API Documentation

The YellowCard API enables businesses to integrate stablecoin-powered payment, send

and receive transactions directly into their platforms. This article provides an overview of

what the API covers and where to find the full technical documentation.

About the API

The YellowCard API is a REST-based interface that allows partners to programmatically initiate and manage transactions across supported corridors. It is designed for businesses that need to send or receive local currency payments, settle in stablecoins, or build payment flows into their existing products.

With the API, partners can:

• Send payments to bank accounts and mobile money wallets

• Receive payments from end-users in local currency

• Access real-time FX rates across supported corridors

• Retrieve transaction status and history

• Manage KYC submissions for end-users

• Handle direct settlement transactions involving cryptocurrency

API Documentation

The full API reference, including endpoint descriptions, request and response schemas, authentication guides, error codes, and integration examples, is available in the YellowCard developer documentation.

The documentation is kept up to date as new features and corridors are added. Partners are encouraged to check it regularly for any changes relevant to their integration.
