An API Response is the data or information that is returned from a server when an API (Application Programming Interface) request is sent. It is typically in the form of a JSON or XML document and contains either a status (“ok”, “error”, etc.) or data (e.g. a list of items).
The response is important because it provides the client with the data they requested. To build an analogy, we can use an automatube journey. When a passenger submits their ticket, the automatube machine will respond with the data for their journey, such as the route, time, and any other necessary information.
In the same way, an API request will send data to the server, such as user credentials or allowances, and the server will respond with the data it has regarding the request. An example of this might be an ecommerce platform where a user logs in and requests their purchased items. The server will respond with the user’s order details, such as total price, purchased items, and shipping details.
Overall, an API Response is crucial for a successful API call and is the information that a client receives. The data is usually in the form of a JSON or XML document, and contains either a status (“ok”, “error”, etc.) or data (e.g. a list of items).
