With Outvio you can use your Click & Drop credentials to print labels, send notifications, tracking, etc. Here's an easy step by step instructions on how to get your webservice credentials for Royal Mail Click & Drop.
Step 1: login to your Click & Drop account, access the dashboard and go to 'Settings' > 'Integrations'.
Step 2: From the list that appears, select 'Click & Drop API'.
Step 3: fill in the data camps.
Default trading name
Select your default trading name from the drop down list. If you only have one trading name, it will be automatically entered. This trading name will determine the return address that is displayed on your labels.
Integration name
Choose the name your integration will be displayed under within Click & Drop. It can be "Outvio Click & Drop integration".
Use shipping address for billing address
Click & Drop allows you to map both shipping and billing address data. If you select this option, you will only need to map the fields for shipping address data. This option is selected by default.
Create batches for the imported orders
Click this option if you wish for your imported orders to be automatically placed in batches. This occurs per API call, so if your API call contains 5 orders, all five will be placed in a single batch.
Click the 'Update' button when you are ready.
Step 4: your new integration is now listed in your Integrations list. Click on it and your API authorization key will be there. This is the one you need to connect to Outvio in Couriers > Click & Drop.
Step 5: you will also need your service code for each of your shipping methods. You can find them in Settings > Shipping services. Copy each of the codes and add them to Outvio under Royal Mail settings:
You will now be good to go!
