How can I create links using a dropdown containing codes created on another workspace?

You may use a workspace to make a campaign / asset / Salesforce codes/ID's to ensure a clean naming taxonomy in your other marketing systems. You may wish to select these codes in your workspace where you create links to save time and reduce errors.

First you need to make a workspace for creating codes (not links / QR codes)

Then need to add a workspace code parameter into your workspace you create links and QR codes.

How to create a workspace for creating codes or ID's

1. As an admin, in the top-right workspace dropdown, scroll to the bottom and click "+ Add workspace"
2. Name the workspace something like "Create campaign code/asset code/Salesforce ID"
3. Uncheck 'Copy link taxonomy, parameters, dropdowns and rules' checkbox
4. In bottom-right click the "Create new workspace" pink button
5. Setup your taxonomy in Track > Edit parameter rules
6. In Advanced rules > Destinations, uncheck "Require landing page" AND "Show landing page field"
    
   This will turn your workspace into a place to create codes, rather than links.
    

How to create a parameter from codes created in other workspaces

1. As an admin, go to Track > Edit parameter rules
2. In the top-left, click on the "+ Add parameter" button
3. In the model, name your parameter
4. Under input type, select "Workspace code" parameter
5. Select the workspace you wish to take the the code from

6. In the bottom-right click "+ Add parameter" pink button

   The Track > Create links dropdown will now show created codes from your other workspace.
