The SEI Developer Portal is used for communication with our developer community. Browse our API product and integration offerings, understand the functionality of SEI APIs through interactive documentation, register an application, and view analytics. In addition, receive support and stay in touch with the community through blogs and forums.

Many different roles can benefit from the SEI Developer Portal, including App Developers, Business Analysts, Product Managers, and more.

Developers can register an App, consume SEI APIs, and benefit from tools to build apps quickly. Business analysts can view API documentation to understand how the APIs fit into their application requirements. Product managers can build analytical reports by viewing application data about the usage of APIs.

Users registered with the SEI Developer Portal can access approved offerings. Please contact APISolutions@seic.com to be granted access.

An API product is a logical grouping of API endpoints bundled and published so that developers can consume them. Products can be viewed in the API Catalog.

Product documentation enables users to understand the functionality and content of SEI APIs. The interactive document includes descriptions, definitions, sample requests, and sample responses for each endpoint.
