The Dynamic Request Parameter can populate a value that was transferred via:
Post Request (e.g. after a user is registered in an external CRM, a custom function could be coded to populate the user』s name onto the page.)Get Request (e.g a URL parameter could populate the value of the parameter onto the page)Query Vars Request (e.g can populate a field with data from any of the WordPress default Query Variables, such as the attachment ID.)
Note: WordPress maintains a list of reserved words that should not be used as request parameters. Doing so would result in a 404 Not Found error being returned. This is a WordPress function and is outside of Elementor』s control. See Reserved Terms list from WordPress.org documentation.
