2. Connecting your store

Connecting your Shopify store to Postflows is done through Shopify's standard app authorization flow. It takes about a minute and only needs to be done once per store.

1. How to Connect Your Shopify Store

When you connect your Shopify store, Postflows requests a set of permissions to access your store data. This article explains what each permission is for.

2. Permissions Postflows Requires and Why

3. Events

Postflows automates post-purchase notifications by listening for shipping events - milestones that occur as your customer's order moves from checkout to delivery. This article explains how events work and what happens when one fires.

1. Shipping Events Overview

Postflows supports 8 shipping events. This article describes each event, when it fires, and what carrier situations it covers.

2. Available Events and What Triggers Each One

All 8 shipping events are enabled by default when you set up Postflows. You can turn individual events on or off at any time from the dashboard.

3. Enabling and Disabling Events

Postflows does not send emails directly. Instead, it detects shipping events and forwards them to your email platform - Klaviyo or Omnisend - which then triggers and sends the notification to your customer.

This article explains exactly what Postflows sends, how it appears in your email platform, and what data you have available for personalization.

4. How Postflows Works with Klaviyo and Omnisend

4. Rules and Filters

Order filters decide which orders Postflows processes. If an order is blocked by an order filter, none of its shipping events will be forwarded to your email platform - regardless of which events are enabled.

By default, with no filters configured, Postflows processes all orders.

1. Order Filters

Event filters run after order filters and decide whether a specific shipping event is send to your email platform. While order filters control which orders enter the pipeline, event filters control which individual updates are sent.
