Encode URL Parameters for APIs
Safely encode query string parameters before appending them to API request URLs.
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 β 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.
