API Configurations

Service Account Configurations

To enable automated delivery of CAS application data through the API, Slate requires each instance to have a “CAS/Liaison Service Account” (functionally a “user”) which is assigned a role that allows SFTP access. This “user” is what holds the permissions, allowed networks, and other security settings to allow the data to be transferred from the CAS environment into the Slate environment via SFTP.

The CAS/Liaison Service account is pre-configured in Slate and available from the Slate Template Library (STL). Instructions for adding it are in the Slate KB.

Password

Copy and save the password prior to saving changes, because once saved, the password will not be visible. You will need the password to configure the CAS API subscription with Liaison. 

Allowed Networks

Below are the IP addresses that are included in the “allowed networks” of existing CAS/Liaison Service accounts for future reference. It is unclear which exactly are used by the Liaison systems, the following list is provided for reference/troubleshooting.

Using Postman and Endpoints

...

  1. Select the environment for the CAS application you are trying to access, and send a call for an authorization token (POST Call Auth Token).

  2. Next send a call to the GET applications list. The response will contain details for every application in the CAS and cycle (application form ID) and the school/college/university (organization) established in your environment. Use the search tool in Postman to search for the name or CAS Applicant ID of the applicant you are trying to find; make note of the application ID.

  3. Open the GET individual application endpoint. Paste the application ID into the value under the “Params > Path Variables” section. Next, in the Headers menu make sure that Accept is set to text/csv (default is application/json, changing this ensures a text file is returned). Save the endpoint and then send it.

  4. Save the response locally.

  5. Open Excel, use “Open” to find the file that you saved in the previous step. Make sure to change the type of file you are looking for to “All Files.”

  6. Excel may give a warning, but click yes to open anyway. Excel will then run through the Text Import Wizard. Select Delimited for Step 1, then “comma” in Step 2, and then finish. The workbook will open; save as a CSV file.
