Get familiar with REST APIs on Langstack. By the end of this section, you will acquire a deeper understanding of REST APIs, their creation, and their deletion.
The API template is used to build an API (an application programming interface endpoint) to perform business user-defined logic.
An API must have a base URL. A base URL is a text that is at the beginning of the URL, which consists of
the customer URL
The text dataapi
Group name for the API
API name
Path parameters
An API receives and processes web requests and returns response data to the requester. Any API request must end up with a response; failing to respond for any reason will make this request invalid.
Different operations can be executed through APIs. For example, users can:
Save data to and retrieve it from Entities,
Send data to and receive data from connected sources,
Combine and transform data from multiple sources and return everything as a single response.
API documentation is automatically generated. Users can share documentation internally or make it publicly available on the Internet.
An API can be used in multiple API gateways; however, one API gateway can use only one API at a time.
