The Account opening API is a technical integration / interface between the Participant and NSDL for opening instant demat account, which will be initiated from Participant’s application to NSDL Insta Interface System. The account opening feed sent from Participant will be received at NSDL Insta Interface and would be then transmitted to the NSDL’s depository system (NDS). Post activation of the account at NSDS, Participants will receive the feed at their Local DPM System / Cloud DPM System, as the case may be, for back office updation.
