Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.

API

An API (Application Programmable Interface) is how two machines or systems communicate and exchange information with one another. Each API comes with a specification that defines what parameters are passed between the machines through the API. There is one primary API used for SMS, and it is SMPP, but these days, REST HTTP based APIs are widely used.
