Requirements

Select the server-side flow that your integration uses:

Show MOLPay online banking in your payment form

Include MOLPay in the list of available payment methods.

Specify in your /paymentMethods request:
- countryCode: Array.
- amount.currency: Array.
- channel: Specify iOS.
Decode the /paymentMethods response with the PaymentMethods structure.
```
let paymentMethods = try JSONDecoder().decode(PaymentMethods.self, from: paymentMethodsResponse)
```
Find paymentMethods.type Array and put it into an object. For example, molpayPaymentMethod.
Create an instance of APIContext with the following parameters:

Parameter name Required Description

clientKey Your client key.

environment Use test. When you are ready to accept live payments, change the value to one of our live environments.

Initialize the MOLPay Component:

let molpayComponent = MolPayComponent(paymentMethod: molpayPaymentMethod, apiContext: apiContext)
molpayComponent.delegate = self
// In this example, the Pay button will show 10 EUR.
// The value is in minor units. Change the currencyCode to the currency for the MOLPay Component.
molpayComponent.payment = Payment(amount: Amount(value: 1000,
                                                              currencyCode: "EUR"))
present(molpayComponent.viewController, animated: true)

Make a payment

When the shopper proceeds to pay, the Component invokes the didSubmit method containing the data.paymentMethod from the PaymentComponentDelegate.

Pass the data.paymentMethod to your server.
From your server, make a /payments request, specifying:
- paymentMethod.type: The data.paymentMethod from your client app.

In the  /payments response, note the `action` object. This contains the information needed to redirect the shopper.

<div data-component-wrapper="code-sample">
<code-sample
    :title="'/payments response'"
    :id="''"
    :code-data="[{&quot;language&quot;:&quot;json&quot;,&quot;tabTitle&quot;:&quot;&quot;,&quot;content&quot;:&quot;{\n   \&quot;resultCode\&quot;:\&quot;RedirectShopper\&quot;,\n   \&quot;action\&quot;:{\n      \&quot;paymentMethodType\&quot;:\&quot;molpay\&quot;,\n      \&quot;method\&quot;:\&quot;GET\&quot;,\n      \&quot;url\&quot;:\&quot;https:\/\/checkoutshopper-test.adyen.com\/checkoutshopper\/checkoutPaymentRedirect?redirectData=...\&quot;,\n      \&quot;type\&quot;:\&quot;redirect\&quot;\n   }\n}&quot;}]"
    :enable-copy-link-to-code-block="true"
    :code-sample-card-size="'fullsize'"
></code-sample>

Pass the action object to your client app. You need this to initialize the Redirect Component.

Handle the redirect

Use the Redirect Component to redirect the shopper to the issuing bank's app or website.
After the shopper returns to your app, make a POST /payments/details request from your server and provide the data from the didProvide method from your client app.

You receive a response containing:

resultCode: Use this to present the result to your shopper.
pspReference: Our unique identifier for the transaction.

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for MOLPay online banking are:

resultCode	Description	Action to take
Authorised	The payment was successful.	Inform the shopper that the payment has been successful. You will receive the funds in 2-3 days.
Cancelled	The shopper cancelled the payment while on their bank's website.	Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error	There was an error when the payment was being processed.	Inform the shopper that there was an error processing their payment. You'll receive a `refusalReason` in the same response, indicating the cause of the error.
Pending or Received	The shopper has completed the payment but the final result is not yet known. It may take minutes or hours for the MOLPay online banking payments network to confirm this.	Inform the shopper that you have received their order, and are waiting for the payment to be completed. You will receive the final result of the payment in an AUTHORISATION webhook.
Refused	The payment was refused by the shopper's bank.	Ask the shopper to try the payment again using a different payment method.

If the shopper failed to return to your website or app, wait for webhooks to know the outcome of the payment:

eventCode	success field	Description	Action to take
AUTHORISATION	false	The transaction failed.	Cancel the order and inform the shopper that the payment failed.
AUTHORISATION	true	The shopper successfully completed the payment.	Inform the shopper that the payment has been successful and proceed with the order.

Test and go live

Using any issuer ID that is available for the MOLPay eBanking Component for the respective country/region, make MOLPay online banking test payments to test the different payment results.

Check the status of the MOLPay test payments in your Customer Area > Transactions > Payments.

Before you can accept live MOLPay payments, you need to submit a request for MOLPay in your live Customer Area.
