  • Step 2
    1. Access Tokens through your bot’s Settings.

      “Generate OAuth client”
    2. Click Generate to create the OAuth client Runtime API.

    3. Choose Client Credentials.

      Choose client authentication type
    4. Close the confirmation dialog.

      Confirmation dialog
    5. Copy the generated Auth URL, Client ID and Client Secret to reuse later.

  • Step 3
    1. Click on Mobile Connectivity in your application definition.

      “Navigate to Mobile Connectivity feature”
    2. Click the + button to start the destination create wizard.

      Create a new destination
    3. In Basic Info enter the required Destination Name and URL.

      Field Value
      Destination Name CAI

      Note: Outside of this tutorial, you are free to choose any name for your destination. The URL is different and tenant-specific if you use SAP Conversational AI Enterprise Edition but the suffix /public/api is always needed.

      Click Next.

    4. Click Next on Custom Headers.

    5. Click Next on Annotations.

    6. In Destination Configuration select OAuth2 Client Credentials for SSO mechanism.

      Note: Destination and SSO Mechanism depend on the edition type of SAP Conversational AI as well as the deployment scenario. Read Enterprise Configuration guide to understand when to use other SSO mechanism types.

      Enter the required Token Service URL, Client ID and Client Secret by reusing the information from Step 2.

      Field Value
      SSO Mechanism OAuth2 Client Credentials
      Token Service URL
      Client ID Your bot's Client ID (generated in Step 2)
      Client Secret Your bot's Client Secret (generated in Step 2)
      Enter details

      Note: Token Service URL is named Auth URL in SAP Conversational AI.

      Click Next.

    7. Click Finish.

    8. Click Ping to test if the destination can reach its target.

      Ping the target system to verify that destination works

    What is the SSO mechanism used for the destination?

  • Step 4
    1. Open your Xcode project.

    2. In Xcode menu select File > Add Packages… which opens a modal dialog.

    3. Paste the following URL into the search field:

      Add Package
    4. Click “Add Package”.

    5. Select Package Product SAPCAI-requiresToEmbedXCFrameworks.

    6. Click “Add Package”.

    Note: You chose Package Product SAPCAI-requiresToEmbedXCFrameworks because your app already embeds SAPCommon and SAPFoundation binary frameworks. You would select package product SAPCAI if you did not already embed binary frameworks from SAP BTP SDK for iOS.

    What are the Package Products offered by SAP Conversational AI SDK for iOS?

  • Step 5

    It is finally time to use APIs from the SAP Conversational AI SDK for iOS. Let’s create a new file named AssistantViewManager.swift.

    Copy & paste the following code into the newly created file.

    import SAPCAI
    import SAPFoundation
    import SAPFioriFlows
    import SwiftUI
    class AssistantViewManager {
        static let shared = AssistantViewManager()
        var viewModel: MessagingViewModel?
        var dataPublisher: CAIConversation?
        func createDemoBotAssistantView() -> UIViewController {
            let serviceConfig = CAIServiceConfig(
                urlSession: OnboardingSessionManager.shared.onboardingSession!.sapURLSession,
                host: OnboardingSessionManager.shared.onboardingSession!.settingsParameters!.backendURL.appendingPathComponent("CAI") // name of your destination created in Step 3
            let caiChannel = CAIChannel(
                id: "Replace with Channel ID from Step 1",
                token: "Replace with Token from Step 1",
                slug: "Replace with Name from Step 1")
            self.dataPublisher = CAIConversation(
                config: serviceConfig,
                channel: caiChannel,
                messageDelivery: PollMessageDelivery(channelToken: caiChannel.token, channelId:, serviceConfig: serviceConfig))
            self.viewModel = MessagingViewModel(publisher: dataPublisher!)
            return UIHostingController(rootView: AssistantView()
                                    .navigationBarTitle(Text("Chat"), displayMode: .inline)
        func cleanup() {
            viewModel = nil
            dataPublisher = nil

    You created class AssistantViewManager which is accessible as a singleton through its shared property.

    Some explanations about the code:

    • You imported the SAPCAI module because this is the module of the added Swift Package.
    • You imported the SwiftUI framework because you will use SwiftUI view(s) provided by the added Swift Package.
    • You imported SAPFoundation and SAPFioriFlows because you are reusing its classes, especially SAPURLSession which is fully configured to make network requests towards your SAP Mobile Service account once the user onboarded in the app.
    • You initialized CAIServiceConfig so that SAP Conversational SDK for iOS can make network requests to the destination in SAP Mobile Services created in Step 3.
    • You need to replace the initializer parameters of CAIChannel with the actual values from Step 1 !
    • You used AssistantView which is the main reusable SwiftUI component provided by the added Swift Package. The SwiftUI view will render messages of your user’s conversation with your chatbot.
    • You are wrapping AssistantView with UIHostingController to use it in your UIKit-based application.

    Next, in ESPMContainerCollectionsViewController.swift add the following code at the end of function viewDidLoad.

    self.navigationItem.setRightBarButton(UIBarButtonItem(barButtonSystemItem: .compose, target: self, action: #selector(self.startConversation)), animated: true)

    This code adds a right bar button to invoke a function startConversation which you will create now. Add the following functions to class ESPMContainerCollectionsViewController.

    // MARK: - SAPCAI integration
    @objc func startConversation() {
        present(vc: AssistantViewManager.shared.createDemoBotAssistantView())
    func present(vc: UIViewController) {
        let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
        let rightNavigationController = mainStoryBoard.instantiateViewController(withIdentifier: "RightNavigationController") as! UINavigationController
        rightNavigationController.viewControllers = [vc]
        self.splitViewController?.showDetailViewController(rightNavigationController, sender: nil)

    Add the following code at the end of function viewDidAppear(_ animated: Bool).


    That code ensures that polling of conversation updates will stop once the user navigates away from the AssistantView.

    Which is the reusable SwiftUI view, provided by the SAP Conversational AI SDK for iOS, to render a conversation natively?
