ShipEngine Rebranded as ShipStation API

Updated February 25th, 2025

Rebranding ShipEngine as ShipStation API is the start of our next phase of providing developers, merchants, and logistics teams with the most comprehensive API tools to manage their shipping operations efficiently.

ShipEngine customers, both new and existing, don’t need to take any action to accommodate this change and you don’t need to update any of your integrations in any way. All endpoints will remain the same and continue to function as they always have. The content in the existing developer guides and API specification remain your souce of truth for building ShipEngine capabilities into your platforms.

For more details about the evolution of ShipEngine into ShipStation API, review our New ShipStation API page.
