Extended data

Reference documentation for extended data.

Extended data is a set of arbitrary keys and values store with the API resources. The values for the keys can be any valid JSON values, including a JSON object (hash). This provides API clients with the capability to store arbitrary structured data for the supported resource types. Via data schema we also support querying/filtering by the extended data for some value types.

Types of extended data

Note: Extended data support in API resources is work in progress. See the API reference for each resource for information on supported extended data.

There are five types of extended data, which can be divided into two groups - data and metadata. Data is written by users via the Marketplace API, while metadata is written by operators via the Flex Console. Each type has different access semantics (i.e. who is allowed to read or write the data).

Public data

Public data is writable by whoever has write access to a given resource (e.g. listing's author can write public data about the listing, a user can write public data in their profile). Public data is readable via all API endpoints that return the resource and by marketplace operators.

Public data can be used, for instance, to store additional information about listings and users in order to help customers make buying decisions.

Protected data

Protected data is writable and readable by whoever has write access to a resource. It is also readable by marketplace operators. Protected data can be revealed to all transaction parties via the marketplace transaction process.

Protected data can be used to store information about listings or users that is only made visible to a customer at a specific point in the transaction process.

Private data

Private data is similar to protected data, but is not intended to be revealed via the transaction process. For instance, it can be used to collect and store information about users or listings for marketplace operators. It can also be used with integrations that want to store e.g. a corresponding id in an external service.

Public metadata

Public metadata is writable by marketplace operators and can be read via all API endpoints returning the corresponding resource. Public metadata is supported for listings and can also be used as filters when searching via /listings/query.

Public metadata is useful for example marking listings as promoted or for linking listings with external services.

Private metadata

Note: This feature is not yet supported by the Marketplace API.

Private metadata is only readable and writable by marketplace operators.

Data schema

Extended data is available out of the box and can be written and read via the Marketplace API without any prior configuration. Data schema may optionally be defined for some value types of extended data. When a schema is provided for a given extended data key, the API can use this information to make querying the extended data possible via some API endpoints. For instance /listings/query supports querying listings by public data.
