To use any of the ČVUT Grades modules, you should have a CTU account (created automatically for all students and employees of CTU in Prague) and access to the FIT Klasifikace system (created automatically for all CTU FIT students).
To connect the ČVUT Grades app with FIT Klasifikace, follow the general instructions for Connecting to services. After you click the Continue button, Integromat will redirect you to the SSO gateway website where you will be prompted to grant Integromat access to your account.
Here, allow access by clicking the Allow button. Afterwards, you will be redirected back to the Integromat administration page. Now, you can continue creating your scenario.
