Transco Nominations API

The Transco Nominations API enables natural gas shippers to submit, modify, and track pipeline transportation nominations on the Transco pipeline system via the 1Line electronic bulletin board portal. Nominations define the quantity of gas a shipper wants to transport, the points of injection and withdrawal, and the scheduling period. The system supports online screen entry, flat file uploads, and EDI-based nomination submission.
