An API endpoint is a specific digital location where requests for information are sent by one program to retrieve the digital resource that exists there. It is one end of a communication channel, and when an API interacts with another system, the touchpoints of this communication are considered endpoints. For APIs, an endpoint can include a URL of a server or service. Endpoints specify where APIs can access resources and help guarantee the proper functioning of the incorporated software. APIs work by sending requests for information from a web application or web server and receiving a response. An APIs performance depends on its capacity to successfully communicate with API endpoints. Software programs typically have multiple API endpoints. Developers list all endpoints of their API in the documentation so that users know how to access the resources they need. In summary, an API endpoint is a specific location within an API that accepts requests and sends back responses.
