Query String Builder
Query String Builder helps you build a query string from key/value lines in the browser so you can assemble links, redirect parameters, and filter states without hand-encoding every value.

Redirect and tracking links become error-prone when query parameters are assembled by hand. This guide covers a safer browser-based workflow for building query strings, validating the final URL shape, and checking the output before launch.

Step-by-step workflow
- Draft the key/value pairs in Query String Builder instead of concatenating parameters manually.
- Encode any values that include spaces, punctuation, or copied text from another system.
- Run the final result through URL Parser or Query String Parser to confirm every parameter landed where you expected.
Example
This example shows the kind of input and result shape that usually appears in this workflow.
Example input
utm_source=newsletter
utm_medium=email
utm_campaign=spring launchExample output or next step
?utm_source=newsletter&utm_medium=email&utm_campaign=spring%20launchFAQ
Why not build redirect parameters manually?
It is easy to miss separators, double-encode values, or leave raw spaces in a URL when you assemble long query strings by hand.
Which tool should I use after building the string?
Use Query String Parser or URL Parser to verify the final result before you publish a link or redirect rule.
Is this useful outside of redirects?
Yes. The same workflow works for tracking links, filter links, signed URL prep, and API requests that depend on query parameters.
