Solutions · API & Integration

One API. All of Asia.

Collections, payouts, statuses and settlement through a single REST API — integrate once, and new markets arrive without code changes.

1 · Get sandbox access

Credentials and full documentation arrive with onboarding.

2 · Build

REST endpoints and signed webhooks, with integration engineers on call.

3 · Test

Simulate every payment state in the sandbox before a single real transaction.

4 · Go live

Switch on the markets you need. Typical integrations complete in days.

What the API covers

  • Deposits — create payment sessions, receive QR/bank/wallet instructions, get real-time status
  • Payouts — single and batch disbursements with validation and status tracking
  • Webhooks — signed, idempotent event callbacks for every state change
  • Reporting — transactions, settlement and reconciliation data on demand

What a payment event looks like

POST https://your-server.com/webhooks/help2pay
{
  "event": "deposit.completed",
  "transaction_id": "h2p_9f8a7b6c",
  "merchant_ref": "ORDER-10482",
  "market": "TH",
  "method": "promptpay",
  "currency": "THB",
  "amount": "1500.00",
  "completed_at": "2026-06-11T14:02:11+07:00",
  "signature": "t=1760162531,v1=5f1d..."
}

Illustrative example — full schemas, signing details and endpoint references are provided with sandbox access.

Engineering principles

  • Idempotent by design — retries are always safe
  • Signed everything — webhook payloads are verifiable end to end
  • 99.9% uptime — monitored around the clock
  • Stable contracts — new rails and markets are added platform-side; your integration doesn't change
