Frequently Asked Questions

Should I encode the entire URL or just parts?

Encode only the values of query parameters, not the full URL. Encoding slashes and colons in the base URL will break it.

What does %20 mean in a URL?

%20 is the URL-encoded representation of a space character. Other common codes include %3D for = and %26 for &.

Is URL encoding the same as Base64?

No. URL encoding uses % and hex codes (e.g. %20). Base64 uses a different character set entirely.

When do I need URL encoding?

Any time your URL contains characters outside A–Z, a–z, 0–9, -, _, ., and ~ you should encode those characters.
