Recently Jerry is working on an integration project about creating orders in Wechat platform by consuming SAP Commerce Cloud Restful API.
Consultants who didn't touch SAP Commerce before(such as Jerry ) might get confused once they saw the search result by key word "commerce" in https://help.sap.com:
Several products with similar name are listed in search result.
SAP Commerce：SAP commerce solution based on On-Premises deployment approach
SAP Commerce Cloud on SAP Infrastructure & SAP Commerce Cloud on Public Cloud: as their names give a very clear hint: both are SAP Commerce solution based on cloud, and differentiated by the underlying cloud infrastructure the solution are running. SAP Commerce Cloud on SAP Infrastructure are sometimes called Commerce Cloud Version One and CCV1 for short, while the latter called CCV2.
Execute the application, and we can observe the successflly created order with its ID in callback function in line 20:
Search the ID in Commerce Cloud backoffice UI to check the details of created order.
As introduced before, it's necessary to go through five steps to have an order generated. And in Jerry's project there are totally seven "step.js" implementation files, why?
For the additional two step.js, one is for access token retrieve and the other for cart delivery mode set operation. Access token will be appended to the header fields of all the subsequent API calls for authorization purpose. And the cart delivery mode will be set implicitly if performed in storefront UI via browser whereas an explicit API call is necessary in our case. As a result totally seven HTTP roundtrip is needed in API consumption case.
The access token fetch is implemented by following OAuth protocol: send the OAuth Client ID and secret to SAP Commerce Cloud OAuth endpoint to get the issued access token.
First we have to create a new OAuth Client in SAP Commerce Cloud backoffice:
Then in file "step1_get_token.js", send a HTTP POST to Commerce Cloud Authentication endpoint to request access token:
For privacy reason I didn't upload urlconfig.js to github which contains the dedicated url of my own Commerce Cloud API endpoint. Instead I upload the template file: urlconfigTemplate.js. Just replace the place holder marked with "<>" with your actual value there, rename the template file back to urlconfig.js. After that you can create orders in your own Commerce Cloud tenant.
