4. eTrack-Specific Settings

Service Name

It is recommended to match the courier service name used in Shopify.

This enables automatic courier selection during AWB generation based on the customer’s chosen option.

Service Status

ON – you can generate Cargus AWBs
OFF – the service will not appear in the document generation window

5. Cargus Fixed Pick-up Points – Ship & Go

To display the Cargus Ship & Go map widget on your website, follow the dedicated configuration steps in the specific documentation.

6. Generating Transport Documents

For individual AWB generation, follow the standard document generation steps.

For BULK generation, use the dedicated multiple-document workflow.

7. Managing Multiple Pick-up Locations

If you ship from multiple locations, additional configuration is required.

Step 1: Define Locations in Shopify

Shopify > Settings > Locations (e.g., Address 1, Address 2, … Address 5)

Step 2: Assign Products to Locations

Products must be assigned in Shopify exactly according to the physical stock in each location.

Step 3: Update eTrack

Close and reopen eTrack from Shopify > Apps.

Navigate to: eTrack > Profile > Your account > Fulfillment location

Enable the address selector and save.

Step 4: Configure Multiple Cargus Connectors

Create one Cargus connector per location using the same credentials.

Specific Settings:

Pick-up location – select the correct location
Service name – Cargus – [Location Name]
Save each connector

Example:

Cargus – Address 1
Cargus – Address 2
…
Cargus – Address 5

When generating the AWB, in the Courier step, select the corresponding pick-up location.

8. Important Rules

An AWB can be generated only for products assigned to a single location.
An AWB cannot be generated if products in the order are assigned to different locations.
