Installation and onboarding

Install the app

Section titled “Install the app”

  1. Open the Shopify App Store

    Search for Transdirect in the Shopify App Store, or use the install link provided by Transdirect.

  2. Add the app

    Click Add app and approve the requested permissions. These let Transdirect provide rates, read your products and orders, and optionally write fulfilments.

  3. Open the app in Shopify admin

    Go to Apps → Transdirect. First-time installs land on a short Welcome screen, then the Connect account step. You link the shop by signing in to a Transdirect account or creating one — there is no API key to paste.

Connect your Transdirect account

Section titled “Connect your Transdirect account”

On Connect account you choose one of:

PathWhat happens
I already have an accountSign in with your Transdirect email and password. The shop is linked to that account.
I’m newCreate a Transdirect account for this shop. You choose an approximate weekly freight-spend bracket first, which sets your initial pricing tier, then a free Transdirect account is created from your Shopify store details and linked.

Once the account is linked, the onboarding wizard starts. You can change every decision later from Settings.

Setup wizard (first run)

Section titled “Setup wizard (first run)”

The wizard takes a few minutes. The steps run in order:

StepWhat you set
1. WelcomeA short orientation, shown on first run only.
2. Connect accountSign in, or create an account and choose your freight-spend bracket.
3. Packing modeHow orders leave the warehouse: ship in the product’s own packaging, or repack into your cartons. Includes a sample packing preview.
4. DimensionsFallback length, width, and height for variants with no dimensions. Per-product values are set on the Products page.
5. BoxesThe box library used for order boxing. Pre-filled with five common Australian sizes, which you can edit or replace.
6. CouriersYour domestic and international line-up: which services to offer, and how they appear at checkout.
7. PricingHow rates appear at checkout, such as live rates, a markup, or flat pricing. Live rates need a Shopify plan that allows third-party calculated rates.
8. Order syncWhich paid orders flow into Transdirect — all of them, or only Transdirect-rated ones — and whether to start fresh or backfill earlier orders.
9. Plan check and reviewA summary of your choices. The app registers the Shopify carrier service for live rates, then sends you to the Dashboard.

If carrier registration fails — because the plan does not support third-party rates, or Shopify returns an error — you can still finish onboarding. Checkout will not show live Transdirect rates until it is resolved. The Dashboard shows carrier-service status and how to retry.

Product dimensions

Section titled “Product dimensions”

Accurate weights and dimensions drive volumetric pricing.

In Shopify

Section titled “In Shopify”
  • Set the weight on each product and variant under Products.
  • Shopify records weight in kilograms. The Transdirect app records dimensions in centimetres.

In the Transdirect app

Section titled “In the Transdirect app”

After onboarding:

  1. Open Apps → Transdirect → Products (from the Dashboard shortcut).
  2. Edit dimensions per product or variant in the spreadsheet view, or use Multi-box import for large catalogues.
  3. Variants without dimensions fall back to Settings → Default item size.

Multi-box import is a CSV round trip: export a file pre-filled with your Shopify products and any existing box configuration, fill in the box dimensions in Excel or Google Sheets, then upload it again.

After onboarding

Section titled “After onboarding”

You land on the Dashboard, which includes:

  • Links to Settings (shipping preferences hub) and Products
  • Recent shipping and rate activity, including any errors
  • Carrier-service status (whether live checkout rates are registered)

From Settings you can revisit quote options, defaults, warranty, order sync, multipickup, order boxing, and show-on-cart. The packing, courier, and pricing cards reopen the matching setup step.

Plan requirements

Section titled “Plan requirements”

Live carrier rates require Shopify third-party calculated shipping, which is included with Advanced and Plus plans and available as an add-on on some others. The plan check during onboarding is the authoritative test. If it fails, upgrade your Shopify plan or purchase the add-on, then retry the carrier install from the Dashboard.

Upgrading the app

Section titled “Upgrading the app”

Shopify delivers app updates through the App Store. Re-open Apps → Transdirect after an update. Your linked Transdirect account, settings, and completed onboarding are all preserved.
