# Conditional metafields APIs

As of `2024-07`, we've added APIs for viewing and filtering conditional metafield definitions such as product attributes:

* Use the `constraints` field on `MetafieldDefinition` to view the metafield definition's constraints.
* Use the `constraintSubtype` argument on the `metafieldDefinitions` and `standardMetafieldDefinitionTemplates` queries to retrieve only metafield definitions that apply to the passed constraint subtype.
* Use the `constraintStatus` argument on the `metafieldDefinitions` and `standardMetafieldDefinitionTemplates` queries to filter based on whether the metafield definitions are constrained.
