Create Simple Web Map via API REST

[PilarArregui]

Following the instructions on this page Working with users, groups, and items—ArcGIS REST API: Users, groups, and content | ArcGIS for Devel... I was able build a POST request in POSTMAN  to add a new item to the user.

After getting the token, when I try the POST request to add the web map I get this error

{"error":{"code":403,"messageCode":"GWM_0003","message":"You do not have permissions to access this resource or perform this operation.","details":[]}}

The JSON I used is this:

{
"operationalLayers": [],
"baseMap": {
"baseMapLayers": [
{
"id": "defaultBasemap",
"layerType": "ArcGISTiledMapServiceLayer",
"url": "https://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer",
"visibility": true,
"opacity": 1,
"title": "Topographic"
}
],
"title": "Topographic"
},
"spatialReference": {
"wkid": 102100,
"latestWkid": 3857
},
"authoringApp": "WebMapViewer",
"authoringAppVersion": "5.4",
"version": "2.11"
}

Pilar,

The username you are using in AGOL, does it have the right role assigned that allows content to be created. Can you create & save a webmap using the standard menuitems in AGOL using this username?

Hi Ryan, 
The username I'm using in AGOL is an ArcGIS developer account. As far as I know this kind of user has an admin role and all permissions available. And I can create a WebMap in the ArcGIS webpage without problems.

Turns out I was using the wrong access token. I was using the app access token instead of the user access token. 

With the user access token it works now.

Hi Pilar

Can you describe this last step in more detail? I believe I am facing a similar issue?

I had this problem too. Turns out you need an OAuth token and not the token from generateToken. The code I used is here: https://gist.github.com/YikChingTsui/ff6d7b6126db73a77e5845576250177d
