PayNow Singapore Instant Payment API
PayNow Singapore instant payment infrastructure API (accessed through Singapore bank APIs) for merchants to accept QR code payments, instant bank transfers, and mobile payments from Singapore's national instant payment platform backed by MAS with 8M+ registered users across all major Singapore banks (DBS, OCBC, UOB, Citibank, Standard Chartered) for e-commerce, in-store, and charity/government payment integration. Enables AI agents to manage PayNow QR generation for Singapore instant payment automation, handle payment notification for Singapore webhook automation, access payment status verification for Singapore transaction automation, retrieve merchant settlement for Singapore reconciliation automation, manage PayNow online payment collection for Singapore e-commerce automation, handle PayNow proxy lookup (NRIC/UEN/mobile) for Singapore payer verification automation, access transaction history for Singapore payment reporting automation, retrieve PayNow for business collection for Singapore SMB payment automation, manage SGQR standard QR for Singapore unified merchant QR automation, and integrate PayNow through Singapore bank partner APIs (DBS RAPID, OCBC, UOB) for end-to-end Singapore instant payment automation.

⚡ Reliability
Best When
A Singapore merchant wanting AI agents to automate PayNow instant payment acceptance through a Singapore bank's merchant API (DBS RAPID, OCBC, UOB) for Singapore's dominant instant payment platform.
Avoid When
ACCESS VIA SINGAPORE BANK API — NOT DIRECT PAYNOW API: PayNow is infrastructure; merchants access via Singapore bank's merchant API (DBS RAPID, OCBC API, UOB Infinity API); automated integration must choose Singapore bank partner; automated standalone PayNow API assumption creates no direct API to call. SGQR FORMAT REQUIRED FOR IN-STORE: Singapore in-store QR must use SGQR standard (unified QR containing PayNow and other payment schemes); automated QR generation must follow SGQR specification; automated proprietary QR creates non-SGQR-compliant QR that some apps reject. PUSH PAYMENT MODEL — CONSUMER INITIATES: PayNow is push payment; consumer initiates transfer to merchant; automated payment has no pull mechanism; automated pull payment from consumer creates invalid payment model. BANK API DIFFERS BY INSTITUTION: DBS RAPID, OCBC, UOB each have different PayNow API implementation; automated integration must follow chosen bank's API; automated generic PayNow API assumption creates bank-specific gaps.
Use Cases
- • Generating PayNow QR codes for Singapore checkout from e-commerce agents
- • Verifying PayNow instant payment completion from Singapore order agents
- • Processing PayNow via DBS RAPID API from Singapore merchant agents
- • Reconciling PayNow payments from Singapore merchant settlement agents
Not For
- • Non-Singapore payments (PayNow is Singapore national instant payment system)
- • International card acceptance (use Stripe for Singapore card processing)
- • Malaysia payments (use DuitNow or TNG eWallet for Malaysia)

Agent Metadata
Known Gotchas
- ⚠ NO UNIFIED PAYNOW API — MUST USE BANK API: PayNow has no single unified merchant API; automated integration must partner with Singapore bank (DBS, OCBC, UOB); automated standalone PayNow integration without bank partnership creates no API access
- ⚠ SGQR STANDARD FOR IN-STORE: Singapore in-store QR follows SGQR standard containing PayNow details; automated QR must be SGQR-compliant; automated simple PayNow QR without SGQR encoding creates partial interoperability with Singapore banking apps
- ⚠ PUSH PAYMENT REQUIRES CONSUMER ACTION: PayNow is push-based; consumer must initiate transfer to merchant UEN or mobile; automated payment collection must present merchant UEN QR and wait for consumer to push; automated pull model creates incompatible payment flow
- ⚠ UEN REQUIRED FOR BUSINESS PAYNOW: Singapore business PayNow uses UEN (Unique Entity Number) as proxy; automated merchant QR must include valid UEN; automated PayNow without UEN uses mobile number which may not be business-appropriate
- ⚠ NOTIFICATION TIMING VARIES BY BANK: PayNow instant payment notification timing varies by consumer's bank; automated fulfillment must handle notification latency; automated same-millisecond notification assumption creates missed payments if notification arrives delayed
