# DiDi (DiDi Global)

> DiDi Global is a mobility technology platform (ride-hailing, taxi, and enterprise travel). This profile covers DiDi's public developer surface: the DiDi Enterprise Services (DDES) Open API for enterprise employee-travel management, base URL https://api.es.xiaojukeji.com, documented at https://opendocs.xiaojukeji.com/version2024. Authentication is OAuth 2.0 client_credentials plus per-request signing (MD5/SHA256) and an optional AES payload encryption, with a required IP allow-list. Official Java and Go SDKs are published under the github.com/didi organization. This is an API Evangelist catalog profile, not an official DiDi document.
