The Representational State Transfer (REST) API is an inherently lightweight and intuitive Web interface for viewing ArcWeb Services maps. The REST API permits you make requests to ArcWeb Services via a URL. For a look at how this API compares to the others, see the ArcWeb API chart.
The ArcWeb Services implementation of the REST API easily allows you to perform the following functions:
The REST documentation includes information on getting a map, map parameters, raster tile parameters, projections, samples, and error messages.
To use REST with ArcWeb Services, you need an active subscription to ArcWeb Services. Most ArcWeb requests consume credits from a user account. See Understanding credits and costs for more information.
ArcWeb Services uses an authentication system to validate access to its services and data. See REST authentication for details on authentication using REST.
