Canvas Catalog is an outreach platform for non-credit/non-degree related purposes. Colleges or units may use Catalog to offer professional development, public outreach, or other certificate-based courses. Catalog extends access to those outside of the university community. Catalog offerings can be fee-based using a special payment gateway, or they can be offered at discounts based on special promotional codes, or at no additional cost to the participant. Customized certificates are available to users upon completion of activities. Catalog is a separate instance of Canvas and is the only avenue to provide external users to a Canvas-based course.
