Glossary
A specific URL on Meta's servers that an application calls to send messages or fetch data.
An API endpoint is a defined URL through which an application interacts with a service — sending requests and receiving responses. On the WhatsApp Cloud API, endpoints exist for actions like sending a message, uploading media, managing templates, and registering a phone number.
Developers (or the platform built on top) make authenticated HTTP requests to these endpoints with structured data, and Meta responds with results or confirmations. Inbound events flow the other way through webhooks. Together, endpoints and webhooks form the complete request-and-receive picture of the API.
Most businesses never touch endpoints directly — their provider's software calls them — but understanding the concept clarifies how WhatsApp automation actually works.
Endpoints are the building blocks of every WhatsApp automation; knowing they exist clarifies what a provider's software is doing for you.
Defuser AI handles all endpoint calls behind a no-code interface, so you get the power of the API without touching WhatsApp Business API code.
