Consume a Stripe service from SAP Open Connectors and SAP Cloud Integration to create payment transactions

1. Go to your Open Connectors portal and enable a Stripe Connector, place your pointer in the connector and click in Authenticate. Bear in mind that this step by step tutorial is for demo purposes.

   

2. Search your Stripe secret Key and copy it into the Stripe connector as the API Key.

   

3. Go back to your Open Connector portal and add a name and create the connector’s instance.

   

4. Click on “Test in the API Docs”.

   

5. Run a quick test by getting the balances.

   

1. Copy your Open Connectors credentials. You are going to use them to enable the credentials in Cloud Integration.

1. Go to you Cloud Integration environment. In the eye icon (Monitor), in the Manage Security Material tile, create an User Credentials artifact.

1. Go to the pencil icon (Design) and create a new package:

   

2. Go to the Artifacts tab and create an Integration Flow, name it as you want:

   

1. Click on your Integration Flow to start designing it. Then, click on Edit and change the Sender name. Type “AppGyver” as the application sending the call request to this IFlow, in the Sender box.

2. In the connection tab, add a path to the “address” and uncheck the CSRF box, you are not going to enable it for this Integration flow (IFlow).

   

Before doing any data storage or message mapping, configure the IFlow to test the call to stripe.

1. Change the Receiver name to “Stripe”
2. Add a Request Reply task in the IFlow, select Open Connectors as the adapter
3. Select the Open Connector adapter, go to the connection tab, and add:
   • The API endpoint as the base URI (this one you get from testing the connector as illustrated above)
   • Select the credential you just created stripeOpenConnectors
   • In Resource, select the API path to create charges in Stripe, which is “charges”
   • Change the method to POST, as you are going to execute a POST call.
   • Leave JSON as the format.
   

4. Save and Deploy the IFlow.

1. Click on the eye icon and wait until the Integration Flow is deployed. Once it is, copy the API endpoint and change the log configuration to “trace” to trace the messages passing through the IFlow.

   

2. Go to Postman. Enter your SAP BTP account credentials with Basic Auth, modify this following JSON with your Stripe data and use it as the payload for testing with Postman:

   JSON

   Copy

   {
       "amount": 21234,
       "customer": "<stripe customer id>",
       "currency": "<currency selected in your stripe account>",
       "source": "<card id>",
       "description": "My test from CPI & Postman"
   }
   

Like this:

1. Go back to your Cloud Integration and click on “Monitor Message Processing” to monitor the request.

1. Click on “Trace” in the logs..

1. Check how it worked from the CPI side.

Now you’ve successfully integrated a 3rd party connector leveraging SAP Open Connectors’ content, with SAP Cloud Integration, in this case to execute payment transactions with Stripe.

As a next step, you are going to add the request call to SAP Sales and Service Core (formerly SAP Cloud for Customer or C4C) to create a Sales Order. But first you need to set up the needed payload message for the Message Mapping before calling the SAP Sales and Service Core API.
