Commerce Cloud includes REST web service APIs you can use to provide integrations and extensions of the administration interface and the storefront. These APIs are implemented using Jersey (JAX-RS) version1.14.
The APIs use the OAuth 2.0 security framework for data exchange.
Developers register their application in Commerce Cloud, which generates a JWT (JSON Web Token) application key. If necessary, the key can be regenerated to revoke existing access. For more information, refer to Register applications in Extending Oracle Commerce Cloud.
