PayFast Client for Go

A client library written in Go (golang) for the PayFast payment gateway which uses no external dependencies.

Scope

This client has parity with the existing API functionality provided by PayFast.

Installation

go get -u github.com/huysamen/payfast-go

Quickstart

Create a new client default client to start accessing your PayFast account.

import payfast "github.com/huysamen/payfast-go"

pf, err := payfast.Default()

This will create a client with the default settings. It also expects the following environment variables to be set:

PAYFAST_MERCHANT_ID=[your payfast merchant id]
PAYFAST_MERCHANT_PASSPHRASE=[your payfast merchant passphrase]

You can also create a more configurable client which accepts an *http.Client as well as the merchant ID and passphrase.

pf, err := payfast.New(123, "passphrase", httpClient)

Examples and How To

Health checks

API health check

ok, err := pf.Health.Ping()

Subscriptions

Fetch subscription

sub, err := pf.Subscriptions.Fetch("subscription-token")

Update subscription

An example of how to use the nullable types:

sub, err := pf.Subscriptions.Update(
	"subscription-token",
	subscriptions.UpdateSubscriptionReq{
		Cycles:    types.Numeric{},     // default instance treated as nil and ignored
		Frequency: types.NewNumeric(types.Annual),
		//RunDate: types.Time{},        // excluded field treated as nil and ignored
		Amount: types.NewNumeric(123),
	},
)
