CORS is a W3C recommendation that enables Web browsers to request resources from origins other than their own (cross-origin request). For example, using CORS, a JavaScript script at https://www.example.com could request a resource from https://www.salesforce.com.
If a browser that supports CORS makes a request to an origin in the Salesforce CORS whitelist, Salesforce returns the origin in the Access-Control-Allow-Origin HTTP header, along with any additional CORS HTTP headers. If the origin is not included in the whitelist, Salesforce returns HTTP status code 403.
- From Setup, enter CORS in the Quick Find box, then select CORS.
- Choose New.
-
Enter an origin URL pattern.
The origin URL pattern must include the HTTPS protocol and a domain name, and may include a port. The wildcard character (*) is supported and must be in front of a second-level domain name. For example, https://*.example.com adds all subdomains of example.com to the whitelist.The origin URL pattern can be an IP address. However, an IP address and a domain that resolve to the same address are not the same origin, and you must add them to the CORS whitelist as separate entries.
