# Resource ID Each resource has a corresponding ID, for example, `NzAwNTUxOTA5NzczMTQ4MTYw`. After successfully creating the resource, the user will receive the returned ID and must provide this ID when accessing the resource. Clients should treat this ID as an opaque string and should never attempt to assemble it. This document imposes no constraints on the format, and clients should never impose any. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
