As a developer, you may encounter "Invalid URL Encoded Form Data" issues while building applications. This error can occur at various points while working with URLs and web queries, such as constructing a request, or using a URL template. In this article, we’ll discuss how to solve such issues.
What is URL Encoding?
In order to send data over the internet, certain characters in a URL need to be encoded in order to ensure a safe and efficient transfer of data. URL encoding is the process of replacing characters that are safe for URLs with an alternate encoding. Unicode characters can be represented in the URL using the percent-encoding scheme, where each character is encoded as a percent symbol followed by the two-digit hexadecimal code of the character.
How to Fix "Invalid URL Encoded Form Data" Issues
If you encounter "Invalid URL Encoded Form Data" errors in your applications, here are the steps you can take to troubleshoot and resolve the issue:
Check the encoding used in the URL: The URL should always be in UTF-8 encoding as this is the standard for web communication. If the URL is using a different encoding, then it needs to be converted to UTF-8.
Make sure all characters are valid: Once you've ensured the URL is in UTF-8 encoding, you need to check whether all characters in the URL are valid. If any invalid characters appear in the URL, the request is likely to fail.
Validate the request and response: Make sure the request and response contain all the required parameters and values. Also, ensure all the request parameters are URL encoded.
Configure web server: Configure the web server for the application to accept requests with URL encoded data. This can be done by adding the accept-encoding header in the request.
Update the code: Check the code to make sure it is properly URL-encoding and escaping all characters. This is especially important when URL-encoding or decoding data.

Why is it important to ensure that all characters are valid in a URL?
Ensuring that all characters in a URL are valid is important as any invalid characters in the URL could lead to failed requests.
How do I convert the URL to UTF-8 encoding?
You can use a text-encoding tool such as Iconv to convert the URL to UTF-8 encoding.
What is the accept-encoding header?
The accept-encoding header is an HTTP header that is used to tell the web server which encoding formats are acceptable in the response. For example, if you specify "gzip" in the accept-encoding header, then the server will compress the response using gzip compression.
