Bronto’s SOAP API has an associated Java SDK and PHP Client Library. The Bronto Java SDK is built using sbt and is broken up into two projects. The first is the wsimported Java models, that live in com.bronto.api.model. The second is the SDK wrapper that provides a convenient API for various apps. The PHP Client Library is an ActiveRecord Style Abstraction of the Bronto SOAP API.
Both are free to use, but comes with no official support. If necessary, you can contact an Account Manager to discuss a Professional Services engagement for more assistance.
Our REST API currently does not offer an SDK.
