What is an API?
An API also known as Application Programming Interface, acts as a middleman between different software programs, allowing them to communicate and exchange data with each other. It's a set of rules and specifications that define how these programs can interact and share data with each other. By providing a medium between applications, they enable seamless data exchange, faster development, and innovative features, ultimately making your business operations smoother and richer.
What are the types of APIs Acefone offers?
Acefone offers several types of APIs to tailor your business phone system according to your unique operational requirements. Explore these APIs at Acefone’s API Docs.
How do APIs work?
Voice APIs act as a bridge between VoIP systems, which handle the actual voice calls over the internet, and other applications. These APIs translate spoken language into instructions the VoIP system can understand and vice versa. This translation allows applications to leverage VoIP features like initiating calls, sending voice messages, or transcribing conversations.
How many API types are there?
Despite the different classification that determine the number of API types, they can be narrowed down to three.
-
By Access
Public APIs, Private APIs, Partner APIs
-
By Purpose
Web APIs, Database APIs, Payment APIs, Voice API, SMS API
-
By Design
REST APIs, SOAP APIs, GraphQL APIs
