Accept a PromptPay payment

A Checkout Session must satisfy all of the following conditions to support PromptPay payments:

• Prices for all line items must be in the same currency. If you have line items in different currencies, create separate Checkout Sessions for each currency.
• You can only use one-time line items (PromptPay Checkout Sessions don’t support recurring subscription plans).

This guides you through enabling PromptPay and shows the differences between accepting a card payment and using PromptPay.

Enable PromptPay as a payment method

When creating a new Checkout Session, you need to:

1. Add promptpay to the list of payment_method_types
2. Make sure all your line_items use the same currency

Stripe.api_key = 
'sk_test_4eC39HqLyjWDarjtT1zdp7dc'
Stripe::Checkout::Session.create({
  mode: 'payment',
  payment_method_types: ['card'],
  payment_method_types: ['promptpay'],

  # or you can take multiple payment methods with
  # payment_method_types: ['card', 'promptpay', ...]
  line_items: [{
    price_data: {
      currency: 'thb',
      product_data: {
        name: 'เสื้อยืด',
      },
      unit_amount: 1000,
    },
    quantity: 1,
  }],
  success_url: 'https://example.com/success',
  cancel_url: 'https://example.com/cancel',
})
