Filtering with query parameters

Using URL query parameters to filter API responses is a common practice in web development, particularly when working with RESTful APIs. Query parameters allow clients to specify certain criteria for the data they are requesting, effectively filtering the response from the server based on these parameters. Here's a basic overview of how this works:

Understanding URL Query Parameters

1. Structure of a URL with Query Parameters:
   • A typical URL with query parameters looks like this: https://example.com/api/items?param1=value1&param2=value2
   • Here, ?param1=value1&param2=value2 represents the query parameters.
   • param1 and param2 are the keys, and value1 and value2 are their respective values.
2. Multiple Parameters:
   • Multiple query parameters are separated by the & symbol.

How They Are Used in APIs

1. Filtering Data:
   • APIs can use these parameters to filter results. For instance, in a user API, you might use https://example.com/api/users?age=25 to get users who are 25 years old.
2. Sorting and Pagination:
   • They can also be used for sorting (e.g., sort=age_asc) and pagination (e.g., page=2&limit=10).

Note: The '=' operator typically denotes equality, '!=' denotes inequality, and 'contains' checks if the field includes a specified substring.
