Hi. I try to write an application in .NET using OpenStreetMap API. First I want to download some GPX traces. After reading information about API version 0.6 in http://wiki.openstreetmap.org/wiki/API_v0.6 I try to use GET request
GET /api/0.6/user/gpx_files
But I receive the following exception (Error 401: Unauthorized). In fact, API documentation from wiki contains a sentence “for the authenticated user” for this GET request. How should I do to get authentication in my application? I have my own “Consumer Key”, Consumer Secret" and I know “Request Token URL”, “Access Token URL”, “Authorise URL”.
