Install Synexa Holiday Notice in the Shopify store where you want to display announcements. You need permission to install apps and customize the relevant online-store theme.

Install and open the app

  1. Open the official Synexa Holiday Notice listing or installation link provided by SynexaTech Labs. Check the app and provider names before continuing.
  2. Select the correct Shopify store and follow Shopify's installation and permission prompts. If installation is unavailable, ask your store owner or contact support.
  3. Open Synexa Holiday Notice from your Shopify admin's apps area. The app opens inside Shopify; you do not create a separate merchant account for it.
  4. Check the Dashboard and the Store timezone shown there. Open Settings if you need to change the timezone used when entering schedules.
  5. Create a notice, then use Enable announcement bar on the dashboard to open the theme editor. Enable the app in App embeds and save the theme.

What to expect

Installation connects the app to your store, but does not by itself publish an announcement. A notice must be published, enabled, eligible for its schedule, and selected under the plan's display limit. The theme app embed must also be enabled on the theme shoppers use.

The setup does not require you to paste code into a Liquid file. If you use an unpublished theme, check its embed separately: the dashboard activation check refers to the published theme.

If setup gets stuck

Reopen the app from Shopify admin rather than using a saved development or expired authorization URL. Check that you are in the intended store and have the necessary permissions. Send support your store domain, the step that failed, and the visible error. Never send a Shopify password or access token.

Next steps
