The external assignment identifier. If this parameter is provided and sent, it will take priority over the job_id, job_instance, and provider_id parameters to find the assignment and update it.

The date the changes being sent should be applied to the assignment. The format should be “YYYYMMDD” and it must be in UTC. For all attributes being changed, as well as time of day and/or days of the week (day_list), the changes will take effect starting on this date and ending on the existing or new end_date. Note: If this is not sent, any changes are assumed to start at the job assignment start date (either the new one being sent or the existing one if no new start date is sent).

The new end date for which the assignment should be created (the start date will be submitted as part of the attrib_list). The format should be “YYYYMMDD”, and it must be in UTC based on the request start time. For example, if the user submits a request from the Eastern Time Zone, which is 5 hours behind UTC time, and they pick a start time of 9:00 PM with an end date of 4/25/2024, the end_date sent over should be 4/26/2024, as 9:00 PM 4/25/2024 in Eastern Time is actually 2:00 AM 4/26/2024 UTC). Note: If this date and/or the start date sent in the attrib_list along with the day_list are sent with different values than the original assignment, they will be used to adjust the assignment, adding sessions and/or cancelling sessions where necessary.
