# Energy Transfer Equity, L.P.

> Energy Transfer Equity, L.P. (NYSE: ETE) was a master limited partnership that
> owned and operated a diverse portfolio of midstream energy assets — natural gas
> gathering, processing, transportation and storage, NGL and crude pipelines, and
> retail fuel. In October 2018 ETE merged with its operating subsidiary Energy
> Transfer Partners, L.P. to form a single publicly traded partnership, Energy
> Transfer LP (NYSE: ET). ETE no longer exists as a separate registrant and
> publishes no API, developer portal, or machine-readable contract of its own.
> Every developer resource that once sat under the ETE umbrella — including the
> Messenger+ portal for pipeline messaging, nominations and gas scheduling — is
> now published under the Energy Transfer LP brand.
