For example, to use a parameter value of **user\\|title**, enter `user%7Ctitle`. Entering special characters directly may cause the REST message to fail and display the response Invalid uri <URI>: Invalid query.\n\n**Parent Topic:**[Create a REST message](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/t_ConfiguringARESTMessage.md)\n\n"}}
