Before you begin
These instructions explain how to add Scalapay to your existing API-only integration. Accept payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.
Before starting your Scalapay integration:
- Make sure that you have set up your back end implementation.
- Add Scalapay in your test Customer Area.

Handle the redirect
-
To complete the payment, redirect the shopper to the
action.url
returned in the /payments response, taking into account the following recommendations:-
When using the HTTP GET method:
For security reasons, when showing the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView. -
Redirection for mobile integrations:
For mobile integrations, we strongly recommended that you redirect the shopper to the default browser of their device. Redirecting to the default browser ensures the best compatibility, handling of multi-factor authentication, app-to-app redirection, and error handling.
-
-
After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
details
: object that contains the URL-decodedredirectResult
returned when the shopper was redirected back to your site.
-
In the response note the following:
resultCode
: use this to present the result to your shopper.pspReference
: our unique identifier for the transaction.
Show the payment result
Use the resultCode that you received in the /payments/details response to show your shopper the payment result.
The resultCode
values you can receive for Scalapay are:
resultCode | Description | Action to take |
---|---|---|
Authorised | The payment was successful. | Inform the shopper that the payment has been successful. Ship the goods after you successfully capture the payment. |
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. | 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 fails 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 is successful and proceed with the order. |
Capture the payment
Make sure that the payment is captured successfully before you ship the goods.
Depending on your capture settings, Scalapay payments are captured manually or automatically, with or without a delay.

Use the test cards for the test scenarios that are specified on the Scalapay website.
Check the status of Scalapay test payments in your Customer Area > Transactions > Payments.
