API Documentation
Last updated: October 7, 2026
This guide explains what the Yellow Card API is and where to find the full technical reference for integrating with it. The API is a REST-based interface that allows partners to programmatically initiate and manage transactions across supported corridors.
What the API allows businesses to do
Using the Yellow Card API, businesses 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
The complete technical reference is maintained at the Yellow Card Developer Docs site and includes endpoint descriptions, request/response schemas, authentication guides, error codes, and integration examples.
Documentation is regularly updated as new features and corridors are introduced.
