Working with API definitions
An API definition specifies the complete configuration for an API. You can create and configure your APIs either by using either the API Designer UI application, or by using the browser-based API Manager UI.
Note: In the 
Help page of the API
Manager, and API Designer user interfaces,
click the Product information tile to find out information about your product
and Git package versions. The API Designer product information
is based on its associated management server, but the Git information is based on where it was
downloaded from.

following terms:
- OpenAPI Specification
- The OpenAPI Specification defines a standard, language-agnostic interface to RESTful APIs. API Connect supports version 2.0 and version 3.0 of the OpenAPI Specification.
- OpenAPI document
- One or more files that describe an API conforming to the OpenAPI Specification.
- OpenAPI definition
- The description of an API that conforms to the OpenAPI Specification. In API Connect, you can create the API definition by filling in settings and properties, or by importing an OpenAPI document that contains an API definition that you want to work with.
The following topics provide full details for creating and configuring your APIs.
