PAOTANG () API INTEGRATION
============================
Reach every wallet inside Krung Thai's Paotang super-app through one consented, authorized data channel
--------------------
INTRODUCTION
--------------------
- Paotang, published by Krung Thai Bank, is not a single wallet — it is at least six distinct server-side ledgers bundled into one super-app: the Paotang Pay open wallet, the government G-Wallet, the . savings-bond wallet, the corporate-debenture () wallet, a linked view over up to three Krungthai bank accounts, and a Krungthai consumer-loan line. For fintech teams, accounting platforms, wealth dashboards and lenders operating in Thailand, this breadth is exactly what makes Paotang worth integrating — and exactly why a naive scrape falls apart. OpenBanking Studio maps each ledger separately and delivers a Paotang API integration built on authorized protocol analysis and consented access, so wallet balances, PromptPay transfers, savings-bond holdings, debenture positions, loan schedules and G-Wallet activity all arrive as clean, normalized data instead of a tangled export.
--------------------

BENEFITS & ADVANTAGES
--------------------
Reaches all six Paotang ledgers through one consented integration, not a patchwork of partial pulls
Wallet isolation keeps government G-Wallet activity from contaminating ordinary payment data
Unit-level bond reconciliation catches partial fills instead of trusting a single balance read
Device-binding and token-refresh handling designed around the app's real session behavior
Delivered as an OpenAPI specification with normalized schemas ready for integration
Runnable source in Python or Node.js, with automated tests against recorded fixtures
Built legal-by-design under PDPA consent, forward-compatible with Thailand's incoming "Your Data" rule
--------------------
SUBSCRIPTION PLANS
--------------------
Two engagement models are available. Buy the runnable API source outright starting at $300 — this includes the specification, tests and documentation, payable after delivery once it works for you. Alternatively, call hosted endpoints on a pay-per-call basis with no upfront cost, ideal for a pilot focused on a single feed such as wallet statements or PromptPay transfers. A typical build runs 1–2 weeks from the point wallet scope is agreed.
--------------------
CONCLUSION
--------------------
Paotang's value lies in its breadth — wallet, PromptPay, savings bonds, debentures, loans and government entitlements all under one app — but that same breadth is what makes an authorized, wallet-aware integration essential rather than optional. Whether the goal is accounting automation, a wealth dashboard, credit underwriting or welfare reconciliation, a properly mapped Paotang API integration turns six separate ledgers into one dependable data feed. Reach out to scope the wallets that matter for your project and get a working integration in weeks, not months.
