Technical manual for MultiSafepay's free app.


Urgent action required!

As of July 31, 2022, the deprecated version of the app will no longer be supported. Payments will not be processed.
Migrate to our updated app as soon as possible.
The new app leverages a single, powerful gateway for a faster, safer integration.


You will need a MultiSafepay account.


To install or migrate, follow these steps:

  1. For increased security and stability, wait for off-peak hours and temporarily enable password protection for your webshop.
  2. Check that the payment methods you want to use in Shopify are activated for your MultiSafepay account.
  3. From the Shopify app store, install the MultiSafepay payments app .
  4. Under Settings:
    • Website API key: Enter your site API key.
    • Environment: Set whether it is a live or test key.
  5. Click Save and continue (might take a few seconds).
    You are redirected to Settings > Payments.
  6. For each payment method you want to activate, on the app page:
    • If Shopify has not reviewed the payment method yet, click Install unlisted app.
    • Select the payment method checkbox.
    • Under Test mode, select the Enable test mode checkbox.
    • Click Activate .
      If the payment method is not activated for your MultiSafepay account, an error appears.
  7. Activate the method for your MultiSafepay account, and then in Shopify, click Retry.

✅   Tip! We recommend first testing each payment method before setting your live API key.

Abandoned checkouts

MultiSafepay's Second Chance feature is not supported because Shopify offers a similar native service.

See Shopify – Recovering abandoned checkouts .


If a customer cancels a payment to use another payment method instead, they must complete payment within 2 hours to avoid errors.


The app is unavailable in Norway and Finland.

Payments are processed in the webshop's default currency only.
