Create Colissimo return labels directly from yayloh.
Before you start
A Colissimo contract, with the countries you want to offer returns from.
Your warehouse set up under Settings > Stores & warehouses. You'll choose it when you create the route.
Admin access to yayloh.
Step 1: Get your credentials
Contract number: usually numeric. If yours contains letters, call Colissimo and ask for your numeric contract number.
Password: the password to your Colissimo account.
New Colissimo contract? It can take up to 24 hours before your credentials work.
Check your credentials (optional)
You can test your credentials with the Colissimo app on Shopify, which has a 14-day free trial:
Install the Colissimo app from the Shopify App Store and choose the free trial.
Open the app, go to the configuration page and enter your credentials.
Click Check my connection settings. If your credentials are correct, they're verified.
These videos (in French) show the steps. See "Colissimo Shopify - Etape 1 & 2 - Configuration mon compte".
Step 2: Add Colissimo as a carrier
Go to Settings > Carriers & Routes and open the Carriers tab.
Click Add carrier, enter a name (for example "Colissimo"), and choose COLISSIMO as the carrier company.
Under Credentials, enter your contract number and password.
Step 3: Create a route
In the Routes tab, click Add route and choose your Colissimo carrier under Use.
Under Allow returns from, choose the countries enabled in your Colissimo contract.
Choose your Default warehouse.
No specifications are needed for Colissimo.
Step 4: Save and test
Click Apply changes, then create a test label on the Labels page.
Good to know
Labels only work for countries enabled in your Colissimo contract. To add a country, contact Colissimo first.
