# Metafield Types

Metafield types let you specify which value you're going to store to simplify the validation and display.
YouCan Metafields API currently support the following types:

Each of the types mentioned above supports a list type (`list.{type}`), as an example `list.number` can store a list of numbers (`[3, 4, 2, 12, 123]`).

**Note:** All values are stored as strings internally and cast using the selected type on display.
