# Test JSONata expression

`POST /api/orders/expressions/jsonata`

This endpoint allows you to test a JSON document with a JSONata expression, returning `true` if the document meets the criteria posed in the expression, or `false` if it does not.


Since JSONata expressions can be used to filter order updates in the [Orders API feed and hook](https://developers.vtex.com/docs/guides/orders-feed), this endpoint can be used to test an expression's results before configuring the [feed or hook](https://developers.vtex.com/docs/guides/orders-feed).


Learn more about how to use JSONata expressions, in the [JSONata documentation](https://docs.jsonata.org/overview.html).
