Attentive Identity API is one of 19 APIs that [Attentive](https://apis.io/providers/attentive/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Identity. The published artifact set on APIs.io includes an OpenAPI specification.

Use the Identity API to manage user identifiers. With this API, you can programmatically add a client user identifier or custom identifier(s) to a user. You should only use clientUserId and customIdentifiers to send Attentive your system-assigned unique identifiers (even when testing). Notes: - Sending duplicate values could lead to unintentionally bridging users together. - Don't use customIdentifiers to send attributes (e.g., first name, last name). To send those types of attributes, use our [Custom Attributes API](https://docs.attentivemobile.com/openapi/reference/tag/Custom-Attributes/). - Avoid sending null values or empty strings. If you don't have a valid identifier, you should omit the field from the payload.
