Our Culture - Innovation


Much like our company culture, we seek to embrace change by the continuous reinvention of ourselves and how we interact with our customers.  The Developer Portal is an extension of this philosophy by making it easier for clients to get their data through a self-service model with less reliance on SEI and transforming our physical services into digital offerings.  


                          "A big part of it is pushing collaboration....

                            ......creating new innovations is a process that takes more than one person." 


                                                       -- Al West, CEO.


SEI (NASDAQ: SEIC) is a leading global provider of asset management, investment processing, and investment operations solutions for institutional and personal wealth management.

Our Standards - Developers First


The Developer Portal is a presentation of SEI's API products available.  It provides rich documentation centered around REST principals.  Representation State Transfer (REST) is an architectural style that specifies constraints, such as uniform interface, that if applied to a web service induce desirable properties such as performance, scalability, and modifiability that enables services to work best on the Web (source: docs.oracle.com).  


We use features ingrained in HTTP such as verbs and authentication that permit use by mobile and web based applications.  We have test and production API endpoints that can be used for exploration, all of which return JSON responses.  


Our infrastructure is geared towards reliability and can accommodate millions of API calls per year with the ability to scale up as we grow.


Once you've created an account and registered your application, you'll be able to use your API key and secret to begin building on behalf of your business partners and customers.
