Question

I'm trying to get Moodle's quizzes as JSON. I've already tried

To get all quizzes from a specific course. And

To get a specific quiz.

Answer 1

I think that you are referring to this document. If you read closely, you'll notice that it's a proposal about how the quiz web service should be written.

In fact, when I tried your query, to get all quizzes from a course, I got:

{"exception":"dml_missing_record_exception","errorcode":"invalidrecord",
 "message":"Can not find data record in database table external_functions.",
 "debuginfo":"SELECT * FROM {external_functions}
              WHERE name = ?\n[array (\n  0 => 'get_quiz',\n)]"}

Moodle didn't found the external function get_quiz. That means... unfortunately, as of now, Moodle does not have a web service for quizzes.

If you feel adventurous, and what you need is just getting the quizzes, you could implement a web service to do that. The relevant moodle table about quizzes is mdl_quiz (for a full schema, look at this article), and here's the tutorial that shows how to implement it: Adding a web service to a plugin - Moodle Docs.

mod_quiz_get_quizzes_by_courses is the function that does the job. How to call it
