URL Encode for Query Parameters
Quick Answer: When building URLs with query parameters, special characters must be percent-encoded. Spaces become %20 (or +), & becomes %26, = becomes %3D. Paste your parameter value to get the correctly encoded string.
FAQ
Should spaces be encoded as %20 or +?
In query strings, both are valid. %20 is standard (RFC 3986). + is the HTML form encoding convention (application/x-www-form-urlencoded). Most servers accept both.
Do I need to encode the entire URL?
No. Only encode the individual parameter values, not the full URL. Encoding the full URL would break the protocol, domain, and path structure.
