Hello again!
Meanwhile I had someone else resolve the other two questions I posted here.
I don’t know how it was done but you can check the code on my website if it helps.
What is still not working is the categories.
I read in this forum that you can see product categories or other information you need in the URL on your Spreadshirt website. But if I check any URL the only thing I see is the shop ID. ( i. e. https://partner.spreadshirt.at/shop-area/100609573/shop )
I have never been able to do more than listing ALL products that are in my Spreadshop.
It would be great to hear back from you!
Best,
Anna
