An SMS API is an application programming interface that allows one platform or software to talk to another. In this case, the SMS API is built to allow businesses to integrate SMS messaging with existing software platforms using Notifyre’s SMS API. If you are using a specific platform, an SMS API will let you send and/or receive SMS directly via that platform, rather than having to switch to a different platform or software.
