OneWaySMS SDK for Go

A non-official OneWaySMS SDK written for Go. Based on the latest v1.3 OneWaySMS API documentation.

Installing

Use go get to retrieve the SDK to add it to your GOPATH workspace, or project's Go module dependencies.

go get github.com/junwen-k/onewaysms-sdk-go

To update the SDK use go get -u to retrieve the latest version of the SDK.

go get -u github.com/junwen-k/onewaysms-sdk-go

Dependencies

The SDK includes a vendor folder containing the runtime dependencies of the SDK. The metadata of the SDK's dependencies can be found in the Go module file go.mod.

Usage and Getting Started

Importing the SDK

Include the following import statement to use the SDK.

package main

import (
  "github.com/junwen-k/onewaysms-sdk-go/owerr"
  "github.com/junwen-k/onewaysms-sdk-go/owsms"
)

Initializing a new client

Initialize a new client using the NewClient function. For instance:

func main() {
	svc := owsms.NewClient(
		"API_BASE_URL",
		"API_USERNAME",
		"API_PASSWORD",
		"SENDER_ID",
  )
  // ...
}

Optionally, a new client with a custom HTTP client can be initialized using the NewClientWithHTTP function. For instance:

func main() {
	svc := owsms.NewClientWithHTTP(
		"API_BASE_URL",
		"API_USERNAME",
		"API_PASSWORD",
		"SENDER_ID",
		&http.Client{Timeout: time.Second * 30},
  )
  // ...
}

Use case examples

1. Send SMS - Send SMS by calling OneWaySMS API gateway, returning mobile terminating ID(s) if request is successful.

    func main() {
      // ...
      output, _, err := svc.SendSMS(&owsms.SendSMSInput{
        Message:  "Hello, 世界",
        MobileNo: []string{"60123456789", "60129876543"},
      })
      if err != nil {
        if owErr, ok := err.(owerr.Error); ok {
          switch owErr.Code() {
          case owerr.RequestFailure:
          // Handle RequestFailure
          case owerr.InvalidCredentials:
          // Handle InvalidCredentials
          case owerr.InvalidSenderID:
          // Handle InvalidSenderID
          case owerr.InvalidMobileNo:
          // Handle InvalidMobileNo
          case owerr.InvalidLanguageType:
          // Handle InvalidLanguageType
          case owerr.InvalidMessageCharacters:
          // Handle InvalidMessageCharacters
          case owerr.InsufficientCreditBalance:
          // Handle InsufficientCreditBalance
          case owerr.UnknownError:
            // Handle UnknownError
          default:
          }
        } else {
          // Handle Generic Error
        }
      }
   
      // MTIDs - Mobile terminating IDs
      fmt.Println(output.MTIDs)
    }

2. Check MT Transaction Status - Check mobile terminating transaction status based on mobile terminating ID provided. Mobile terminating ID can be obtained by calling send SMS API.

    func main() {
      // ...
      output, _, err := svc.CheckTransactionStatus(&owsms.CheckTransactionStatusInput{
        MTID: 145712470,
      })
      if err != nil {
        if owErr, ok := err.(owerr.Error); ok {
          switch owErr.Code() {
          case owerr.MTInvalidNotFound:
          // Handle MTInvalidNotFound
          case owerr.MessageDeliveryFailure:
          // Handle MessageDeliveryFailure
          case owerr.UnknownError:
            // Handle UnknownError
          default:
          }
        } else {
          // Handle Generic Error
        }
      }
   
      switch output.Status {
      case owsms.MTTransactionStatusSuccess:
        // Handle success status
      case owsms.MTTransactionStatusTelcoDelivered:
        // Handle telco delivered status
      default:
      }
    }

3. Check Credit Balance. Check remaining credit balance for the account in the client's config.

    func main() {
      // ...
      output, _, err := svc.CheckCreditBalance()
      if err != nil {
        if owErr, ok := err.(owerr.Error); ok {
          switch owErr.Code() {
          case owerr.InvalidCredentials:
          // Handle InvalidCredentials
          case owerr.UnknownError:
            // Handle UnknownError
          default:
          }
        } else {
          // Handle Generic Error
        }
      }
   
      // CreditBalance - Remaining credit balance for this account
      fmt.Println(output.CreditBalance)
    }
