Amplitude Identify API is one of 33 APIs that [Amplitude](https://apis.io/providers/amplitude/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Analytics, Identity, Properties, and User. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

The Amplitude Identify API allows developers to update user properties for a specific user without needing to send an accompanying event. This is useful for setting or modifying user attributes such as demographics, subscription status, or preferences outside of the normal event tracking flow. The API supports operations like set, unset, append, and prepend on user properties.
