BKASH MERCHANT API INTEGRATION
============================================================
Turn bKash Merchant payment events, the 30-day ledger and monthly statements into a live feed for your own systems.
--------------------
INTRODUCTION
--------------------
bKash Merchant is the acceptance and bookkeeping app behind millions of merchant accounts in Bangladesh's mobile financial services (MFS) ecosystem. Every QR scan, counter payment or send-money transaction that lands in a merchant's bKash account triggers an instant notification, a voice prompt, and a new row in a rolling 30-day ledger — but until now, that data has stayed locked inside the app. A bKash Merchant API integration changes that. By mapping the authorized protocol behind the app's traffic, an integrator can pull merchant payments, transaction summaries, account statements and real-time payment alerts directly into a POS, ERP, accounting tool or reconciliation pipeline — all under the merchant's own consent. For Bangladesh businesses, accountants and fintech platforms, this kind of bKash Merchant integration closes the gap between "money arrived" and "your system knows it arrived."
--------------------
SUPPORTED API FEATURES

Live payment capture — pull the latest merchant transaction (amount, charge, transaction ID, reference) the moment it posts
Rolling 30-day transaction ledger — programmatic access with in / out / counter filtering for reconciliation
Daily and monthly transaction summaries — counts, amounts, fees and balance in one normalized feed
Account statement retrieval — both the auto-emailed monthly statement and on-demand periodic statements
Transaction limit checks — daily and monthly per-service limits with used count and amount, for pre-payout validation
Real-time webhook bridge — instant and voice payment notifications re-emitted as HTTP callbacks to your endpoint
Secure session handling — merchant-number, OTP and PIN handshake mapped with automatic token refresh

SUBSCRIPTION PLANS
--------------------
Two engagement models are available depending on how you want to run this integration:
Source-code delivery — from $300, includes runnable API source (Python or Node.js), OpenAPI spec, automated tests and documentation; payment due only after delivery and your approval
Hosted API, pay-per-call — no upfront fee, billed only for the calls you actually make, ideal for teams that want to skip the build entirely
--------------------
CONCLUSION
--------------------
The real value inside bKash Merchant isn't the app interface — it's the payment event itself, the 30-day ledger behind it, and the statements that summarize it. A properly authorized bKash Merchant API integration turns those surfaces into a feed your own POS, ERP or accounting system can act on automatically, without anyone watching a phone screen. Whether you need a one-time statement parser or a fully live webhook-driven sync, the work starts with mapping what the app already shows a consenting merchant.
