I just upgraded to Moodle 3.4 from 3.1.
In 3.1, there was a secret key that had to be entered so that when users from another program clicked on the external link, they would be LTI enrolled in the right course in Moodle.
But, I cannot find anywhere to enter that secret key in 3.4. I read all the Moodle docs, and they are very vague, and even inaccurate.
Can someone walk me through it please and tell me exactly what screens to go to and how to get there? I have the keys, but students are arriving this morning and won't be able to access Moodle through LTI, so it is rather urgent.
