4. Reconnecting or Reinstalling
If you've removed Postflows from your Shopify store and want to reconnect it, your previous data is preserved and the store can be reactivated without losing any history.
What happens when you uninstall
When Postflows is uninstalled from Shopify:
Your store is marked inactive in Postflows
Shipping event notifications stop immediately
Your billing subscription is paused (no further charges)
All your data is kept - orders, settings, integrations, and history are not deleted
See Uninstalling Postflows for the full details.
How to reconnect
Reconnecting follows the same steps as the original installation:
Reinstall Postflows from the Shopify App Store
Go through the Shopify authorization flow
Postflows detects your existing store record and reactivates it
When reactivated:
Your previous orders, event settings, rules, and integrations are all restored
Shopify webhooks are re-registered automatically
Your subscription is reactivated
Reconnecting a disconnected integration
If your Klaviyo or Omnisend connection is showing as disconnected (without uninstalling the app):
Go to Dashboard > Integrations
Click Connect next to the affected platform
Complete the authorization flow
This refreshes the connection without affecting your store data or settings.
Troubleshooting
I reinstalled but my previous settings are gone If your store isn't being recognized as a returning install, contact support with your Shopify store domain.
My integration stopped working after reinstalling Reconnect your Klaviyo or Omnisend integration from Dashboard > Integrations after reinstalling.
