    Switching to the new SendPol Wix app

    We have completely rebuilt the SendPol app for Wix. Version 2 is an all-new app with a faster connection, a clearer dashboard and more control. On this page you will learn what changes and how to switch in just a few minutes.

    Free to switch · No interruption in principle · Switch before 1 August 2026

    Important: the old app goes offline on 1 August 2026

    The legacy app (v1) is being phased out and goes offline on 1 August 2026. Switch to version 2 before that date to keep your Peppol invoicing uninterrupted.

    Why an all-new app?

    The first version of our Wix app worked with webhooks and a manual API key that you had to manage yourself. Based on feedback from our users, we rebuilt the app from scratch.

    Version 2 is not an update of the old app, but a separate, new app. Onboarding, KYC verification and invoicing now run directly through Wix, and you connect SendPol via a secure OAuth authorization instead of an API key. That is why you need to switch once: install the new app, complete the OAuth connection and only then remove the old app.

    Migration guide in 4 steps

    Follow these steps to switch from version 1 to version 2. Complete them in one go and there is in principle no interruption.

    1. 1

      Install the new SendPol app (v2)

      Install the new app in your Wix admin. This is a separate app alongside your old version.

    2. 2

      Configure v2 via OAuth

      Complete the OAuth connection to securely connect SendPol to your store. No API key needed anymore.

    3. 3

      Check the connection status

      Make sure the connection status shows "connected" and that v2 works correctly.

    4. 4

      Only then remove the old app (v1)

      Is everything working in the new app? Only then remove the old SendPol app from your Wix admin.

    Save your invoice history before removing v1

    Your invoice history is not transferred to v2. So export or save important documents before you remove the old app.
