Google Ad Api quick-start(2)
===

[TOC]

## 筆記目的

完成串接Google Ad APi 的串接部分，具體來說可以執行官網上的
GetCampaigns.java範例

具體請參考:

* [Google Ad Api quickstart](https://developers.google.com/google-ads/api/docs/first-call/get-campaigns)

## 先備條件

請務必先拿到以下六個東西

1. Default_ClientId
2. Default_ClientSecret
3. Default_RefreshToken
4. Default_DeveloperToken
5. loginCustomerId (MCC)
6. requestCustomerId(廣告客戶)

## 程式碼部分

### 專案架構


總共會有兩個java檔案，分別是GetCampaings_Test以及Connect，
前者含有main方法，後者則有封裝後的參數

### Connect

package com.example.demo.util;

public class Connect {
	
	public static final String Default_ClientId = "XXX";
	public static final String Default_ClientSecret = "XXX";
	public static final String Default_RefreshToken = "XXX";
	public static final String Default_DeveloperToken = "XXX";
	public static final Long loginCustomerId = XXXL;// mcc
	public static final Long requestCustomerId = XXXL;  //廣告客戶

}

### GetCampaings_Test
