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.

How to install

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. From the Shopify app store, install the MultiSafepay Payments app .
  3. Enter your site API key, and specify whether it is a live or test key.
  4. Click Save and continue (might take a few seconds).
    A pop up or new tab opens.
  5. Scroll down and click Activate MultiSafepay payments.
  6. Under Admin > Settings > Payments > Alternative payment methods, check that the app has been successfully added.
  7. In your Shopify checkout, test the MultiSafepay payments gateway.
    ❗️ If using a test API key, make sure you also enable Test mode.
  8. For existing merchants, under Admin > Settings > Payments > Third-party payment providers, disable the deprecated individual MultiSafepay payment method gateways.
  9. Once testing is complete, disable password protection again.

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.
