Create a seamless flow with the Payments API

In The Payment API section we explain how the Payments API can be leveraged to create a payment flow.

Checkout integration

Let Rootline handle the payment method selection. You initiate the payment by simply sending a payment request with below details.

{
  "account_id": "acc_12347Sifdo36cdycbsw4Pum",
  "amount": {
    "currency": "EUR",
    "quantity": "20.00"
  },
  "reference": "test_reference",
  "statement_descriptor":"Bank statement text",
  "return_url":"https://www.my_return_url.com"
}

The API will return a next_action object with a checkout_url. This url leads your customer to the Rootline checkout page, where they can select their payment method and further payment details.

{
    "payment_id": "pmt_UXRFkdU6kdAtO6ceGdxmW",
    "created_at": "2023-09-12T08:22:25.864452Z",
    "account_id": "acc_12347Sifdo36cdycbsw4Pum",
    "reference": "test_reference",
    "amount": {
        "currency": "EUR",
        "quantity": "20.00"
    },
    "checkout_status": "open",
    "authorizations": [],
    "authentications": [],
    "next_action": {
        "checkout_url": "http://checkout.rootline.com/payments/pmt_UXRFkdU6kdAtO6ceGdxmW/checkout"
    },
      "statement_descriptor":"Bank statement text",  
    "return_url": "https://www.my_return_url.com"
}

Forwarding your customer through the checkout url

Request a redirect to your customer's bank by calling (/GET) the checkout_url that Rootline provides.

Seamless redirect from your website to WeChat Pay

The custom integration allows you to redirect a customer from your page to WeChat Pay, without visibly interacting with Rootline's checkout pages. Payment method selection can be done in your own page. In addition to the /POST request above, to indicate that this is an WeChat Pay payment, provide wechatpay as the value for the payment_rails.payment_method field:

{
  "account_id": "acc_12347Sifdo36cdycbsw4Pum",
  "amount": {
    "currency": "EUR",
    "quantity": "20.00"
  },
  "payment_rails":{
    "payment_method":"wechatpay"
  },
  "reference": "test_reference",
  "description":"Test description",
  "statement_descriptor":"Bank statement text",
  "return_url":"https://www.my_return_url.com"
}

Use the checkout redirect url for a seamless redirect to WeChat Pay. After completion of the payment, your customer will be redirected back to the return url that you provided.

    "reference": "test_reference",
    "amount": {
        "currency": "EUR",
        "quantity": "20.00"
    },
    "payment_rails":{
        "payment_method":"wechatpay"
    },
    "checkout_status": "open",
