Connect Swap to your Linnworks account as a shipping carrier integration, so orders can route through Swap for label generation and fulfilment.


Before you start

Make sure you have:

  • Admin access to your Linnworks.net account
  • A Swap API account and credentials — if you're not sure, contact your Swap account manager

Step 1: Find and connect Voila

  1. In Linnworks, go to Shipping > Integrations.
  2. Click + Add Integration.
  3. Search for Voila (developer: The Despatch Company) and click Integrate.

Step 2: Authorise the connection

  1. You'll be asked to sign in with your Linnworks.net account and agree to the terms. The OAuth app is called ‘Shipping by Despatch Cloud’, but will connect you to Voila.

Managing your Swap services

  1. Back on the Integrations screen, click Services next to your new integration.
  2. Use the dropdown to add the shipping services you need, then click Add. Only custom presets populate here — system presets won't display, and it can take up to two minutes for new presets to appear.
