 **Authentication Requirements**: You must provide either:
 
 - `user` + `token` (API token authentication), OR
 - `remote-token` (remote trigger token authentication)
 
+**Parameters Format**: The `parameters` field accepts a multi-line string where each line contains one `key=value` pair:
+
+- Each parameter should be on a separate line
+- Format: `KEY=VALUE` (one per line)
+- Empty lines are automatically ignored
+- Whitespace-only lines are skipped
+- Keys are trimmed of surrounding whitespace
+- Values preserve intentional spaces
+- Values can contain `=` signs (everything after the first `=` is treated as the value)
