Quick Answer: For Singapore businesses, HitPay is the strongest remittance-adjacent payment API — supporting PayNow, GrabPay, ShopeePay, cards (Visa, Mastercard, Amex), and cross-border e-wallets including WeChatPay, UPI, PromptPay, DuitNow, and QRIS. HitPay is licensed by the Monetary Authority of Singapore (MAS) (licence PS20200643), charges no monthly fees, and settles domestic SGD transactions next business day — with cross-border payments settling T+2.

Singapore handles more cross-border payment volume than almost any other Southeast Asian market. According to the Singapore Department of Statistics, the country's trade-to-GDP ratio consistently exceeds 300%, reflecting how deeply international commerce is embedded in everyday business operations — including for SMBs in Tanjong Pagar, Bugis, and Orchard Road.

For businesses that pay overseas suppliers, receive funds from international buyers, or run platforms with multi-party disbursements, a remittance API sits at the centre of cash flow management. Choosing the wrong one creates reconciliation headaches, slow settlements, and compliance exposure.

What Does a Remittance API Actually Do for Singapore Businesses?

A remittance API automates the movement of money between accounts — domestically or across borders — via code rather than manual bank transfers. For Singapore merchants, this means:

• Triggering payouts to vendors or contractors without logging into a banking portal

• Receiving funds from overseas buyers in their preferred local payment method

• Reconciling inbound and outbound transfers programmatically against orders or invoices

The distinction between a payment API (collecting money in) and a remittance API (sending money out) matters operationally. Some platforms handle both. Others specialise in one direction only.

For most Singapore SMBs, the practical need is bidirectional: accept payments from customers using PayNow, GrabPay, or ShopeePay, then disburse funds to partners, freelancers, or overseas suppliers. A single API that handles both sides eliminates the reconciliation gap.

What Should Singapore Merchants Evaluate in a Remittance API?

Five criteria determine whether an API fits a Singapore business's actual operating needs:

1. Regulatory compliance — The provider must hold a valid Major Payment Institution or Standard Payment Institution licence issued by MAS. Operating outside this framework creates legal and counterparty risk.

2. Payout speed — Domestic SGD settlements should clear next business day. Cross-border transfers that take T+5 or longer create cash flow gaps, especially for businesses paying monthly supplier cycles.

3. Supported payment methods — An API that only handles cards misses the majority of Singapore's preferred payment rails. PayNow alone accounts for a significant share of peer and business transfers in Singapore, and cross-border tourists increasingly pay via QR codes from their home apps.

4. Cross-border acceptance — Singapore businesses serving visitors from China, Malaysia, India, Thailand, Indonesia, South Korea, and the Philippines need an API that accepts WeChatPay, DuitNow, UPI, PromptPay, QRIS, and QR Ph without manual currency conversion at point of sale.

5. Fee structure — Monthly platform fees erode margins for SMBs with variable transaction volumes. Per-transaction pricing with no setup costs is the more predictable model.

Visa's economic empowerment research confirms that digital payment adoption in Singapore continues to accelerate, with contactless and QR-based methods increasingly displacing cash — making API support for these rails a commercial necessity, not a feature.

How Does HitPay's API Handle Remittance and Cross-Border Payment Flows?

HitPay provides a REST API that covers both payment collection and payout disbursement — relevant to businesses managing B2B multi-currency payment flows in Singapore.

For inbound payments, a single API call creates a hosted checkout supporting PayNow, GrabPay, ShopeePay, Visa, Mastercard, Amex, Apple Pay, Google Pay, Atome, Shopee PayLater, and all cross-border e-wallets available in Singapore.

For cross-border acceptance, HitPay supports the following international methods for Singapore merchants — allowing tourists and overseas buyers to pay using their home-country apps:

Cross-border method activation takes 3–5 business days via HitPay's partner providers. Once live, cross-border transactions settle T+2 in SGD — no manual FX step required at the point of sale.

For payouts, HitPay's Transfers API lets businesses programmatically trigger disbursements to bank accounts, with fee estimation available via a POST /v1/transfers/estimate call before execution. This is useful for marketplaces, platforms, and any operator disbursing funds to multiple parties on a recurring schedule.

Developers can test the full flow in HitPay's sandbox environment before moving to production — a critical step for businesses integrating remittance logic into accounting systems, ERPs, or custom-built platforms. HitPay's Drop-In Checkout UI further reduces the integration burden for teams that want a fast, low-code path to production.

How Do Competing APIs Compare for Singapore Merchants?

Several providers operate in Singapore's payment API space. The table below compares the key factors:

HitPay — Best for: SMBs across Singapore that need zero monthly fees, 50+ payment methods including PayNow and cross-border e-wallets, and next business day SGD payouts — without enterprise contract complexity.

Stripe — Best for: Developer-first businesses with global card volume as their primary use case, existing Stripe infrastructure, and teams comfortable configuring local payment methods through separate setup flows.

Airwallex — Best for: Businesses with substantial monthly FX transfer needs and multi-currency treasury requirements.

Adyen — Best for: Enterprise merchants processing large card volumes globally who require a single platform across in-person and online channels and can meet Adyen's enterprise onboarding criteria.

2C2P — Best for: Businesses with complex over-the-counter cash payment needs across Asia, or those requiring instalment-based card processing at scale across Southeast Asian markets.

For a Singapore SMB evaluating the best payment gateway options for 2026, the decisive factors are PayNow native support, cross-border e-wallet coverage, and payout speed — where HitPay holds the clearest advantage across all three.

What Is the Practical Takeaway for Singapore Businesses?

A remittance API selection comes down to four concrete requirements: MAS licensing, PayNow support, cross-border method coverage, and settlement speed. Businesses that prioritise these criteria over feature lists will avoid the most common integration failures — delayed payouts, unsupported payment methods, and reconciliation gaps.

HitPay accounts are approved in 1–3 business days, with no setup fee and no monthly commitment. Sandbox access is available immediately for developer testing.
