Hello IIIya, I am using /A_PurchaseOrder, but issue I am facing is I am unable to connect to the system with api.sap.com (APIKey) .

If you cannot access api.sap.com with your credentials (which usually must be the case), you must contact the SAP API group. Help information can be found at the bottom of the api.sap.com page. If you can access api.sap.com and successfully test the GET method A_PurchaseOrder there, everything is fine and you can proceed with the iFlow configuration.

Hi nkrishna,

Please try to do this:

Enter api.sap.com in your browser
Choose a product to explore -> click on S/4HANA Cloud
In the top switch from Overview to API's
In the line below switch from All to ODATA V2
In the right search field enter purchase order and press enter
Click on the ODATA V2 API Purchase Order tile
Click on the Try Out button
If you are not automatically signed in, use your credentials to log in
In the left navigation bar, scroll down and expand Purchase Order and choose the GET API (do not use the Subcontracting Components API)
Enter 15 in the $top parameter field
Click on the Run button
As the result you will see the S/4HANA Cloud sandbox URL in the Request URL field
and the first 15 purchase orders in the request body.
Copy now the API Key from the right button Show APIKey and the Request URL
Enter these informations into step 19 of your iFlow configuration.

BR,
Illya

Hello lllya,

Many thanks for your kind advice and assistance to resolve my issue, appreciated. 

I followed same steps you suggested and the Request URL which I received is "https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_PURCHASEORDER_PROCESS_SRV" and APIKey TSU1f4dbpstPqUYFKV49dlHrV8Kan055. After entering this details, I am getting error message,v "failed to connect to the system".

Not sure where is the problem!!

[Illya]

Why do you want to connect to the sandbox system explicitly, since this is not described in the learning journey...?

[nkrishna]

Hello Illya, When I logon with my user in the api.sap.com,I am getting Request URL as sandbox.api.sap.com by default and APIKey is generated for sandbox.api.sap.com URLs. For this reason I am using sandbox.api.com request URL. Let me know whether any other way to get APIKey for api.sap.com request URL. Thanks for your response, really appreciated.

[Illya]

That is correct. Both Request URL and APIKey must now be entered in the iFlow step (OData Connection). You will see if it works or not at the end when everything is configured.

Hello lllya,

Today I have tried the request URL  & APIKey using postman https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_PURCHASEORDER_PROCESS_SRV.

I am getting 401 unauthorized error. May be this is the reason why I am unable to proceed with the connection step. Can you please guide me

[Illya]

Can you start the GET request without errors from the api.sap.com page without going through the sandbox.api.sap.com as explained in the learning journey?

[Illya]

Are you using /A_PurchaseOrder at the end of sandbox URL (..._SRV/A_PurchaseOrder)?

[Illya]

Hi Nagendra,

You need to configure the connection between the Request&Reply and the Receiver.

Click on the OData connection element and select the Connection tab there to enter the API URL and any other required input.

By the way, when I click on the link I provided, it takes me to the SAP API Business Hub page... There you can directly get the API Key as described.

BR,
Illya

Hello IIIya, I followed all your steps, where there is differences is , 1) I am using CPI trail version 2) In api.sap.com , URL generated is for sandbox - https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_PURCHASEORDER_PROCESS_SRV/A_POSubcontr... (3) APIKey , I used in the content modifier header property with value TSU1f4dbpstPqUYFKV49dlHrV8Kan055. Please let me know whether you are able to configure with this details. Sorry for sending too many messages. But issue is not getting resolved

If you cannot access api.sap.com with your credentials (which usually must be the case), you must contact the SAP API group. Help information can be found at the bottom of the api.sap.com page.
If you can access api.sap.com and successfully test the GET method A_PurchaseOrder there, everything is fine and you can proceed with the iFlow configuration.

Hello Nagendra,

Please pass the header name APIKey  in receiver odata adapter request header section ( in addition to Ilya suggested changes ) then you should be able to resolve the issue.

Hello Sriprasad, I am unable to move to second step where you are suggesting me to pass the APIKey, in my case I am getting error message in step 1 itself where we provide address
