FAQ

Is it okay to include spaces or non-English text in a value?

Yes, entered values are automatically percent-encoded, so spaces, non-Latin characters, and symbols all produce a correct query string.

Can I use the same key multiple times?

Yes, add multiple rows with the same key name to build array-style query parameters, like "?tag=a&tag=b".

What happens to a row with an empty key?

Rows with an empty key are ignored and excluded from the query string.
