8. 3 rd Party Registration & Account Management AMWG Change Request 016 Capability for RORs to Grant Access to SMT APIs and SMT FTPS to Vendors on Their Behalf

9. 3 rd Party Registration & Account Management 9 API & FTP Access to Multiple Entities - Requirements  Ability for the REPs to allow API access for unlimited multiple entities in addition to retaining their own access, with appropriate approval mechanism.  Ability for the REPs to allow FTP access for multiple entities in addition to retaining their own access, with appropriate approval mechanism.  Background - –These multiple entities are typically Billing, EDI or Demand Response partners working on behalf of the REPs. –Currently only one entity can have access to API and FTP of one DUNS entity

10. 3 rd Party Registration & Account Management 10 Solution Approach  API Access –Each entity uses its own security certificate –ROR creates a portal user (non-admin) for the new entity –SMT shares ROR’s API account access details to the new entity –SMT works with the new entity to configure and accomplish integration  FTPS Access –Each entity uses its own security certificate –SMT enables additional FTP access for the new entity on the existing FTPS account and shares the details –SMT works with the new entity to configure and accomplish integration –ROR has to share their PGP decryption key to new entity This is the least effort and less resource consuming alternative. The other option is to create a new FTP account for new entity with their own PGP key, however it will require the files to be processed twice and a duplicate copy of the files with separate encryption to be stored at FTPS which requires processing power as well as space. –SMT restricts DELETE permission to all FTP accounts, to avoid deletion of files by one entity while the other has not downloaded it. The deletion will be performed by SMT as per the 10 days retention rule. There will be minor storage impact to retain more files as the immediate deletion that some entities are doing currently will be stopped.

13. 3 rd Party Registration & Account Management 13 Pre-Requisites from RORs / New Entities  API Access – Certification Authority (CA) signed security certificate – ROR to create a non-admin portal user under them  FTP Access –Certification Authority (CA) signed security certificate –ROR to share their PGP decryption key to new entity –SMT will restrict DELETE permissions on FTPS server, this may cause a few ROR’s FTPS scripts to fail/throw errors if they try to delete files after downloading. Those scripts need to be modified to avoid such errors.
