Initialize a Paystack transaction. Returns payment link/authorization.
AI agents use paystack_initialize to commit financial operations through Africa Payments MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool initiates a financial transaction via Paystack, a payment processing platform. Initializing a transaction creates a financial obligation or payment flow that can lead to real money movement. Even though it returns a payment link (not completing the payment directly), it is the first step in committing a financial transaction, placing it firmly in the Financial category.
