I would like to export a static image of a map and all its layers, using the ArcGIS REST API. I have followed the DevLabs example here, using Postman: Export a static image of a map | ArcGIS for Developers However, the response returned after following steps 1-6 exactly as specified is: { "error": { "code": 400, "extendedCode": -2147467259, "message": "Unable to complete operation.", "details": [ "Expected property name; state : inPropertyValue; buffer : :null,\"Format\":null,\"Layout_Template\":null" ] } } Can anyone advise what I am doing wrong, and why the example given does not work? ----- UPDATE: Figured out why the example doesnt work - In Postman the default Content-Type is form-data, it has to be x-www-form-urlencoded to work correctly
