To integrate Vipps payments into your C# operation, you'll need to use the Vipps API. Below is a simplified example of how you can initiate a payment request using C# and the Vipps API. This example demonstrates how to create a Vipps payment request and obtain a payment URL:

                                
                                      
    public string GeneratePaymentRequest()
    {
      string clientId = "your_client_id";
      string clientSecret = "your_client_secret";

      string baseUrl = "https://api.vipps.no";
      string paymentRequestEndpoint = "/ecomm/v2/payments";

      var paymentRequest = new
      {
          merchantInfo = new
          {
              merchantSerialNumber = "your_merchant_serial_number",
          },
          customerInfo = new
          {
              mobileNumber = "customer_mobile_number",
          },
          transaction = new
          {
              orderId = "your_order_id",
              amount = 100, // The payment amount in cents
          },
      };
      string jsonPaymentRequest = Newtonsoft.Json.JsonConvert.SerializeObject(paymentRequest);

      using (var client = new HttpClient())
      {
          client.BaseAddress = new Uri(baseUrl);
          client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

          client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes($"{clientId}:{clientSecret}"));

          HttpResponseMessage response = await client.PostAsync(paymentRequestEndpoint, new StringContent(jsonPaymentRequest, System.Text.Encoding.UTF8, "application/json"));

          if (response.IsSuccessStatusCode)
          {
              string responseContent = await response.Content.ReadAsStringAsync();
              Console.WriteLine("Payment request successful.");
              return responseContent;
          }
          else
          {
              return "Payment request failed.";
          }
      }
  }

        public string CreateSubscription()
        {
        string clientId = "your_client_id";
        string clientSecret = "your_client_secret";
        string baseUrl = "https://api.vipps.no";
        string subscriptionEndpoint = "/recurring/v1/subscriptions";

        var subscriptionRequest = new
        {
            merchantInfo = new
            {
                merchantSerialNumber = "your_merchant_serial_number",
            },
            customerInfo = new
            {
                mobileNumber = "customer_mobile_number",

            },
        };

        string jsonSubscriptionRequest = Newtonsoft.Json.JsonConvert.SerializeObject(subscriptionRequest);

        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(baseUrl);

            if (response.IsSuccessStatusCode)
            {
                string responseContent = await response.Content.ReadAsStringAsync();
                Console.WriteLine("Subscription creation successful.");
                return responseContent;
            }
            else
            {
                return "Subscription creation failed.";
            }
        }
    }

                                
                            

Dynamic Recurring Payment Integration with Vipps (C# Code)

Dynamic Recreating payments allow your SaaS operation to bill guests different quantities grounded on operation or variable subscription plans. To enable dynamic recurring payments with Vipps, you can follow these steps:

• User Approval: Before enabling dynamic recurring payments, you can use Vipps to send a small transaction (e.g., NOK 20 to 30) to the user's account. The user will receive a notification asking for approval. If the user agrees, you can proceed with dynamic recurring payments.
• API Integration: Integrate Vipps' API into your SaaS operation to manage dynamic recreating payments. The API will handle the billing and keep track of varying payment quantities.
• Customization: Customize your application to calculate the dynamic amounts based on usage or subscription changes. Insure that your operation communicates effectively with Vipps to initiate the payments.

Dynamic recurring payments allow customers to set up recurring payments for varying amounts and schedules.

                                
                                    
    public string CreateDynamicRecurring()
    {
        string clientId = "your_client_id";
        string clientSecret = "your_client_secret";
        string baseUrl = "https://api.vipps.no";
        string paymentLinkEndpoint = "/ecomm/v2/payments";

        var dynamicRecurringRequest = new
        {
            merchantInfo = new
            {
                merchantSerialNumber = "your_merchant_serial_number",
            },
            transaction = new
            {
                orderId = "your_order_id",
                amount = 0, // The initial payment amount (can be zero for dynamic recurring),
                operation = "INITIATE_PAYMENT",
                recurring = new
                {
                    frequency = "WEEKLY", // Set the desired payment frequency
                    interval = 1, // Set the interval
                    endDate = "yyyy-MM-ddTHH:mm:ssZ", // Set the end date for recurring payments
                },
            },
        };
        string jsonDynamicRecurringRequest = Newtonsoft.Json.JsonConvert.SerializeObject(dynamicRecurringRequest);
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(baseUrl);
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes($"{clientId}:{clientSecret}"));
            HttpResponseMessage response = await client.PostAsync(paymentLinkEndpoint, new StringContent(jsonDynamicRecurringRequest, System.Text.Encoding.UTF8, "application/json"));

            if (response.IsSuccessStatusCode)
            {
                string responseContent = await response.Content.ReadAsStringAsync();
                Console.WriteLine("Dynamic recurring payment link created successfully.");
        return responseContent;
            }
            else
            {
                return "Dynamic recurring payment link creation failed.";
            }
        }
    }

                                
                            

Challenges in Dynamic Recurring Payments

While dynamic recurring payments offer flexibility, there are challenges to consider:

• User Approval: Not all users may approve the initial small transaction, preventing you from enabling dynamic recurring payments for them. You may need to implement alternative billing methods for these users.
• Billing Accuracy: Icing the delicacy of billing for dynamic recreating payments can be complex. You must maintain precise records of usage and subscription changes to avoid billing errors.
• Communication: Effective communication between your SaaS operation and Vipps is pivotal. Any breakdown in communication can lead to issues with billing and user experience.

After receiving the response, you can save the response and extract the paymentLink to send to the user. When the user clicks the link in a web browser, they will be prompted to enter their credentials and proceed with the payment. However, if the user clicks the link on a mobile device, the behavior will depend on whether the Vipps app is installed:

• Vipps App Installed: If the Vipps app is installed on the user's mobile device, clicking the link will trigger the app to open. The stoner will be notified within the Vipps app, and they can give their credentials within the app to do with the payment.
• Vipps App Not Installed: However, clicking the link will affect in redirection to a web cybersurfer, If the Vipps app isn't installed on the stoner's mobile device. In the web browser, the user will be prompted to enter their credentials and complete the payment.
