422 Unprocessable Entity when attempting to answer a quiz question

[quantumblink]

I am attempting to answer a Quiz Submission Question with the API.  I'm first trying to answer a multiple choice question. When a user presses on a button to select an answer, the answer is intended to be submitted. I structured my request to be:

{"quiz_questions":[{"answer":1108,"id":"6"}],"attempt":5,"access_code":null,"validation_token":"0271914e7b879b57228597b866c07ef03fee1a600578a06d65eb4151a8ee8437"}

However, I get a 422.

I have attempted to remove the id field in answer with no luck.

I observed that the web API uses a `backup` endpoint that isn't documented. Is that related at all?

Instead of using "quiz_questions":[{"answer":1108,"id":"6"}]

try "quiz_questions[][id]":6,"quiz_questions[][answer]":1108

I've been successful with this format. Hope it helps you...

If you want to use JSON, then for some of those entries that expect arrays, you may need to use a hash to fake an array by specifying the index of the array as the key of the object. I'm typing this from memory without testing, so I might have something off slightly. If you needed more than one element in the array, you would create a "1" object and a "2" object.

{
  "quiz_questions": { "0": {"answer": 1108, "id": 6} },
  ...
}
