Nepal's capital market is evolving rapidly, and institutional players, wealth-tech startups and diaspora-focused fintech teams increasingly need programmatic access to the same data flows that retail investors use through mobile apps. IPO Bulk Apply - NEPSE & IPO is one of the most feature-rich investment utilities on the Nepali market, combining bulk IPO submission, real-time NEPSE market data, MeroShare portfolio sync and CDSC allotment tracking in a single Android and iOS application.
OpenFinance Lab converts those in-app data flows into documented, server-side APIs — clean REST and WebSocket endpoints that banks, broker dashboards, accounting platforms and personal-finance products can integrate without building raw protocol adapters themselves. Whether your team needs to orchestrate IPO submissions across dozens of DEMAT accounts, fan allotment results into a notification pipeline, or stream live NEPSE floorsheet data into a surveillance system, the IPO Bulk Apply API integration service provides a production-ready foundation under SEBON-aligned compliance guardrails.
This guide covers what the API supports, the real-world use cases it unlocks, and why teams across Nepal, India, the UAE and the broader Nepali diaspora are choosing OpenFinance Lab to accelerate their NEPSE integration work.
============================
SUPPORTED API FEATURES
--------------------
The IPO Bulk Apply NEPSE API integration surfaces several distinct data domains from the upstream MeroShare, CDSC and NEPSE NOTS/TMS sources. Each feature below reflects a real data contract that has been mapped, validated and documented by the OpenFinance Lab team:
• Bulk IPO Submission API
Submit IPO applications across many MeroShare DEMAT accounts in a single API call. Each submission returns per-account status codes, CRN references and ASBA debit identifiers, making reconciliation against bank records straightforward.
• IPO Allotment Result API
Pull allotment results directly from the CDSC portal and surface them as structured rows with allotted, not_allotted and pending states, tied to each applicant's BOID and company symbol.
• NEPSE Live Market Data API
Access real-time NEPSE index values, top gainers and losers, per-symbol bid/ask prices, market depth snapshots and historical close prices through REST endpoints and low-latency WebSocket feeds.
• Floorsheet Export and Webhook Subscriptions
Subscribe to per-trade floorsheet rows filtered by symbol or minimum quantity. Each event delivers buyer and seller broker IDs, quantity, price and transaction ID within seconds of NEPSE publication.
• Portfolio and MeroShare Sync API
Ingest MeroShare CSV exports and TMS Excel sheets, normalize holdings against the NEPSE master symbol list and compute weighted average cost, current value and unrealised profit/loss ready for wealth-tech or accounting output.
• Broker Ranking, Dividend Tracker and Price Alert Webhooks
Access broker performance rankings, monthly turnover stats, dividend and bonus event data per company and configurable price-alert webhooks, giving your product complete coverage of the IPO Bulk Apply feature set.
============================
USE CASES & APPLICATIONS
--------------------
[1] MULTI-ACCOUNT IPO SUBMISSION DESK
------------
Family offices, share-management consultancies and regulated investment advisors that manage IPO applications for multiple clients are the primary buyers of this integration. The API accepts a list of BOID, bank ID and unit count combinations, authenticates each into MeroShare with encrypted stored credentials, posts the application and reconciles against the bank's ASBA debit record.
• Tenant-aware backend for managing dozens of DEMAT accounts simultaneously
• Parallel submission fan-out with per-account status tracking
• Audit log suitable for regulated client reporting
• Specific error surfacing for ASBA_INSUFFICIENT, BOID_INACTIVE and ISSUE_CLOSED events
• Mirrors the batch-apply behaviour of open-source tools like nepseutils with enterprise-grade logging
[2] ALLOTMENT NOTIFICATION MICRO-SERVICE
------------
The CDSC allotment portal publishes results per company on a schedule tied to each issuer. This integration polls the CDSC endpoint, normalises results into a consistent schema and fans them back to MeroShare BOIDs so your notification pipeline — whether webhook, SMS gateway, Telegram bot or email — receives structured allotment data within seconds of publication.
• Automated CDSC polling with jitter to avoid portal pressure during peak result windows
• Normalised allotted / not_allotted / pending schema per BOID
• Webhook delivery to any HTTPS endpoint with HMAC signature verification
• Supports notification fan-out for investor-facing apps, broker portals and family office dashboards
• Full audit trail of every allotment fetch for regulator response
[3] WEALTH DASHBOARD WITH PORTFOLIO SYNC
------------
Nepali professionals abroad need a consolidated view of their domestic holdings. The portfolio sync endpoint accepts a MeroShare CSV or TMS Excel file, normalises symbols against the NEPSE master data set and computes returns against the live index. Consent is captured once and refreshed via OAuth-style token rotation, following the same OpenFinance pattern used for bank-statement aggregation in other markets.
• POST /portfolio/import accepts both MeroShare CSV and TMS Excel formats
• Automatic symbol normalisation against live NEPSE master list
• Dividend, bonus and share-split event normalisation for accurate WACC computation
• Ready-to-export output for accounting, tax preparation and family-office reporting
• Designed for Nepali diaspora in the UAE, Australia, the UK and the US
[4] BROKER COMPLIANCE AND SURVEILLANCE FEED
------------
NEPSE's TMS exposes per-broker fill data through the connectIPS payment gateway integration. This scenario converts raw fill events into a streaming feed of trades, settlement events and collateral movements that compliance teams can replay into surveillance tooling to detect wash trades, layering and unusual cross-symbol activity around IPO listings.
• Real-time broker fill data stream from NEPSE NOTS/TMS
• Per-trade records with buyer broker ID, seller broker ID, quantity and price
• Filterable by symbol, broker or minimum trade size via webhook subscription
• Structured output compatible with standard surveillance and risk platforms
• Rate limits and back-off tables calibrated per upstream system to maintain stable access
[5] CROSS-BORDER INVESTOR DATA ROOM
------------
Diaspora investors in the UAE, Australia and the US increasingly hold Nepalese shares but lack a single consolidated view of their IPO history, current holdings, dividends and bonus share events. This integration provides a single OAuth-protected API that consolidates all those data domains into one canonical JSON structure, ready for Plaid-style aggregation into expat-focused budgeting and tax tools.
• Unified endpoint covering IPO history, holdings, dividends and bonus shares
• OAuth-protected with per-tenant credential isolation
• AES-256-GCM encrypted credential vault with per-call decryption
• Canonical JSON schema ready for integration into budgeting, tax and wealth apps
• Supports investors across Nepal, India, UAE, Australia, UK and US

BENEFITS & ADVANTAGES
--------------------
✓ Production-Ready Source Code Delivery
Every engagement ships runnable Python (FastAPI) and Node.js (Fastify) reference servers, an OpenAPI 3.1 specification, a Postman collection and a pytest/Jest test suite with fixtures — not a slide deck or a generic wrapper.
✓ SEBON-Aligned Compliance Architecture
The integration is built against authorized or documented public endpoints only. Compliance memos covering SEBON, CDSC and NEPSE redistribution boundaries are included with every delivery, and commercial market-data redistribution requirements are flagged before build starts.
✓ AES-256 Encrypted Credential Management
DEMAT credentials and PINs are stored in an envelope-encrypted vault with per-tenant KMS keys. Only adapter pods can request per-call decryption, ensuring that PII like BOID and bank account numbers stays protected at rest and in transit over TLS 1.3.
✓ Multi-Account Orchestration at Scale
The bulk submission architecture models each DEMAT account as a separate tenant, fans out submissions in parallel and reconciles allotment results back into a single ledger — the highest-value capability for family offices and share-management consultancies running IPO desks for many clients.
✓ Pay-After-Delivery Pricing Model
Source-code delivery starts from $300. Payment is due after delivery upon satisfaction, removing upfront financial risk for early-stage fintech teams exploring NEPSE integration for the first time.
✓ Pay-Per-Call Hosted Option Available
Teams that prefer usage-based access can reach OpenFinance Lab's hosted endpoints over HTTPS with API-key and HMAC signature authentication, paying only per call for IPO submission, allotment lookup and floorsheet pulls — no upfront cost and no infrastructure to manage.
✓ Fast Delivery Timeline with Transparent Scope
Most first deliveries land in 5 to 12 business days. The engagement starts with a scope confirmation, moves through protocol analysis and API design, then build and internal validation, with documentation and sample apps delivered in the final window. CDSC or broker approvals that extend timelines are flagged on day one.

IPO Bulk Apply - NEPSE & IPO represents one of the most comprehensive retail investment utilities available in the Nepali market, and the data flows it exposes — bulk IPO submission, CDSC allotment results, real-time NEPSE prices, MeroShare portfolio sync and broker analytics — are exactly the signals that fintech teams, family offices and diaspora-focused wealth products need in programmatic form.
OpenFinance Lab's IPO Bulk Apply NEPSE API integration service bridges that gap with production-ready source code, a SEBON-aligned compliance architecture and a pricing model that lets you pay after delivery. Whether you are building a multi-account IPO submission desk for a regulated client base, a Plaid-style aggregation product for Nepali investors abroad, or a broker compliance surveillance feed, the integration covers the full NEPSE and MeroShare data stack from a single engagement.
Teams exploring similar data needs from neighbouring apps in the Nepali ecosystem — including MeroShare, ShareSansar, MeroLagani, NEPSE Alpha, Nepalytix, Mr NEPSE Bulk IPO Checker, NepseFolio, Sastoshare and Share Alpha NEPSE IPO AI — can reuse the same integration toolkit, since all of those apps draw from the same upstream CDSC, NEPSE and TMS sources.
