Implement Plan Changes

This guide explains how to handle subscription plan changes (upgrades/downgrades) in your application.

Customer Portal Method

The simplest way to handle plan changes is through Stripe's Customer Portal:

await iaptic.redirectToCustomerPortal({
  id: 'sub_xyz',
  accessKey: 'ak_123',
  returnUrl: 'https://example.com/account'
});

This provides a full-featured portal where customers can:

  • Change plans
  • Update payment methods
  • View invoices
  • Manage billing

Direct Plan Change

For more control, use the direct plan change endpoint:

const response = await iaptic.changePlan({
  id: 'sub_xyz',
  accessKey: 'ak_123',
  offerId: 'stripe:prod_xyz#price_xyz',
  successUrl: 'https://example.com/success',
  cancelUrl: 'https://example.com/cancel'
});

// Handle the updated subscription
console.log('New plan:', response.purchase);
