API: 422 Error Creating User

[kurt4]

I am trying to POST a user via API, but I am receiving a 422 Error (Semantic Error, meaning the request is syntactically correct) from the API. This only happens with the POST request for the User. I am able to GET Users via API, but unable to POST a new user. Here is the endpoint I am using: Users - Canvas LMS REST API Documentation.

I have verified that I have the correct scopes and that my auth token is not expired. 

I am using Postman to test this request, and it generated this cURL:

curl --location --request POST 'https://<org-url>/api/v1/accounts/1/user' \
--header 'Authorization: Bearer: <access-token>' \
--header 'Content-Type: application/json' \
--header 'Content-Type: text/plain' \
--data-raw '{
 "user": {
 "name": "System Test",
 "short_name": "System",
 "sortable_name": "Test, System",
 "terms_of_use": true
 },
 "pseudonym": {
 "unique_id": "kurtvolmar+systemtest@gmail.com"
 },
 "communication_channel": {
 "type": "email",
 "address": "kurtvolmar+systemtest@gmail.com"
 }
}'

I would greatly appreciate some direction for solving this. Thanks!

Hey  @kurt4 ,

I didn't test it, but I think your Post link has to end in users (plural) instead of user. I believe that would cause a 422 unprocessable error. 

curl --location --request POST 'https://<org-url>/api/v1/accounts/1/users'‍‍
