# JSON Pointer syntax

JSON Pointer defines a syntax for identifying a specific value within a JSON payload. Using the following sample payload and JSON Pointer examples, identify the attributes you want to use to populate your attribute contract.

You can find a complete technical description of JSON Pointer syntax in [IETF RFC 6901 - JavaScript Object Notation (JSON) Pointer](https://tools.ietf.org/html/rfc6901).
