Sleet

Payment abstraction library - interact with different Payment Service Providers (PsP) with one unified interface.

Installation

go get github.com/BoltApp/sleet

Methodology

Wherever possible, we try to use native Golang implementations of the PsP's API. We also assume that the caller can pass along raw credit card information (i.e. are PCI compliant)

Supported Gateway API Calls

Authorize
Capture
Void
Refund

Webhooks Support

We support abstracting PsP Webhook notifications into a common interface.

Code Example for Auth + Capture

import (
  "github.com/BoltApp/sleet"
  "github.com/BoltApp/sleet/gateways/authorize_net"
)
// Generate a client using your own credentials
client := authorize_net.NewClient("AUTH_NET_LOGIN_ID", "AUTH_NET_TXN_KEY")

amount := sleet.Amount{
  Amount: 100,
  Currency: "USD",
}
card := sleet.CreditCard{
  FirstName: "Bolt",
  LastName: "Checkout",
  Number: "4111111111111111",
  ExpMonth: 8,
  EpxYear: 2010,
  CVV: "000",
}
streetAddress := "22 Linda St."
locality := "Hoboken"
regionCode := "NJ"
postalCode := "07030"
countryCode := "US"
address := sleet.BillingAddress{
  StreetAddress1: &streetAddress,
  Locality:       &locality,
  RegionCode:     &regionCode,
  PostalCode:     &postalCode,
  CountryCode:    &countryCode,
}
// To get specific response headers, add them to the request options.
// They will be attached to the AuthorizationResponse
options := make(map[string]interface{})
options["ResponseHeader"] = []string{"x-test-header"}
authorizeRequest := sleet.AuthorizationRequest{
  Amount: &amount,
  CreditCard: &card,
  BillingAddress: &address,
  Options: options,
}
authorizeResponse, _ := client.Authorize(&authorizeRequest)

captureRequest := sleet.CaptureRequest{
  Amount:               &amount,
  TransactionReference: authorizeResponse.TransactionReference,
}
client.Capture(&captureRequest)
