Setting up OneSignal Push Notifications

Before you begin​

Make sure you have:

  • A OneSignal App already created for your store and access to its dashboard.
  • Reactiv Sales Channel installed in your Shopify store.
  • Access to both Shopify Admin and OneSignal with the correct credentials.

1. Copy your OneSignal credentials​

  • Sign in to your OneSignal dashboard and select the app you created for your store.
  • In the left sidebar, click Settings → Keys & IDs.
  • Copy these two values:
    • App ID – shown at the top of the page.
    • REST API Key – click Add API Key, name it, then click Create and Copy.


2. Connect OneSignal inside Reactiv​

  • Log in to your Shopify admin dashboard.
  • In the left-hand sidebar, scroll to the Sales Channels section.
  • Click Reactiv – Mobile App Builder, then select App Studio.
  • From the left navigation panel under App Studio, click Integrations.
  • Scroll through the list of integrations until you find OneSignal, click Connect.
  • Paste the App ID and REST API Key you copied from OneSignal, then click Connect.


  • In the Reactiv sidebar, click Workflows.
  • Click Settings then Integration Settings.
  • Paste the OneSignal App ID in the OneSignal field.
  • Click Publish to activate the workflow.

You’re all set! Reactiv is now connected to OneSignal. Any push notifications you trigger in Reactiv Workflows will be sent through your OneSignal account.
