Getting Information About My Organization
The examples in this section use REST API resources to retrieve organization-level
information, such as a list of all objects available in your organization.
-
List Available REST API Versions
Use the Versions resource to list summary information about each REST API version currently available, including the version, label, and a link to each version's root. You don’t need authentication to retrieve the list of versions. -
List Org Limits
Use the *** resource to list your org limits. -
List Available REST Resources
Use the *** resource to list the resources available for the specified API version. This provides the name and URI of each additional resource. -
Get a List of Objects
Use the Describe Global resource to list the objects available in your org and available to the logged-in user. This resource also returns the org encoding, as well as maximum batch size permitted in queries. -
Get a List of Objects If Metadata Has Changed
Use the Describe Global resource and the If-Modified-Since HTTP header to determine if an object’s metadata has changed.
