System and method for third party service integration into a browser client application

A system for third-party application integration into a browser client application, comprising:

• an authentication engine comprising at least a plurality of programming instructions stored in a memory of, and operating on at least one processor of, a computing device, wherein the plurality of programming instructions, when operating on the at least one processor, causes the computing device to:
• receive user login information, the user login information comprising one or more of a session ID, a device ID, and client ID;
• create a client session token, wherein the client session token is based on the user login information;
• send the client session token to a workflow manager;
• receive a wrapper token from the workflow manager, the wrapper token comprising a third-party service request and the client session token;
• parse the wrapper token to extract the client session token;
• validate a user associated with the client session token by comparing client session token data with user data stored in a database;
• send the third-party service request to the appropriate third-party service;
• receive, from the third-party service, one or more third-party data objects;
• and
• send the one or more third-party data objects to the workflow engine;
• and
• the workflow engine comprising at least a second plurality of programming instructions stored in a memory of, and operating on at least one processor of, a second computing device, wherein the second plurality of programming instructions, when operating on the at least one processor, causes the second computing device to:
• receive the client session token from the authentication engine;
• receive the third-party service request, the third-party service request comprising service request information;
• create the wrapper token by combining the third-party service request information with the client session token;
• send the wrapper token to the authentication engine;
• receive the one or more third-party data objects;
• and
• display the one or more third-party data objects in a browser-based application user interface.
