Interswitch
Interswitch is Nigeria's foundational digital payments and transaction-switching company, founded in 2002 and regulated by the Central Bank of Nigeria. It owns the Verve card scheme (Africa's first domestic EMV chip-and-PIN brand), the Quickteller consumer and business payments platform, the Webpay / Web Checkout gateway, the Paycode cardless service, and the underlying transaction switch that connects Nigerian banks, fintechs, billers, and merchants. The Interswitch developer platform exposes REST APIs for accepting payments, sending transfers, paying bills, recharging airtime, generating cardless tokens, issuing Verve cards (Card 360), originating loans, accessing customer insights, and searching transactions — all under OAuth 2.0 client-credentials authentication via the Passport token service and HMAC-SHA512-signed webhooks. The company is expanding from Nigeria into Ghana, Kenya, Uganda, and other African markets.
Interswitch publishes 32 APIs on the APIs.io network, including Transfers API, Refunds API, Airtime API, and 29 more. Tagged areas include Payments, Payment Infrastructure, Card Network, Verve, and Quickteller.
The Interswitch catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
