A developer must configure permissions for an Open Commerce API resource on a sandbox instance...

For configuring permissions for an Open Commerce API resource, the essential properties needed are: A. Resource_id - This property specifies the identifier for the resource you wish to configure, which is crucial for defining the scope and target of the API permissions. C. Client_id - This property identifies the specific client application that the permissions apply to. It is essential for controlling which client applications have access to the specified resource. These properties ensure that permissions are correctly assigned both to the resource and to the client application accessing it, aligning with security and access management practices in Salesforce B2C Commerce.
