Integrate SDK on application side

1. Design the user interface for the subscription catalog, viewing information about the user’s current subscription, and other pages in your application.
2. Implement purchase and management of a user’s subscription using SDK methods.

Subscription purchase scenario

1. The application requests a list of available plans using the following SDK methods:
   • getSubscriptionPublicPlans — returns a list of plans available to unauthorized users.
   • getSubscriptionPlans — returns a list of plans available to authorized users.

2. The application displays subscription plans to the user.
3. The user selects a plan and proceeds to the payment stage.
4. The application receives the URL to open the payment interface using the getSubscriptionPurchaseUrl method.
5. The application opens the received URL in a browser or WebView.
6. The user pays for a subscription.

Subscription management scenario

1. The application requests a list of the user’s subscriptions using the getSubscriptions method.
2. The application requests detailed information about each user’s subscription using the getSubscriptionDetails method (optional).
3. The application displays a list of subscriptions to the user.
4. The user selects a subscription and the action he wants to perform — cancel, renew, open a web page to manage subscriptions.
5. The application calls one of the following methods to handle the action:

1. • cancelSubscription — to cancel the selected subscription.
   • getSubscriptionRenewalUrl — to get the URL of the renewal interface for the selected subscription.
   • getSubscriptionManagementUrl — to get the URL of the management interface for the selected subscription.

6. The application opens the received URL in a browser or WebView.
7. The user performs an action on a subscription.
