Overview

There are four steps to creating a complete checkout:

1. Create a Product
2. Create a Price
3. Create a Checkout
4. Jump to the cashier to complete the payment

1. Create a Product

Products and prices are core resources for many WooshPay integrations. Products define what your business offers, whether that’s goods or services.

Request

{
    "name":"example product",
    "active":true,
    "description":"some description",
    "metadata":{
        "key1":"value1",
        "key3":"value3"
    },
    "url":"www.example.com"
}

Response

{
    "id": "prod_1554351292598452224",
    "object": "product",
    "created": 1665642282000,
    "active": true,
    "description": "some description",
    "metadata": {
        "key1": "value1",
        "key2": "value2"
    },
    "name": "example product",
    "livemode": false,
    "url": "www.example.com",
    "updated": 1665642282000,
    "images": null
}

2. Create a Price

Prices define how much and how often to charge for products. You can create single or multiple prices for a product.

Request 1：Directly bind the exsisted product

{
    "currency":"GBP",
    "product":"prod_1554351292598452224",
    "unit_amount":5,
    "active":true,
    "metadata":{
        "key1":"value1",
        "key2":"value2"
    },
    "nickname":"some nickname",
    "product_data":null,
    "lookup_key":"test_lookup_key"
}

Request 2：Create a new product while create a price

{
    "currency":"GBP",
    "product":null,
    "unit_amount":5,
    "active":true,
    "metadata":{
        "key1":"value1",
        "key2":"value2"
    },
    "nickname":"fengli",
    "product_data":{
        "id":null,
        "name":"example product",
        "active":true,
        "description":"very delicious",
        "metadata":{
            "key1":"value1",
            "key2":"value2"
        },
        "url":"www.example.com"
    },
    "billing_scheme":"testscheme",
    "lookup_key":"test_lookup_key"
}

    "object":"price",
    "created":1659429194000,
    "active":true,
    "currency":"GBP",
    "metadata":{
        "key1":"value1",
        "key2":"value2"
    },
    "nickname":"some nickname",
    "product":{
        "id":"prod_1554351292598452224",

    "livemode":false,
    "unit_amount":5,
    "billing_scheme":"per_unit",
    "lookup_key":"test_lookup_key"
}

3. Create Checkout

A Checkout Session is the programmatic representation of what your customer sees when they’re redirected to the payment form. You can configure it with options such as:

• line_items to charge
• currencies to use

You also need to specify:

• A success_url, a page on your website to redirect your customer after they complete the payment.
• A cancel_url, a page on your website to redirect your customer if they click on your logo in Checkout.

Note: Checkout Sessions expire 24 hours after creation.

Request

{
    "cancel_url":"www.example.com",
    "mode":"payment",
    "success_url":"www.wooshpay.com",
    "line_items":[
        {
            "price_data":{
                "currency":"GBP",

                "nickname":"fengli",
