Application Programming Interface (API)

While it's relatively simple to extract applicant data, you may need to import it into another system on your campus. Additionally, you may need to download applicant documents and move them to your institution's document management system. Using our APIs, you can simplify these processes and ensure your institution's data management systems and our application databases "talk" to each other by creating commands to perform specific tasks (i.e., extract this data/document, tell me when it’s ready, give me the file to download).

By using our APIs, you just "set it and forget it," meaning you'll never have to worry that a download isn’t occurring, or that it was downloaded to the wrong location. With our APIs, it just works. Furthermore, because our APIs can be called on-demand, you decide when you want to run your downloads (e.g., every day, or even every few hours).

To effectively use an API, you'll need to:

Identify what data you need (i.e., what applicants and what application data).
Define where you need to send it.
Determine how often you need to send it.

Select Your API

Liaison knows how important integrations and automation are in making our solutions work on your campus. When deciding which of our APIs to use, we encourage you first to discuss with your admissions and IT teams on how you plan to manage your admissions process and how that may align with your institution's data management systems. This can then help you select which API is best for your institution. Refer to the table below for additional suggestions.

If your campus already uses WebAdMIT™ to manage your applicant data from one or more Centralized Application Services (CASs) and you’re interested in learning more about integrating applicant data and documents into your other on-campus CRM/SIS/document management systems, check out our WebAdMIT API!
If your campus has not adopted WebAdMIT™ for admissions management but you still need to integrate CAS data and documents into your CRM/SIS/document management systems on campus using technology, take a look at our JSON-based CAS API.
If you are a current user of SlideRoom and would like to explore the API toolset available to integrate data into your on-campus systems, review the information on the SlideRoom API site.

	CAS API	WebAdMIT API	SlideRoom Classic API
Data Available	Applicant-entered CAS data and documents only	CAS data and documents + WebAdMIT data (e.g., decisions, scores, etc.)	SlideRoom data and documents
Usage Considerations	• If your institution uses one or more Liaison CASs but does not heavily leverage WebAdMIT. • If you desire notification of real-time application changes via hooks. • If your SIS/CRM supports JSON data imports & notifications.	• If your institution uses WebAdMIT significantly for application management. • If your SIS/CRM works better with batch flat file imports (CSV, fixed-width TXT).	• If your school uses SlideRoom Classic for application management.
