executed.
The users of this API are mostly companies and businesses that need to communicate with their clients frequently. The APIs are used to promote products and services to consumers. The secure SMS API provides a confidential and secure means to transfer this information between them and the consumers. They also use this API to send notifications in case of changes to their services or terms that may affect the client base.
This API assures the users of timely, reliable and efficient delivery of messages across an extended coverage.
There are several APIs for SMSs that are offered as freemiums, while others are free. The free APIs in this category include Nemo Verify, sms77io and Twilio.
All SMS APIs are supported and made available in multiple developer programming languages and SDKs including:
