NPF/NP Fulfilment

NPF/NP Fulfilment Integration — Shopify Edited Order Sync (Account Editor)

This guide helps merchants using NPF/NP Fulfilment (OMS) understand how to configure the integration so that Account Editor order edits are always reflected correctly. NPF does not read live edits — orders must be fully finalized before NPF downloads them.

Important: NPF/NP Fulfilment uses the **Account Editor Delayed Master Flow to delay order downloads. Payment is held in Authorized state while customers edit, then the Flow captures payment automatically after the grace period — triggering NPF to download the finalized order.**

How the Integration Works

NPF/NP Fulfilment downloads orders from Shopify only when payment status is "Paid". The Account Editor Delayed Master Flow creates a grace period between order creation and payment capture — giving you time to edit the order in Account Editor before NPF ever sees it.

Step 1 — Order Created

Customer places an order → Payment is Authorized (not yet captured).

Step 2 — Grace Period Active

The editing window opens. Customer or merchant can edit the order in Account Editor — add items, remove items, change quantities, update address.

Step 3 — NPF Skips the Order

Because payment status is still `Authorized`, NPF does not download the order. The order is invisible to NPF during the entire editing window.

Step 4 — Grace Period Ends

Shopify Flow automatically captures payment → Status updates to Paid.

Step 5 — NPF Downloads

NPF sees the order for the first time with all edits already included — correct items, quantities, and totals.

Step-by-Step Setup

📋 Step 1 — Change Payment Capture Setting in Shopify

Set Shopify to hold payment in Authorized state so NPF cannot import the order until editing is complete and payment is captured.

Log in to Shopify Admin
Go to Settings → Payments
Scroll down to Payment capture method
Select "Manually"
Click Save

⚠️ 7-day limit: Shopify Payments authorizations expire after 7 days. Always ensure your grace period is well within this window.

⚡ Step 2 — Import the Account Editor Delayed Master Flow

The Account Editor Delayed Master Flow is a pre-built Shopify Flow automation that holds payment capture for a configurable grace period, then captures automatically — triggering NPF to download the finalized order.

Download the Account Editor Delayed Master Flow file (provided with this guide)
In Shopify Admin, go to Apps → Shopify Flow
Click Import and select the downloaded .flow file
Configure the grace period timing to match your editing deadline (e.g., 30 minutes)
Click Activate to enable the Flow
Click Save

📝 How the Flow works: When a new order is created, the Flow waits for the configured grace period. After the wait, it automatically captures payment — changing the status from Authorized to Paid. NPF then downloads the order with all edits included.

🚫 Step 3 — Disable Shipping Methods App Block in Account Editor

NPF/NP Fulfilment does not support shipping method changes during the editing window. To prevent customer confusion, you must disable the Shipping Methods App Block in Account Editor settings.

Open your Account Editor app settings in Shopify Admin
Navigate to the App Blocks configuration
Find the Shipping Methods App Block
Toggle it OFF
Click Save

🛑 Do not skip this step. If the Shipping Methods App Block is left enabled, customers may attempt to change their shipping method during the editing window. NPF will not reflect these changes, leading to incorrect shipping and customer complaints.

✏️ Step 4 — Your Account Editor Workflow

Once setup is complete, this is the automated flow for every order:

New order arrives → Payment = Authorized (NPF does not see it ✅)
Grace period active → Customer can edit in Account Editor — add/remove items, change quantities, update address
Grace period expires → Shopify Flow automatically captures payment
Payment becomes Paid → NPF downloads the finalized order ✅
Order is processed with all edits included — no manual intervention needed

What happens after this setup:

✅ Correct order total — removed items not counted
✅ Added items appear correctly in NPF
✅ Quantity changes reflected accurately
✅ Address changes included in the download
✅ No manual payment capture needed — fully automated

✅ Setup complete! NPF will always receive the final, correctly edited order. The entire flow is automated — no manual capture or NPF configuration required.

Settings Summary

Where	Setting	Value
Shopify → Settings → Payments	Payment capture method	`Automatically after fulfillment`
Shopify → Apps → Shopify Flow	Account Editor Delayed Master Flow	Active — grace period configured
Account Editor → App Blocks	Shipping Methods App Block	Disabled
Account Editor → Settings	Editing Deadline	Configured (e.g., 30 min)

Testing Checklist

Before going live, run through this checklist to confirm everything works correctly:

✅ Place a test order — verify it does not appear in NPF immediately
✅ Make edits during the editing window — add/remove items, change address
✅ Wait for the grace period to expire
✅ Confirm payment is captured automatically by the Flow
✅ Confirm order appears in NPF with all edits included
✅ Verify shipping method changes are blocked (App Block disabled)

Troubleshooting

Issue	Likely Cause	Fix
Orders appearing in NPF too early	Payment capture not configured correctly, or Flow not activated	Verify payment capture setting and confirm the Account Editor Delayed Master Flow is Active
Orders not appearing after grace period	Flow is not capturing payment correctly	Open Shopify Flow → check the run history for errors → re-import if needed
Edits not reflecting in NPF	Edits were made after the grace period ended	Ensure all edits are completed before the grace period expires — NPF does not read live edits
Authorization expired (no payment captured)	Grace period exceeds 7-day limit	Reduce grace period to well under 7 days (recommended: 30 min – 2 hours)

Best Practices

Always disable the Shipping Methods App Block — NPF cannot process shipping changes
Keep the grace period short — 30 minutes to 2 hours is ideal for most stores
Sync the editing deadline in Account Editor with the Flow timing so customers see an accurate countdown
Monitor Shopify Flow run history after launch to confirm payment captures are firing correctly
Test the full flow end-to-end before going live with real orders
