// A resource representing a Payer's funding instrument.

// and provided by the facilitator. This is required when
// creating or using a tokenized funding instrument)
// and the `CreditCardDetails`
$fi = new FundingInstrument();

// Pass in a `ApiContext` object to authenticate
// the call and to send a unique request id
// (that ensures idempotency). The SDK generates
// a request id if you do not pass one explicitly.

// Create a payment by posting to the APIService
// using a valid apiContext
// The return object contains the status;
