# Outbound web services

You can use any of several outbound web services to integrate with ServiceNow applications, including REST and SOAP.

-   **[Outbound REST web service](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_OutboundRESTWebService.md)**  
ServiceNow outbound REST functionality allows you to retrieve, create, update, or delete data on a web services server that supports the REST architecture.
-   **[Outbound SOAP web service](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_OutboundSOAPWebService.md)**  
The SOAP Message module can be used to develop, prototype, and save outbound SOAP messages that can be reused in business rules and scripts.
-   **[Outbound web services: Logging](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/outbound-request-logging.md)**  
Log requests and responses for outbound web services such as REST and SOAP.
-   **[Outbound web service mutual authentication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/web-services/c_OutboundWebServicesMutualAuth.md)**  
Mutual authentication establishes trust by exchanging Secure Sockets Layer \(SSL\) certificates.
