Definition
An Application Programming Interface (API) is a set of rules that lets different software systems communicate. Voice AI platforms expose APIs so agencies can integrate calling, leads, and data with CRMs and other tools.
Why it matters
APIs are what make voice AI integratable with a client's existing tools, a key selling point for agencies.
