Hi Albert,

We're working on re-enabling direct linking to external backpacks at the moment, and it's currently on the roadmap for Totara 13. But in the meantime, you can still upload your badges to a backpack manually. We explain how to do this in our Help documentation here. 

Hope that helps! Do shout if you've got further questions on this - it's great to see people using our badges out in the real world!

Thanks

Rachel
