Cart API, v3 url changes

I am currently using the “cart API” to get a list of the carts (and their cart ID’s) registered in a particular account, so that I can properly categorize the incoming orders when we import them into our system.

I just got a note from support saying we need to make sure we’re using as our API URL by 8/17. But this cart API’s URL is

Can you please assist me so that I can get this ready for the 8/17 changeover? I could not find a “cart” API in the v3 documentation.

… but in the new documentation I cannot find the above … will this continue to be supported? Is it just missing from the new documentation?



Hey, @RPZwilling

The /v3/label endpoint is still available. It’s listed in the documentation here.

Ok thanks … sorry I could not find this in the documentation.

No worries! Any feedback is appreciated. We’ll check on moving that around to make it more visible.
