Liaison CAS applicants who are In Progress have selected at least one of your programs, but have not yet submitted their application. Depending on the CAS, you may be able to receive full or partial data for these applicants. Consult Liaison's documentation for your CAS to determine if there are any visibility restrictions on In Progress applications.
There are additional optional source formats available that may be configured if desired:
All CAS by Liaison - In Progress Applications (described in this article)
🔔 Important!
Starting September 2025, in the scheduled delivery feature in WebAdMIT, scheduled jobs will be disabled if there are consecutive failures. Specifically, if WebAdMIT is unable to connect to the Slate SFTP after 10 consecutive attempts (this includes two retries for each attempt for a total of 30 connection attempts), the export job will be disabled in WebAdMIT.
Adding the source format
To add the All CAS by Liaison - In Progress Applications source format:
Select Database from the top navigation bar and select Source Format Library.
Search for "All CAS by Liaison - In Progress Applications" and select Add.
Navigate to the new source format and click Edit.
On the Import Automation tab, update the Import Path/Mask field to specify the file path and file name pattern that the source format should use to pick up the file. For example: liaison/casapi-app-started_*.csv
These file names will be configured in the CAS API subscription step.
For example, in the subscription, to configure the data files to correspond with the Import Path/Mask value
liaison/casapi-app-started_*.csv, the following settings in the CAS API subscription can be used:"sftpBaseDirectory": "/incoming/liaison/", "sftpPathTemplate": "casapi-app-started_ ___ _.csv"Note: The user account added in the previous step has access to the
/incoming/liaison/directory. If you choose to configure the CAS API subscriptions to deliver data files to different directories, then the user account must be updated to grant it access to those additional directories. Using the example path and file name pattern shown above, the pre-configured access settings can be used.
🔔 Important!
You will not be able to map any fields until you receive or manually upload a file from the CAS API. Be sure to use a file delivered by the CAS API subscription for an in-progress application to ensure that all possible data points are included. By default, blank/null values are not sent via CAS API subscriptions, so if you need to adjust remap settings for a particular source field, and you do not see it on the Fields page, you will need to upload this file again.
Configuring the remap settings
To configure the remap settings for the All CAS by Liaison - In Progress Applications source format:
Select Database from the top navigation bar and select Source Formats.
Find the All CAS by Liaison - In Progress Applications source format and select Remap to confirm destinations and to set up additional data mappings for this source format.
After selecting Remap, you will see all of the Slate destination fields currently mapped for the data points included in the file.
There is a unique for merging field that is used to properly match subsequent application data to the appropriate person record within Slate. This field is pre-mapped in the All CAS by Liaison - In Progress Applications source format:
CAS/Liaison Person ID
This field is automatically created during an overnight process that occurs after you have added the All CAS by Liaison - Applications source format. The following field is pre-mapped and should not be adjusted, nor should other fields be mapped to this destination.
Source Field | Destination Field |
|---|---|
| CAS/Liaison Person ID |
🔔 Important!
This data is considered in progress, and it does not contain a completed application. As such, application-scoped fields should not be mapped. When an application is submitted, all application data points are sent in the submitted applications API subscription configured above.
💡 Tip
Refer to Liaison's documentation for more information about the different application statuses.
What should I do if my institution accepts multiple CAS applications?
See Multiple CAS Applications.
How do I activate the import?
Refer to the section Activation below.
Activation
Use the same testing steps as with the required source format. Once you have finished testing the remap configurations, the source format can be activated in production:
