What is URL encoding?
URL encoding (also called percent-encoding) converts characters that aren't allowed in a URL into a safe format. For example, a space becomes %20 and an ampersand becomes %26.
URL encoding is required when passing special characters in query parameters, form data, or API requests. Without it, characters like &, =, and ? would be interpreted as URL delimiters rather than data.
