Get SASM ID List

Retired — no longer supported

The Get SASM ID List interface was removed with the RTC+B implementation on 12/05/2025. SASM no longer exists as a separate market process, SASM is no longer a valid MarketType, and ERCOT no longer accepts this request.

This page is retained for reference when interpreting data retrieved before that date. The field tables below describe the pre-RTC+B interface.

The purpose of this interface is to provide the means to request that ERCOT send a list of SASM Market IDs for a given trading date. The following table describes the request parameters:

Message Element	Value
Header/Verb	get
Header/Noun	SASMIDList
Header/Source	Market participant ID
Header/UserID	ID of user
Request/TradingDate	Trading Date

The corresponding response messages would use the following message fields:

Message Element	Value
Header/Verb	reply
Header/Noun	SASMIDList
Header/Source	ERCOT
Reply/ReplyCode	Reply code, success=OK, error=ERROR
Reply/Error	Error message, if error encountered
Reply/Timestamp	Identifies current ERCOT local time
Reply/ID	SASM IDs found for the requested Trading Date Format: YYYYMMDDHHMMSS
