aid: worldfirst url: https://raw.githubusercontent.com/api-evangelist/worldfirst/refs/heads/main/apis.yml name: WorldFirst kind: company description: >- WorldFirst is a United Kingdom-founded cross-border payments and money-movement company, headquartered in London and owned by Ant Group (Alipay) since 2019. It gives online sellers, marketplaces, and SMEs a multi-currency World Account to collect, hold, convert, and send money across borders, alongside a World Card for multi-currency spending and marketplace/supplier payouts. Its home market is the United Kingdom, but its book is global e-commerce and cross-border trade, serving merchants selling on Amazon and other marketplaces. WorldFirst ships a genuine, API-native developer platform at developers.worldfirst.com built on Ant Group's Antom-style gateway (open-sea/open-eu/open-na hosts, /amsin/api/v1 paths): a RESTful, JSON, HTTPS-only interface segmented into an Enterprise Solution (account, beneficiary, FX, transfer, payout, invoicing, virtual-card credit), a Pay Solution (Cashier Payment / online checkout acceptance for merchants), and a WorldTrade Solution (cross-border trade orders). Requests are secured with RSA256/ECC224 digital signatures plus OAuth 2.0 access tokens; asynchronous notifications (webhooks) return payment and trade-order results. The public reference is documentation-and-console only — the underlying OpenAPI/Swagger is not offered as a downloadable spec (the gateway blocks anonymous spec fetches), so integration is gated behind partner onboarding and the console's iMock/iTest tooling. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Payments - United Kingdom - Cross-Border - Money Transfer - Foreign Exchange - Payouts - Payment Gateway - E-commerce - Multi-Currency - Card Issuing created: '2026-07-24' modified: '2026-07-24' specificationVersion: '0.19' apis: - aid: worldfirst:worldfirst-enterprise-solution-api name: WorldFirst Enterprise Solution API description: >- The WorldFirst Enterprise Solution (World Account) API — a RESTful, JSON, signed-request interface covering customer onboarding, account and beneficiary management, statements, foreign exchange, transfer, payout, invoicing, and virtual-card (VC) credit for globally based partners and customers.
