We've recently added the Category ID dimension to our Marktplaats connector in Funnel!
Here's a list of fields that are currently supported by our Marktplaats connector:
[Dimension] Category ID - New
[Metric] Total Spent
[Metric] URL Clicks
Please note that no action is required to populate data for Category ID going forward.
We hope that you find this update useful! If you have any questions or if you would like to see historic data for this dimension, please contact firstname.lastname@example.org and we'll be happy to help.
