Learn how to consume SAP Concur API using Cloud Integration

1. On the SAP Integration Suite home page, You can find this pre-packaged content in the Discover section. Choose Discover > Integrations from the left menu and search for Connect to SAP Concur API. Choose the package SAP Concur API Integration with SAP Cloud Integration.
   
   

In the Overview tab of the package, you can find a detailed description of the package and the Artifacts tab shows the integration flows within the current package.

1. Choose Copy at the top left corner to Copy selected package’s content into your tenant.
   

   

2. After you’ve successfully copied your integration flow package, go to the Design > Integrations tab which you find in your left-hand navigation bar. You can now see a list of all existing integration packages as well as newly copied package with the title SAP Concur API Integration with SAP Cloud Integration on this tenant.
   

   

In next step we will create credential artifact and deploy it.

Before we configure and deploy this Integration flow we need the additional information
- Concur Credential Store: A SAP Cloud Integration OAuth2 Client Credential Artifact.
- Concur RefreshToken: which we have already used in the VS Code extension API Calls.

1. In the overview dashboard of your SAP Cloud Platform Integration Tenant, Choose Monitor > Integrations and then Security Material.
   
   
2. choose Create > OAuth2 Credentials.
   
   
3. Specify the following attributes:
4. Name : Name for the credentials.
5. Token Service URL : URL of the OAuth2 authorization server that issues the access token.
6. Client ID : ID of the client that you’re connecting to.
7. Client Secret : Secret key of the client that you’re connecting to

then, Choose Deploy.

1. When you refresh the Manage Security Material page, the new artifact is displayed (with Type OAuth2 Client Credentials) in the artifact table.
   

   

2. Take note of it we will be using it to configure the Integration Flow.

We need to upload the SSL Certificate a digital certificate that provide authentication and a secured connection. One of the easiest ways is to download the required SSL certificate from an appropriate website. Common browsers give users the option to download these certificates by exporting them.

1. Visit the website for the URL you wish to download the Certificate from. For instance, at https://eu2.concursolutions.com/home.asp, sign in with your login and password.
2. After logging in, notice the certificate information Pop-up by clicking the padlock icon before the URL
   
   
3. As shown below, click the Connection is secure link.
   
   
4. Click on Certificate is Valid Tab to bring up the certificate viewer to export the appropriate Certificate.
   
   
5. Click the Export button to export the certificate to the download folder.
   
   

We have already discussed we need a server certificate that needs to be uploaded to enable a secure SSL/TLS-based connection and have downloaded as well.

1. Return to the Integration Suite, Choose Monitor > Integrations then click on Keystore.
   
   
2. Choose Add > Certificate
   
   
3. Enter the** Alias** and Choose the certificate by browsing your local directory in the Add Certificate dialogue. Choose Add.
   
   
4. In the Manage Keystore, you can see the new Certificate is displayed with the Valid Until and Last Modified fields in the Entries
   
   

After you’ve successfully copied integration flow package, go to the Design tab which you find in your left-hand navigation bar. you can now see a list of all existing integration packages on this tenant. Select your newly copied package by clicking on the title Connect

1. Now we have everything to configure and update the Integration flow. Select the Artifacts and click on Action then Configure.

6. Select the default Sender and select Delete
7. Select the default Start message and select Delete icon.
   
   
8. Select and add the Timer integration step. The default property of timer integration step is to execute the integration flow immediately after you deploy the integration flow. More about the available timer configurations is available in help documentation.
   
   

It should be used as a subprocess integration flow that is called by another Integration flow on the SAP Cloud integration to retrieve data from any SAP Concur API with a GET request.

1. To establish inter-communication between integration flows we can use the Request Reply integration pattern with an ProcessDirect adapter. Search and Select Request Reply from integration palette and drop it into Integration Process.

• Change the name of Request Reply step to Get Expense Report in the General tab to improve readability.
• Select and connect the Get Expense Report integration step to the Receiver.
  
  

1. This would open the Adapter list. From the available Adapter select ProcessDirect in the Adapter Type option dialog.
   The Integration Flow which we have copied from the Catalog is a Consumer Integration Flow using ProcessDirect adapter you can consume it from other integration flow.
   
   
2. Under the Connection tab, enter Address as /Concur/API.
   
   
3. Search and Select Groovy Script from integration palette and drop it into Integration Process canvas.
   
   
4. Select the Groovy Script 1 Integration flow step and select the Create script icon.
   
   

5. In the script editor, you can specify the script according to the requirements of your scenario. For an overview of the classes and interfaces supported by the Script step, see SDK API. For more information on how to use the dedicated interfaces and methods for specific use cases, refer to Script Use Cases.

This is the Groovy script you can use to push the message log to the Response Payload. Copy and Paste it to script editor. Copy & Paste it.

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
def Message processData(Message message) {
    def body = message.getBody(java.lang.String) as String;
    def messageLog = messageLogFactory.getMessageLog(message);
    
    if(messageLog != null){
        messageLog.addAttachmentAsString("ResponsePayload:", body, "text/xml");
     }
    return message;
}

When you’ve finished the definition of your script, click OK

1. Select Save and then select Deploy to deploy the integration flow to SAP Integration Suite tenant. This will trigger the deployment of your integration flow. Note, the first-time deployment might take some time before the changes are fully deployed.
   
   
2. Navigate to Monitor-> Integrations tab to check the status of the deployed integration flow.
   Since the integration flow was designed as a Run immediate timer-based integration the flow will be executed as soon as it deployed. Select Completed Messages tile to view the successfully executed integration flows. In case of any failure, it will appear under Failed Messages.
   
   

1. Check the status of the newly created integration flow from the Monitor Message Processing. If status changes to Completed then go the Attachments Tab and click on Response Payload attachment.
