The Metafield resource allows you to add additional information to store's resources. Metafields can be used in several ways, such as to add a summary to a blog post. You can also use metafields to share information with other Haravan apps.

Metafields have four required properties: a key, a namespace, a value and a value_type. The key is the identifier for a metafield. The namespace functions a container for a set of metafields which help to distinguish between metadata that you created and metadata created by others with a similair namespace. The value is the content of the metafield. The value_type describe the state of the value, whether it is a 'string', an 'integer' or an 'json'. There also exists an optional description property that provides additional information about the metafield. 


What can you do with Metafield?


The Haravan API lets you do the following with the Metafield resource. More detailed versions of these general actions may be available:



Metafield Properties

created_at

{ "created_at": "2021-11-30T08:40:33.594Z" } read-only

The date and time when the metafield was created. The API returns this value in ISO 8601 format.

updated_at

{ "updated_at": "2021-12-13T06:32:35.731Z" } read-only

The date and time when the metafield was published. The API returns this value in ISO 8601 format.

description

{ "description" : "abc" } optional

Additional information about the metafield.

id

{ "id" : 915396206 } read-only

The unique ID of the metafield.

key

{ "key" : "warehouse" }

The name of the metafield. Minimum length: 3 characters. Maximum length: 30 characters.

namespace

{ "namespace" : "inventory" }

Container for a set of metadata. Namespaces help distinguish between metadata you created against metadata created by another individual with a similar namespace. Minimum length: 2 characters. Maximum length: 20 characters.

owner_id

{ "owner_id" : 690933842 }

The unique ID of the resource that the metafield is attached to.

owner_resource

{ "owner_resource" : "shop" }

The type of resource that the metafield is attached to.

value

{ "value" : "25" }

Information to be stored as metadata.

Minimum length: 1 characters. Maximum length: 80000 characters.

value_type

{ "value_type" : "integer" }

States whether the information in the value is stored as a 'string', 'integer' or 'json'.


Metafield types

Each metafield and metafield definition has a value_type, which defines the type of information that it can store.

When using the API to read and write metafields, the value is always entered and stored as a string, regardless of value_type.

Metafields and definitions can have the following value types:

Value type

Description

Example value

string

A text field.

{"value": "This item contains dairy products."}

integer

A whole number in the range of +/-9,007,199,254,740,991.

{"value": "10"}

json

A JSON-formatted string.

{"value": "{\"price\":10000,\"stock\":\"instock\",\"meta\":[{\"k\":\"v1\"},{\"k\":\"v2\"}]}"}
