Creating API for online language school with reservation system LMS question

I am a real newbie here, but we are an online school.
We have an LMS that includes the student IDs (Username) and also teacher IDs.

We are currently using a software called Electa and an API that does that job for us.
When the students click on the link to go to the classroom in our bespoke LMS system, it takes them to a classroom with a login page.

When they log in, their username is taken from the system and used to enter the online classroom.
Basically we want to do the same thing with Zoom.

Is it possible for someone to point us to the correct API that we should use in this case?
Looking forward to a helpful reply
