UID2 Endpoints: Summary

All UID2 endpoints require a client secret for encrypting API requests (except POST /token/refresh requests) and decrypting responses. For details, and code examples in different programming languages, see Encrypting Requests and Decrypting Responses.

UID2 Tokens

The following endpoints are for retrieving and managing UID2 tokens (identity tokens, advertising tokens), and are used mainly by publishers.

Endpoint	Description	Request Encryption	Response Decryption
POST /token/generate	Requests a UID2 token from an email address or phone number provided by a user with their authorization for UID2-based targeted advertising. If the DII is valid, and the user has not opted out of UID2, this operation returns a UID2 token and associated values.	Required	Required
POST /token/validate	Used for testing, to validate that an advertising token (UID2) matches the specified email address, phone number, or the respective hash.	Required	Required
POST /token/refresh	Generate a new token for a user for their refresh token from the POST /token/generate response.	N/A	Required
