Tenant-Edition Subscription

SaaS module implements subscribing to Editions for Tenants using Payment module. To enable it, project must contain Volo.Saas and Volo.Payment modules and these modules must be configured as shown below.

Configuration

Firstly, Payment module must be configured properly:

  • Install Volo.Payment module.
  abp add-module Volo.Payment

Or you can install via using ABP Suite.

  • Configure Saas module to use Payment.
  Configure(options =>
{
options.IsPaymentSupported = true;
});

Usage

SaaS module doesn't contain a public facing list page for listing editions for new customers/tenants to subscribe. First, you need to create such a page in your application. Then, when a new customer/tenant selects one of those Editions, you can create a subscription and redirect user to payment module as shown below.

  • Inject ISubscriptionAppService to create a subscription for a edition:
  public class IndexModel : PageModel
{
protected ISubscriptionAppService SubscriptionAppService { get; }

protected ICurrentTenant CurrentTenant { get; }

public IndexModel(
ISubscriptionAppService subscriptionAppService,
ICurrentTenant currentTenant)
{
SubscriptionAppService = subscriptionAppService;
CurrentTenant = currentTenant;
}

public async Task OnPostAsync(Guid editionId)
{
var paymentRequest = await SubscriptionAppService.CreateSubscriptionAsync(editionId, CurrentTenant.GetId());

return LocalRedirectPreserveMethod("/Payment/GatewaySelection?paymentRequestId=" + paymentRequest.Id);
}
}

When the payment is completed successfully, the tenant and edition relation will be updated according to subscription status. Make sure Payment Gateway Web Hooks are configured properly.

After all, payment module will redirect user to the callbackUrl if configured in payment configuration with a paymentRequestId parameter. In this page, you can check the status of the payment request and show a success message to the user when the payment status is confirmed. Since the payment confirmation is asynchronous, you need to check the payment status repeatedly until it is confirmed.

  • Tenants: Tenant management page.
