API tips

🔌

Query parameters containing spaces, ampersands (&), or equals signs (=) must be percent-encoded before being added to a URL.

💡

Use encodeURIComponent for individual parameter values, not encodeURI — encodeURI leaves characters like & and = unencoded.

🛡️

Never append user input directly to a URL without encoding it. Unencoded input can break your URL or create injection vulnerabilities.

📋

After encoding, paste the result into your API client (Postman, curl) or directly into your code as a string constant.
