All clearing members must migrate to NCMS API 2.0 facility, which is now available in the live environment. Members need to register by providing specific details to msd_clearing@nsccl.co.in to access the new API facility.

Key Points

  • NCMS EXE will be decommissioned on April 06, 2026
  • NCMS API version 1.6 will be decommissioned on February 23, 2026

Regulatory Changes

This circular mandates a technology infrastructure upgrade for all clearing members in the F&O segment. The existing NCMS EXE application and older API version 1.6 are being phased out in favor of the more advanced NCMS API 2.0 platform.

Compliance Requirements

  • Members must send registration email to msd_clearing@nsccl.co.in with the following details:
    • Primary Member Code
    • Member Name
    • Email ID (Group ID preferred)
    • Contact Number
    • IP Address(es) from which API requests will be sent
  • Members are required to extensively test the NCMS API 2.0 in their environment

Impact Assessment

This technology upgrade has high operational impact on all clearing members in the F&O segment. Members must allocate resources for:

  • Testing and integration of NCMS API 2.0 into their existing systems
  • Training staff on the new API facility
  • Ensuring business continuity during the migration period
  • Updating internal systems and workflows to accommodate the new API structure

Failure to migrate before the decommissioning deadlines could result in disruption of clearing operations for F&O trades. Members have approximately 2-4 months to complete testing and migration depending on which system they are currently using.

Impact Justification

Critical technology migration affecting all F&O clearing members with mandatory deadlines for system transition
