  • Step 1
    1. Go to your SAP Build Apps custom app, click on Data on the menu and Add a Data Resource and select REST API direct integration. Remember that for this exercise, it is needed to create first a custom mobile application from this blog post.

      Creating a new API connection
    2. Copy and paste your API endpoint from SAP API Management as the base resource URL and name your Data Resource. Enter the name: IntegrationSuite_API_CORS.

      Adding API endpoint
    3. Click on the Create Record (POST) section, make sure id is erased from the relative path and enter your API Key as a header (make sure you don’t put it as optional and mark it as static).

      Adding the API Key as a header
    4. Set up the custom needed schema for testing a POST request. Remember the payload structure you are using for this exercise:

      "AppGyverSalesOrder": {
          "customer": {
          "ObjectID": "<Object ID from SAP C4C>",
          "BuyerPartyID": <BuyerPartyID from SAP C4C>
          "paymentData": {
          "amount": <Payment transaction amount to be processed in Stripe>,
          "customer": "<stripe customer id>",
          "currency": "<currency selected in stripe account>",
          "source": "<card id>",
          "description": "Test payment via CPI"
          "product": [
              "ProductID": "<Product ID from SAP C4C>",
              "Quantity": <Product quantity to be purchased>

      So to “translate it” into the custom schema in SAP Build Apps, you’ll need to add these properties manually, as shown in the following image:

      Adding the schema propertis for Payloads to be sent
    5. Click on the Test tab and open your custom object, where you are going to add the values as the payload for testing.

      Adding some values to test the call

      And setting for testing purposes a Product ID from SAP Sales and Service core (formerly SAP Cloud for Customer or SAP C4C).

      Set Product Id from SAP Sales and Service Core to test it
    6. Save it and now click on Run Test. You should see this response Status: OK:

      Test response
    7. If you check on your Stripe developers account, you can see the amount and description “Ta da!! Integration scenario is set up”:

      Test Stripe charge

  • Step 2
    1. Click on Set Schema From Response to let Build Apps know you want to create a variable for getting the receipt URL.

      Set schema from response
    2. Now you can see receipt_url from the return message, as a property, like in the following image. Save your configuration.

      Save schema from response
    3. Create a variable to enable this receipt_url as a variable to be linked in your application UI.

      Click again on Data to close it and go back to your application design. Click on View – Variables and click on Add Page Variable as it is in the following image:

      Create a page variable

  • Step 3

    Remember you’re following this previous exercise of a custom application developed in SAP Build Apps (as mentioned in the prerequisites first tutorial). The differences are:

    1. Add one field to the QR code ProductID for the purpose of the integration exercise and update the variables you’ve already created in the SAP Build Apps app. Of course, in reality you would want to add as many Product fields as necessary to execute the Sales Order transaction.

    2. Add an additional Button (to trigger the API call) and an WebView component (to see the Stripe’s payment confirmation with the receipt url).

  • Step 4
    1. Go back to your QR code generator (you can use this one), and paste this JSON object. You may need to change the model and URL too, if you want to test your integration with a different product defined in your SAP Sales and Service Core tenant (SAP Cloud for Customer):

      "ProductID": "<your SAP C4C product ID>",
      "model": "Samsung French Door 29 ft",
      "imgURL": ""

      Save the generated QR Code:

      Create a page variable
    2. Go back to your SAP Build Apps custom app, and click on View – Variables, go to Page Variables and update them by adding ProductID as a new property of the parsed Json object:

      Add Product ID into your page variable
    3. Click again in View – Variables to go back to your UI editor, change the first title of the Product from brand to the model page variable, to make it consistent with the generated QR code:

      Link you Parsed JSON defined page variable to the button
    4. Add the ProductID page variable to the second Product component:

      Link you Product ID variable to a text field
    5. Leave the image URL as it is in the original exercise.

  • Step 5
    1. Add the button and change its name to Create Order consuming CPI:

      Add a button
    2. Add the WebView component (this one, you have to install it):

      Add a button
    3. And link it to the page variable receipt_url you created before. Like this:

      Link the receipt url page variable to the WebView component
    4. Select the button and click on the bottom-right “Show logic for BUTTON” and add a Create Record logic component.

      • In the Resource name: select the Data Resource Id you created before IntegrationSuite_API_CORS
      • For the Records properties: here you’ll see the custom schema we created before for requesting POST calls from SAP Build Apps.
        Create Record Logic
    5. Click on Record properties -> Custom object. And add the newly created property: ProductID.

      Create Record Product ID

      After save it, you’ll see it like this in the Product List Object:

      Save Create Record

      If you want, you can create as may variables as you want to make the exercise more dynamic. As I mentioned before, for the purpose of the integration exercise I’m using only ProductID. You’ll see your payload structured in Build Apps, like this:

      Data Binding

      Click on Save.

    6. Add a JavaScript logic component, this is to configure the getting of the receipt_url from the Stripe request response.

      JavaScript Component
    7. Erase the original input1 name and change it for response. Click to bind the data.

      JavaScript Component

      Select the binding type: Output value of another node, then create record and select receipt_url as field you want to get from the response.

      Get Receipt URL from Response

      Save it and close it.

    8. Add a Dialog Toast, just to show up a message that the request call was successful. Write as a Toast Message Loading URL, like this:

      Add Dialog Toast Message
    9. Add a Set page variable logic component and add as the variable name the page variable you created before receipt_url:

      Set Page Variable
    10. Link the variable like this and save it:

      Bind Receipt URL to the page variable
    11. Do the same for assigning the value. Here you are going to link it with the receipt_url JavaScript component you created before:

      Bind Receipt URL as the assigned value

    Now it’s time to test the app and the whole integration.

  • Step 6
    1. Grab your phone and enter your SAP Build Apps mobile app. Link it to your account as explained in the original exercise. Read the generated QR code:

      Product QR Code
    2. Click on Create Order consuming CPI and you’ll see that the order was successfully created. Like this:

      AppGyver Complete Test
    3. Check in the SAP Sales and Service Core tenant (formerly SAP Cloud for Customer / SAP C4C):

      SAP Sales and Service Core test

    Congratulations! You’ve successfully created an end-to-end integration scenario leveraging low-code/no-code capabilities from the SAP Integration Suite and SAP Build Apps, for integrating SAP and third-party solutions.
