How this service works
Build a Thai PromptPay QR payment payload (EMVCo / Thai QR Payment text) for a mobile number, 13-digit national ID or tax ID, or e-wallet ID, with an optional amount in baht. Checks the ID checksum and adds the CRC. Render the payload as a QR code and any Thai banking app can pay it. Query: ?id=0812345678&amount=150
Output
Returns the EMVCo-compliant PromptPay QR payload string with CRC checksum, plus a rendered QR code image that any Thai banking app (SCB, Kbank, BBL, etc.) can scan and process as a payment.
Example use cases
E-commerce checkout QR for customer
“Create a PromptPay QR code for 299.50 baht linked to my mobile number 0891234567 so my customer can scan and pay via their Thai banking app.”
Reusable QR for donation page
“Generate a reusable PromptPay QR with no fixed amount for Thai national ID 1234567890123 — I want donors to enter their own amount when scanning.”
Invoice payment request for business
“Make a PromptPay QR payment payload for tax ID 0105556123456 for 12500 baht so my client can pay the invoice using SCB or Kbank app.”

Endpoint
GEThttps://api.thaikit.dev/promptpay?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically generate a Thai PromptPay QR payment payload for mobile payments, invoicing, e-commerce checkouts, or donation flows within Thailand. It is purpose-built for the Thai EMVCo standard with built-in checksum validation, making it more reliable than generic QR generators that do not understand PromptPay encoding rules.
Side effects
- Invalid PromptPay ID format (wrong length or non-numeric) returns an error
- ID checksum validation failure (e.g. malformed national ID) returns rejection
- Amount exceeds allowed decimal precision or is negative
- Missing required 'id' query parameter returns 400 error
- Non-Thai ID format not recognized by the system
