# Supported Use Cases

All flows described below work with both Payment Session interfaces either Payment Link or Xendit Components.

Each flow represents a different checkout intent, such as collecting a one-time payment, saving a payment method, or doing both in a single interaction.

You choose the flow by setting the appropriate `session_type` when creating a Payment Session.

## One-Time Payment (`PAY`)

This mode is used for single payment where customer is present, choose payment method and pays immediately. No payment method is stored after the transaction is completed.

**User Journey**

1. **Checkout**: Customer clicks “Buy Now” on your site
2. **Selection**: Customer is presented with available payment methods
3. **Payment**: Customer process the required actions to authorize the payment
4. **Completion**: Customer is redirected back to your site page

It is best for business with one off transaction (e.g., one-off purchases, e-commerce checkouts, event tickets or digital goods)

## Save Payment Method (`SAVE`)

Use this mode when you want to securely save a customer’s payment method (tokenization) **without** charging them immediately. This is often done during sign-up or inside a “My Account” settings page in your application.

**User Journey**

1. **Setup**: Customer clicks “Add Payment Method” in their profile
2. **Verification**: Customer enter card/account details and proceed the verification process based on the payment method
3. **Tokenization**: Xendit securely stores the payment method details and returns `payment_token_id` to you
4. **Ready**: Customer is ready to make future purchases later

It is best for building a frictionless subscription onboarding, auto-debit setup, or saving cards for faster future checkout.

## Pay and Save (`PAY`)*

This flow uses the `PAY`****session type and allows you to optionally or mandatorily save the customer’s payment method during a payment - the behavior is controlled by the `allow_save_payment_method` parameter when creating a Payment Session.

**User Journey**

1. **Transaction:** Customer pays for their first order.
2. **Consent:** A checkbox to optionally save the payment method, or a forced pay and save depending on your use case
  1. Find more details on these differences in [here](/v1/docs/pay-and-save-2#how-to-integrate)
3. **Execution:** Xendit processes the payment **and** generates payment token simultaneously.
4. **Outcome:** The current order is paid, and Xendit securely stores the payment method details and return `payment_token_id` to you. You can use the `payment_token_id` for subsequent transaction either Merchant-initiated or Customer-initiated flow using [Payment API integration](/v1/docs/pay-with-tokens).
