Announcing Instalabels (or Single Call Label Creation)

[Shan Lian]

If you already know what service level you’ll be shipping with, there’s no need to wait to get a rate every time you make a label. 

Simply send one POST request to our Transaction endpoint with your preferred carrier-account-object-id and servicelevel-token. 

This feature is currently only rolled out for USPS, FedEx, and UPS. To learn more about it, and see service level token, go here.
