You can run REST messages from a MID Server which allows the message to communicate with REST providers on an internal network.\n\nServiceNow REST functionality is flexible enough to accommodate many web service APIs. Be sure you are familiar with your web service and the parameters it accepts before attempting to define a REST message in ServiceNow.\n\n-   **[REST message elements](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/r_RESTMessageElements.md)**  \nAn outbound REST message is composed of several elements, such as the endpoint and HTTP methods.\n-   **[Create a REST message](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/t_ConfiguringARESTMessage.md)**  \nSend requests to a REST web service endpoint by creating a REST message record.\n-   **[Outbound REST authentication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_OutboundRESTAuth.md)**  \nOutbound REST messages support multiple types of authentication.\n-   **[Variable substitution in outbound REST messages](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_VariableSubstitutionREST.md)**  \nYou can use variables when creating outbound REST messages and assign values to those variables when performing a request.\n-   **[Scripting outbound REST](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_ScriptingOutboundREST.md)**  \nYou can send outbound REST requests from any place in the ServiceNow AI Platform where scripting is allowed.\n\n**Parent Topic:**[Outbound web services](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/outbound-web-services.md)\n\n"}}
