Parameters

PaymentInfo

| Field | Type | Description | | ----------- | ----------- | ----------- | | apiKey *required | string | Merchant's api key, issued by Noda | | amount *required | number | Payment amount | | currency *required | string | Payment currency in ISO_4217 format. Currently accepted: {GBP, EUR} | | returnUrl *required | string | After the payment completed, customer will be redirected into this Url | | paymentId *required | string | Order identificator in merchant's system | | webhookUrl | string | URL where the Noda will send hooks about the payment status changes | | shopId | string | Merchant's shop identificator, issued by Noda. If you have more than one online shop, this parameter helps to analyse the payments afterwards | | description | string | Short order description for the customer | | customerId | string | End-customer Id in merchant's system.

That parameter can be used to find a best button appearance for the particular customer. | | iin | integer | IIN (first six digits) of the end-customers credit card used earlier at the merchant's checkout. This parameter helps to define end-customer Bank and propose to pay with that bank. | | ipAddress | string | End-customer IP Address. That parameter can be used to detect a customer's country (for example, for EUR payments - Spain, Germany, France etc.) | | result | function | Payment completion callback function implemented by merchant | | onHistory | function | Billing information changes callback function implemented by merchant | | disabled | boolean | Noda Button component state | | replaceWindow | boolean | Will replace the current window with bank page after bank selection | | customerEmail *depricated (use email field instead) | string | End-customer e-mail.

Environment

| Field | Type | Description | | ----------- | ----------- | ----------- | | env | string | App environments, for develop and production. Currently accepted: {PRODUCTION, DEVELOPMENT}. Default: {PRODUCTION} |

Methods

| Method | Parameters | Description | | ----------- | ----------- | ----------- | | render | HTMLElement, Enviroment | Render method inject button in DOM node, where root is an element id. Need only once | | update | PaymentInfo, Country | Update method changes button view, state and payment scenario | | unmount | HTMLElement | Unmount method removes button from the selected DOM node |

Security

Remember to use valid api token for apiKey field.

How to obtain the keys?

Sandbox: use 24d0034-5a83-47d5-afa0-cca47298c516 for DEVELOPMENT environment. Live: use 808e683e-9383-4717-8148-02e74b63b1f8 for testing purposes.

Please consider, that this is a real payment routing which is set up to charity organisations complete the onboarding at ui.noda.live/hub to get your production keys

Creating a Payment

In order to initiate payment, pass the payment parameters into update method.

Payment UX

Depending on the additional parameters passed, payment UX will be rather country-oriented (with the bank selection at the first step) or bank-oriented (with the particular bank pre-selected). Please switch the "Purchase scenarios" at ui.noda.live/demo in order to overview the different behavior.

If you've used some additional parameters (for example - IP, IIN, CustomerID and so on) previosly, for the same purchase, we highly recommend pass the same additional parameters, in order to keep the consistent UX for the customers.

Payment Result parameters

| Parameter | Description | | ----------- | ----------- | | id | Payment identificator in Noda system | | status | Payment status: {Done, Failed} | | signature | Signature: sha256(id+status+signatureKey) |

Payment Result handling

You can receive payment result with the following options:

parameters in returnUrl After the payment completed, customer will be redirected into returnUrl with the Payment Result parameters in query string:

https://{domain}?id=63c507d9-4f19-46d0-ac37-5b7d4f6fe040&status=Done&signature=6ec13bda02080a4006223c1ba9d8fa97e2de0a1ca782d95d63f4b69789117cc6

receive a hook into webhookUrl If you passed webhookUrl earlier, you will receive the hook as POST request with the Payment Result parameters as JSON body (example):

{
    id: "63c507d9-4f19-46d0-ac37-5b7d4f6fe040",
    status: "Done",
    signature: "6ec13bda02080a4006223c1ba9d8fa97e2de0a1ca782d95d63f4b69789117cc6"
}

For the returnUrl and webhookUrl handling methods, make sure to implement the proper payment control procedures

Control procedures

If you're using returnUrl and/or webhookUrl for the results handling, it is mandatory to implement a simple control procedure in order to prevent fraudulent behaviour. After receiving the results you will need to do the following:

Verify the payment signature parameter The signature can be verified with the following algorythm:

signature == sha256(id+status+signatureKey)

Check the duplicates of signatures

You will need to make sure the payment result belongs to the concrete order you are about to proceed. Intruders can not create a valid Signature unless they know your SignatureKey. However, they can intercept the result message and then re-use its Signature. In order to prevent this action, you will need to implemenent anti-duplication control algorythm. For example, you can compare the paymentId of the current order and in the payment result.

Api usage
