I'm developing an app and I need to perform route calculation for trucks, also specifying some restrictions (weight, height and so on).
I've read on official documentation that only administrators of an organization may create/edit/delete travel modes, and only from the ArcGis online console.
Going through the REST API documentation I see that there is the possibility of getting the travel modes configured by the admin, but it doesn't mention if there is a dedicated REST service for creating, editing and deleting.
I'm asking this because I would like my customer to be able to directly insert travel modes for his/her own truck from the application by filling a form and avoid the fact of opening the ArcGis online console, is this possible?
If not, how can I speed up this process?
