Before you start
- Have your ITD Global Account Name confirmed by your account manager — it must start with 'ITD ' followed by a space and your business name
- Have your ITD Global Customer Reference number to hand — it starts with 16 and is in your welcome email or contract
- Have admin access to Linnworks
Step-by-step guide

Add your shipping services
- On the Integrations page, click Services next to your ITD Global line.

- Click a service name, then click Add. Repeat for each service you need.

Update the Vendor Name for each service
- Go to Shipping > Postal Services in the sidebar.
- Click the Vendor column header to sort.
- Find rows showing CONNEXX Integration in the Vendor column.

Important
Repeat Step 5 each time you add a new service. Without the correct vendor name, tracking data will not route to the carrier and tracking updates may fail.
Troubleshooting
| Issue | What to do |
|---|---|
| I cannot find ITD Global or Connexx in the search | Try both search terms: 'ITD Global' and 'Connexx'. If neither works, contact ITD Global support to confirm the integration is available on your account. |
| The Account Name is being rejected | The name must start with exactly 'ITD ' — capital letters followed by a space. Copy it from your welcome email to avoid typos. |
| My Customer Reference number is not being accepted | Customer Reference numbers begin with 16. Check your welcome email or ask your account manager to confirm the correct number. |
| Services are not appearing in the dropdown | Wait 2–3 minutes after setup and refresh. If services still do not appear, contact ITD Global support with your Account Name. |
| Tracking is not writing back to Linnworks | Confirm the Vendor Name for each service has been updated correctly in Step 5. If vendor names are correct and tracking is still missing, contact support with the Linnworks order reference. |
