Deprecation notice: New Version Available

This version of the SDK has been deprecated and replaced with the newly reconstructed SDK.

For the latest API features and improved integration, please visit our updated repository at https://github.com/AfterShip/tracking-sdk-go and follow the provided instructions.

aftership-sdk-go

Introduction

AfterShip provides an API to Track & Notify of shipments from hundreds of couriers worldwide. aftership-sdk-go is a SDK to develop Apps using AfterShip API 2023-10 in golang. All endpoints including couriers, tracking, last checkpoint and notification are supported.

You will need to create an account at AfterShip and obtain an API key first to access AfterShip APIs using aftership-go SDK.

Installation

aftership-sdk-go requires a Go version with Modules support and uses import versioning. So please make sure to initialize a Go module before installing aftership-sdk-go:

go mod init github.com/my/repo
go get github.com/aftership/aftership-sdk-go/v3

Import:

import "github.com/aftership/aftership-sdk-go/v3"

Quick Start

package main

import (
        "context"
        "fmt"

        "github.com/aftership/aftership-sdk-go/v3"
)

func main() {

        client, err := aftership.NewClient(aftership.Config{
                APIKey: "YOUR_API_KEY",
        })

        if err != nil {
                fmt.Println(err)
                return
        }

        // Get couriers
        result, err := client.GetCouriers(context.Background())
        if err != nil {
                fmt.Println(err)
                return
        }

        fmt.Println(result)
}

Test

make test

NewClient(config)

Create AfterShip SDK instance with config

config - object of request config
- APIKey - Required, AfterShip API key
- AuthenticationType - APIKey / AES
- APISecret - if AuthenticationType is AES, use aes api secret
- Endpoint - string, AfterShip endpoint, default 'https://api.aftership.com/tracking/2023-10'
- UserAagentPrefix - string, prefix of User-Agent in headers, default "aftership-sdk-go"

Example:

AuthenticationType APIKey

client, err := aftership.NewClient(aftership.Config{
    APIKey: "YOUR_API_KEY",
    UserAagentPrefix: "aftership-sdk-go",
})

AuthenticationType AES signature

client, err := aftership.NewClient(aftership.Config{
    APIKey:             "YOUR_API_KEY",
    AuthenticationType: aftership.AES, 
    APISecret:          "YOUR_API_SECRET",
})

Rate Limiter

To understand AfterShip rate limit policy, please see Limit section in https://www.aftership.com/docs/tracking/quickstart/rate-limit

You can get the recent rate limit by client.GetRateLimit(). Initially all value are 0.

import (
    "context"
    "fmt"

    "github.com/aftership/aftership-sdk-go/v3"
)

func main() {
    client, err := aftership.NewClient(aftership.Config{
        APIKey: "YOUR_API_KEY",
    })

    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(client.GetRateLimit())

    // terminal output
    /*
    {
        "reset": 0,
        "limit": 0,
        "remaining": 0,
    }
    */

    // Get couriers
    result, err := client.GetCouriers(context.Background())
    if err != nil {
        fmt.Println(err)
    } else {
        fmt.Println(result)
    }

    // Rate Limit
    fmt.Println(client.GetRateLimit())

    // terminal output
    /*
    {
        "reset": 1588249242,
        "limit": 10,
        "remaining": 9,
    }
    */
}

In case you exceeded the rate limit, you will receive the 429 Too Many Requests error with the following error message:

{
  "code": 429,
  "type": "TooManyRequests",
  "message": "You have exceeded the API call rate limit. Default limit is 10 requests per second.",
  "path": "/couriers",
  "rate_limit": {
    "rest": 1458463600,
    "limit": 10,
    "remaining": 0
  }
}

Error Handling

There are 3 kinds of error

SDK Error
Request Error
API Error

SDK Error

Throw by the new SDK client

client, err := aftership.NewClient(aftership.Config{
    APIKey: "",
})

if err != nil {
    fmt.Println(err)
    return
}

/*
invalid credentials: API Key must not be empty
*/

Throw by the parameter validation in function

client, err := aftership.NewClient(aftership.Config{
    APIKey: "YOUR_API_KEY",
})

// Get notification
param := aftership.SlugTrackingNumber{
    Slug: "dhl",
}

result, err := client.GetNotification(context.Background(), param)
if err != nil {
    fmt.Println(err)
    return
}

fmt.Println(result)

/*
slug or tracking number is empty, both of them must be provided
*/

Request Error

client, err := aftership.NewClient(aftership.Config{
    APIKey: "YOUR_API_KEY",
})

// Get couriers
result, err := client.GetCouriers(context.Background())
if err != nil {
    fmt.Println(err)
    return
}

fmt.Println(result)
/*
HTTP request failed: Get https://api.aftership.com/v4/couriers: dial tcp: lookup api.aftership.com: no such host
*/

API Error

Error return by the AfterShip API https://www.aftership.com/docs/tracking/quickstart/request-errors

API Error struct of this SDK contain fields:

Code - error code for API Error
Type - type of the error
Message - detail message of the error
Path - URI path when making request
RateLimit - Optional - When the API gets 429 Too Many Requests error, the error struct will return the RateLimit information as well.

client, err := aftership.NewClient(aftership.Config{
    APIKey: "INVALID_API_KEY",
})

// Get couriers
result, err := client.GetCouriers(context.Background())
if err != nil {
    fmt.Println(err)
    return
}

fmt.Println(result)
/*
{
  "code": 401,
  "type": "Unauthorized",
  "message": "Invalid API key.",
  "path": "/couriers"
}
*/

Examples
