[ARCHIVED] Bad request when posting user against rest api

[StefanNorinder]

Dear Community, 

I'm trying to create a user with Canvas rest api. Here's the json I'm posting: 

{

   "user":{

      "Name":"Foo bar"

   },

   "pseudonym":{

      "Unique_id":"foobar@mailinator.com"

   }

}

And here's the response from Canvas: 

{

    "errors": {

        "user": {

            "pseudonyms": [

                {

                    "attribute": "pseudonyms",

                    "type": "invalid",

                    "message": "invalid"

                }

            ]

        },

        "pseudonym": {

            "unique_id": [

                {

                    "attribute": "unique_id",

                    "type": "invalid",

                    "message": "invalid"

                },

                {

                    "attribute": "unique_id",

                    "type": "too_short",

                    "message": "too_short"

                }

            ]

        },

        "observee": {},

        "pairing_code": {},

        "recaptcha": null

    }

}

I've tried a lot of different syntaxes but with the same result. Please help.

You can always do a test creation on your instance using: https://yourserver.instructure.com/doc/api/live#!/users.json/create_user_post_12 and you'll see the json used.

It's quite possible that if you do a create user in the UI, your browser will also capture the json used in your Developer Tools.

Thanks @dtod for your reply! 

I managed to figure out what was wrong. `Unique_id` needs to be in lowercase. Since I pass `Unique_Id` I guess Canvas gott `null` and went "well, this ID is way to short!" 

So all is well, for now.
