How to modify Query parameters in URL

Query Parameters are an important part of a URL. When you want to pass data in an HTTP GET request, the data is sent as query parameters.

Most e-commerce websites implement filtering and sorting through query parameters, we can update those values and check how the server responds. Query parameters are also used in implementing pagination and allow’s users to bookmark or share specific states or views of an application.

Use Cases:

1. Remove UTM tracking parameters.
2. Testing the server’s behavior by passing different query parameters.
3. Sending additional Information to some API calls to inform your backend & database that this is internal testing.

Modifying Query parameters using Requestly browser extension

Query Params rule can be used to perform the following modifications on a given URL:

1. Add new query parameters.
2. Remove a specific query parameter.
3. Remove all parameters.
