Use /dwsso/oauth2 instead of /dw/oauth2 in all Account Manager URLs
All Commerce Cloud Account Manager endpoints starting with /dw/oauth2 (https://account.demandware.com/dw/oauth2) currently redirect to their corresponding /dwsso/oauth2 (https://account.demandware.com/dwsso/oauth2) endpoints. However, Salesforce will disable the /dw/oauth2 endpoint and the redirects will stop working. This means that for Account Manager, all the URLs starting with https://account.demandware.com/dw/oauth2/ must be updated to start with https://account.demandware.com/dwsso/oauth2/.
When: The /dw/oauth2 endpoint is now deprecated and beginning March 2026, the /dw/oauth2 endpoint will be disabled and redirects to /dwsso/oauth2 will no longer work.
Action: Replace all Account Manager endpoints starting with /dw/oauth2 (https://account.demandware.com/dw/oauth2/) with endpoints starting with /dwsso/oauth2 (https://account.demandware.com/dwsso/oauth2/))
Note: The Business Manager /dw/oauth2/access_token endpoint i.e. https://[Business_Manager_Hostname].dw.demandware.net/dw/oauth2/access_token which is provided by the B2C Commerce platform differs from the Account Manager /dw/oauth2/access_token endpoint and therefore remains supported and available for use.
