# Alight File Format Download

This message is used exclusively in the Health Insurance arena, generally for employer provided insurance.  Alight supports both a 2500 byte and a 1500 byte file; currently only the 2500 byte file format is available in TDO.

 The API format for this  Alight file is 1.7.  Also important to note is that while you must end the URL with a “/” for most of the versions above, you must not use a terminal slash on this version.  Also, this is the only data assembly call where you use the workset name and not the datablock name to identify the source.

&#x20;The URL format is http\://\<server:port>/core/1.7/API/project/\<project\_name>/\<project\_version>/\<workset\_name>/\<workset\_version

&#x20;One of the main differences between the 834 format and the Alight format is that in the 834, each subscriber/family is a single set while in the Alight format each individual is a record; subscribers and family members are differentiated by the record type indicator.  Because of this each family member is set up in a different step in TDO. So the data assembly processes the entire workset (all steps) in one call and determines which family members to include based on their record indicator type.

&#x20;To output a file for employer ‘ACME INC’ the URL would look like this:

&#x20;[http://99.99.99.99:8080/core/1.7/API/project/alight\_project/1.0/t\_enroll1\_workset/1.0](http://99.99.99.99:8080/core/1.7/API/project/t_moccommercial_alight_project/1.0/t_enroll1_workset/1.0)

&#x20;

TDO assigns the file name based on the employer name and processing date.  The output from this file is shown below.
