# Introduction

The Travelers Developer Platform exposes a suite of B2B REST APIs that integration partners
use to transact across insurance lines of business. Every API shares common conventions for
authentication, environments, errors, and pagination, and all of them are available through a
single combined [SDK](/documentation/sdks).
