Golang Coinpayments wrapper library

NOTE: This project started as a fork of jeffwalsh/go-coinpayments project, but rapidly evolved to its own. While we thank and credit original creator for the job so far, we are going separate ways for the time being.

This is the only coinpayments golang wrapper library officially supported and maintained by Tryvium Travels LTD

Coinpayments Golang wrapper. To use, instantiate a *coinpayments.Client by calling the coinpayments.NewClient function. You will need to pass in a valid instance of the *coinpayments.Config struct, consisting of your private and public keys, as well as an instance of your desired http client.

This looks like:

import (
  "github.com/tryvium-travels/go-coinpayments"
)

func main() {
  clientConfig := &coinpayments.Config{
    PublicKey: "your-public-key",
    PrivateKey: "your-private-key",
  }
  httpClient := &http.Client{
    Timeout: 10 * time.Second,
  }

  client, err := coinpayments.NewClient(clientConfig, httpClient)
  if err != nil {
    // handle error...
  }

  // ...
}

Once instantiated, you can use the client to make API calls. Each call has their own Request struct, and returns it's own Response struct.

An example of the create_transaction command being called:

import (
  "github.com/tryvium-travels/go-coinpayments"
)

func main() {
  clientConfig := ...
  httpClient := ...
  client, err := coinpayments.NewClient(clientConfig, httpClient)
  if err != nil {
    // handle error...
  }

  resp, err := client.CallCreateTransaction(
    &coinpayments.TransactionRequest{
      Amount: "1", // the amount is the value of the fiat currency you wish to receive
      Currency1: "USD", // currency that amount is specified in (USD, CAD, JPY, etc)
      Currency2: "BTC", // currency in crypto that you wish to receive (BTC, ETC, LTC, etc)
      BuyerEmail: "test@email.com", // our client requires the buyer email address
    }
  )
  if err != nil {
    // handle error...
  }
}

Usage

You can use Call to call any command directly. You just need to build out your own data with an url.Values, and create an instance of the responsestruct expected by your command, then pass in the relevant command from the coinpayments package, ie, coinpayments.CmdCreateTransaction.

Here is an example of getting the deposit address:

import (
  "net/url"

  "github.com/tryvium-travels/go-coinpayments"
)

func main() {
  clientConfig := ...
  httpClient := ...
  client, err := coinpayments.NewClient(clientConfig, httpClient)
  if err != nil {
    // handle error...
  }

  var data url.Values
  data.Add("currency", "USD")

  var resp coinpayments.DepositAddressResponse
  err := c.Call(coinpayments.CmdGetDepositAddress, data, &resp)
  if err != nil {
    // handle error...
  }
}

Testing the library

You need to export two environment variables for the tests to run - your public key, and private key.

export COINPAYMENTS_PUBLIC_KEY="your-public-key-here"
export COINPAYMENTS_PRIVATE_KEY="your-private-key-here"

go test ./...

If you want to run the PBN Tag tests and have purchased a PBN Tag, you can also export it, and those tests will run. Otherwise, they will be ignored.

export COINPAYMENTS_PBN_TAG="your-pbn-tag-here"
