REST API Integration

[former_member1284633]

What is the prerequisite for integrating SAP Order Management Foundation into our system? Please provide the integration methodology of REST API.

Hello Saurav,

In order to better understand your question, let me ask how your system looks like?

SAP Order Management Foundation offers an API (see API Business Hub) which you can use to connect to in your coding.

In addition, there are also predefined Integration Flows offered, for example towards S/4HANA Cloud.

Best Regards

Stefan

We are trying to consume SAP out-of-box Rest API from USAA Infra, using a Postman App

2.1 Is it the application server that hosts the SAP Rest Services ?

Is it Dev Environment Is it DS4, DFJ, DFS, DCL
Online forum suggested that we can use Port 6405 for REST API. When we tried this port, it was not accepting connections.

Essentially What is the hostname and the Port number where the REST Services are being served ?
2.2 How do we authenticate with the Rest Service, Is it Basic Auth or MTLS ?

Hello,

If you want to consume SAP Order Management foundation API's, you have to, beside licensing the product:

1. have prepared your SAP BTP, Cloud Foundry environment (including assigning the entitlement, creating the service instance and a service key), see SAP Help

2. then you can retrieve the base URL for the API from the list of endpoints in the service key and construct the complete URL by adding the path as mentioned on the API hub ( base url + path)

3. Before sending a request to the API, you first have to follow the oAuth2 protocol and fetch a JWT token from xsuaa (credentials and URL can again be found in the service key).

4. Now you can construct your postman call with filling the complete URL (no port needed) and choosing Authorization type "Bearer Token", where the value is the retrieved "access_token" value from the xsuaa response.

Hope this helps further!

Hi Stefan, stefan.weidemueller-schmidt

Thank you for your response!

We have license to S4HANA, Solution Manager ABAP, SAP Cloud Connector in our SAP landscape running on NS2 Cloud. What APIs do we have access to given this landscape ?
