+== cURL JSON Payload Issues in Windows vs Mac/Linux Systems ==
+'''1. Problem'''
+Error encountered when executing the following cURL command on Windows:
+<pre>
+Invalid JSON payload received. Unknown name "": Root element must be a message.
+</pre>
+'''2. Solution'''
+Windows system:
+<pre>
+curl -X POST -H "Content-Type: application/json" "API_URL" -d "{\"key\":\"value\"}"
+</pre>
+Mac/Linux system:
+<pre>
+curl -X POST -H "Content-Type: application/json" "API_URL" -d '{"key":"value"}'
+</pre>
+PHP code:
+<pre>
+$is_windows = strtoupper(substr(PHP_OS, 0, 3)) === 'WIN';
+if ($is_windows) {
+    $command = sprintf('-d "{\"key\":\"%s\"}"', $value);
+} else {
+    $command = sprintf("-d '%s'", $json_payload);
+}
+</pre>
+'''3. Problem Description'''
+* Root cause: Windows and Mac/Linux handle quotes in shell commands differently
+* Windows: Requires double quotes and escaped internal quotes
+* Mac/Linux: Can use single quotes to wrap the complete JSON string
+* When using incorrect quote formatting, the JSON payload is parsed incorrectly, causing the API to return a format error message
