Autodesk BIM360: Folder Creation returns 400 Bad request - autodesk-data-management

Question

I called the POST-Folder Method via Postman with a JSON body according to this example. But I only receive the message "400 Bad Request" without any explanations. This is what my request looks like:
The service adress:
https://developer.api.autodesk.com/data/v1/projects/b.5823d0b2-0000-0000-00/commands
The HTTP-header
Authorization: Bearer 2_legged_token
Content-Type: application/vnd.api+json
The JSON-Body
{
"jsonapi": {
"version": "1.0"
},
"data": {
"type": "commands",
"attributes": {
"extension": {
"type": "commands:autodesk.core:CreateFolder",
"version": "1.0.0",
"data": {
"requiredAction": "create"
}
}
},
"relationships": {
"resources": {
"data": [
{
"type": "folders",
"id": "1"
}
]
}
}
},
"included": [
{
"type": "folders",
"id": "1",
"attributes": {
"name": "test",
"extension": {
"type": "folders:autodesk.bim360:Folder",
"version": "1.0.0"
}
},
"relationships": {
"parent": {
"data": {
"type": "folders",
"id": "urn:adsk.wipprod:fs.folder:co.Ai*****"
}
}
}
}
]
}
The response
{
"jsonapi": {
"version": "1.0"
},
"errors": [
{
"id": "f1266e76-a37e-400b-bff6-de84b11cdb00",
"status": "400",
"detail": "BadRequest"
}
]
}
What I have found out so far:
The project id is right. When I take a wrong project id I receive a different error.
The Json is also valid.
When I take a (surely) wrong parent-folder-urn I'll receive the same error message. So maybe this is a wrong urn format or something?

Answer 1

As of now, you can create a BIM 360 Docs Folder with commands endpoints, as you pointed out. For that you can use:
3-legged token
2-legged token with x-user-id header, this should contain the Autodesk User ID obtained, for instance, from GET users#me endpoint
"pure" 2-legged token will return bad request (as of August/2017)
Sorry about the documentation, the endpoint to create BIM 360 Docs folder via Commands was released a couple weeks back and we're just finishing to write the documentation.
