To get started with the API you have a couple options:
You can choose to use one of the Xente supported SDKs or Integrate the API manually in your choice of language.
To use one of the SDKs check for you language in the “references list” in the sidebar. If you instead want to use a language that does not have a Xente supported SDK, a custom implementation should be trivial as the platform uses standard HTTP which is widely supported.
