原文：
As of July 2018, you must apply for a Twitter developer account and be approved before you may create new apps. Once approved, you will be able to create new apps from developer.twitter.com.
For the near future, you can continue to manage existing apps here on apps.twitter.com. However, we will soon retire this site and consolidate all developer tools, API access, and app management within the developer portal at developer.twitter.com. You will be able to access and manage existing apps through that portal when we retire this site.
Get started with Twitter APIs and tools：https://developer.twitter.com/en/apply-for-access.html
All new developers must apply for a developer account to access Twitter APIs. Once approved, you can begin to use our standard APIs and our new premium APIs.
More about restricted uses of the Twitter APIs：https://developer.twitter.com/en/developer-terms/more-on-restricted-use-cases
费用问题：
1. Create a Twitter app.
- Create a Twitter app with an approved developer account from the developer portal. If you are creating the app on behalf of your company, it is recommended you create the app with a corporate Twitter account. To apply for a developer account, click here.
- Enable “Read, Write and Access direct messages” on the permissions tab of your app page.
- On the "Keys and Access Tokens" tab, take note of your app's Consumer Key (API Key) and Consumer Token (API Secret).
- On the same tab, generate your app's Access Token and Access Token Secret. You will need these Access Tokens to register your webhook URL, which is where Twitter will send account events.
- If you are unfamiliar with Twitter Sign-in and how user contexts work with the Twitter API review Obtaining Access Tokens. As you add accounts for which to receive events, you will subscribe them using that account's access tokens.
- Take note of your app's numeric ID, as seen in the "Apps" page of the developer portal. When you apply for Account Activity API access, you'll need this app ID.
2. Get Account Activity API access
After creating a Twitter app, the next step is applying for Account Activity API access.
Premium
To access the Sandbox or Paid Premium Account Activity API tiers, you need to set up a developer account. If you have not applied for a developer account yet, please do so at the following link:
Once you have a developer account, then you are ready to set up
your access to the Premium Account Activity API. You will need a
registered
- Login and navigate to the "Dev Environments" page.
- Click 'Set up dev environment,' name your environment, and specify a Twitter app ID for the environment. The environment name you chose will replace the :env_name
token in our example premium endpoint URLs. For example, if you use the
'prod' environment name, your URL pattern would be
https://api.twitter.com/1.1/account_activity/all/prod/webhooks.
Enterprise
Those needing enterprise level access to more than 250 account subscriptions and 3+ webhooks will need to submit an application at the following link:
- Create a web app with a URL to use as your webhook to receive events. This is the endpoint deployed on your server to listen for incoming Twitter webhook events.
- The URI path is completely up to you. This example would be valid: https://mydomain.com/service/listen
- If you are listening for webhooks from a variety of sources, a common pattern is: https://mydomain.com/webhook/twitter
- Note that the specified URL can not include a port specification (https://mydomain.com:5000/NoWorkie).
- The URI path is completely up to you. This example would be valid: https://mydomain.com/service/listen
- As described in our Securing Webhooks guide, a first step is writing code that receives a Twitter Challenge Response Check (CRC) GET request and responds with a properly formatted JSON response.
- Register your webhook URL. You will make a POST request to a /webhooks.json?url= endpoint.
When you make this request Twitter will issue a CRC request to your web
app. When a webhook is successfully registered, the response will
include a webhook id. This webhook id is needed later when making some requests to the Account Activity API.
- Twitter will send account webhook events to the URL you registered. Make sure your web app supports POST requests for incoming events. These events will be encoded in JSON. See HERE for example webhook JSON payloads.
- Once your web app is ready, the next step is adding accounts to
receive activities for. When adding (or deleting) accounts you will make
POST requests referencing the account id. See our guide on adding subscriptions for more information.
4. Validate setup
- To validate your app and webhook are configured correctly, favorite a
Tweet posted by one of the Twitter accounts your app is subscribed to.
You should receive a
favorite_eventsvia a POST request to your webhook URL for each Favorite your subscribers receive.

Advertise on the Twitter network
Twitter’s Ads API endpoints provide developers a programmatic way to create and manage Twitter Ads campaigns. In addition, these endpoints provide a means to access features like Audiences, Creatives, Targeting, etc. Our tutorials page contains all the necessary information around the Ads entity hierarchy as well as a basic getting started guide.
Apply for Ads API access
In order to be able to use any of the Ads API endpoints, first create a Twitter app and apply for access here. Feel free to play around in our sandbox environment as well.
Check out our SDKs
The Python and Ruby SDKs provide a frictionless means to integrate with the Ads API directly in your application.
If you’re an expert on the Ads API feel free to help out others as well! Questions? See our developer forums.

获取TwitterAPI keys
• 注册一个Twitter账号
• 到https://apps.twitter.com/登入twitter账号
• 点击“Create New App”，新建你自己的应用
• 填写应用信息表单, 然后点击“Create your Twitter application”生成你的twitter应用
• 在“keys and Access Tokens”界面, 点击“API keys”, 然后记录你的“API key” 和"API secret".
• 在“keys and Access Tokens”界面点击“Create my access token”, 记录你的"Access token" and "Access token secret".
这里我就不啰嗦一步一步截图了，按照上面一步一步做就行。但是只里面有一个坑，需要注意的：twitter在创建应用时，你的twitter账号一定要绑定你的手机，但是国内的手机运营商收不到验证码。这里好像可以用手机版twitter去绑定手机号（实测联通可以收到验证码，电信好像不可以，移动没试过）
使用TwitterAPI
这里我使用的twitter4J来调用twitter接口。
Twitter4j：http://twitter4j.org/en/index.html
在这里你下载twitter4j的zip包然后解压，将lib下面的这些jar包导入你的项目中。
twitter4j-core-source.jar包是自己打包的源码包，用来查看函数源码。
注：twitter4j的文档写的很不全，参考意义不是很大，你可以结合下载zip包中的examples文件夹中的例子还可以看twitter官网的Twitter REST APIs：https://dev.twitter.com/rest/public
twitter4j是的使用需要翻墙代理，还有当你设置好以后，有可能会碰到链接拒绝（看你用的什么代理），因为eclipse默认走的是ipv6协议，具体解决方法可以参考我这篇文章：

If you have created a Twitter app via the apps.twitter.com platform before July 24th, then you will be able to manage that Twitter app via apps.twitter.com for the foreseeable future. If you have applied for a new developer account, you will also be able to edit manage that Twitter app via the developer portal as well. Since July 24th, you are required to have an approved developer account to create new apps.
If you are using one of the POST endpoints (Tweet, Retweet, Favorite, DM, Follow), you are currently rate limited based on the user level. On October 22nd (announcement about the delay), there will be new App level rate limits applied to those endpoints. These POST rate limits will be applied to all Twitter apps, regardless of when they were created.
Initial Setup
As a developer, there are several steps that you will need to take in order to begin using the Direct Messages services.
Step 1 - Create a Twitter app.
- Create an app on the "Apps" page of your approved developer account. If you are creating the app on behalf of your company, it is recommended you create the app with a corporate Twitter account.
- Enable “Read, Write and Access direct messages” on the permissions tab of your app page.
- On the "Keys and Tokens" tab, take note of your app's Consumer Key (API Key) and Consumer Token (API Secret).
- On the same tab, generate your app's Access Token and Access Token Secret. You will need these Access Tokens to register your webhook URL, which is where Twitter will send account events.
- If you are unfamiliar with Twitter Sign-in and how user contexts work with the Twitter API review Obtaining Access Tokens. As you add accounts for which to receive events, you will subscribe them using that account's access tokens.
- Take note of your app's numeric ID, as seen in the "Apps" page of the developer portal. When you apply for Account Activity API access, you'll need this app ID.
Step 2 - Get access to Account Activity API
After creating a Twitter app, the next step is applying for Account Activity API access.
Premium
To access the Sandbox or Paid Premium Account Activity API tiers, you need to set up a developer account. If you have not applied for a developer account yet, please do so at the following link:
Once you have a developer account, then you are ready to set up your access to the Premium Account Activity API. You will need a Twitter app to attach to your Account Activity API dev environment.
- Login and navigate to the Dev Environments page.
- Click 'Set up dev environment,' name your environment, and specify a Twitter app ID for the environment. The environment name you chose will replace the :env_name
token in our example premium endpoint URLs. For example, if you use the
'prod' environment name, your URL pattern would be
https://api.twitter.com/1.1/account_activity/all/prod/webhooks.
Step 3 - Develop webhook consumer app
If you would like to use a script with a visual dashboard to get set up with your account activities, you should check out the Twitter Dev-supported Account Activity Dashboard.
- Once you have received Account Activity API access, you need to develop, deploy and host a web app that will receive Twitter webhook events.
- Create a web app with a URL to use as your webhook to receive
events. This is the endpoint deployed on your server to listen for
incoming Twitter webhook events.
- The URI path is completely up to you. This example would be valid: https://mydomain.com/service/listen
- If you are listening for webhooks from a variety of sources, a common pattern is: https://mydomain.com/webhook/twitter
- Note that the specified URL can not include a port specification (https://mydomain.com:5000/NoWorkie).
- As described in our Securing Webhooks guide, a first step is writing code that receives a Twitter Challenge Response Check (CRC) GET request and responds with a properly formatted JSON response.
- Register your webhook URL. You will make a POST request to a /webhooks.json?url= endpoint. When you make this request Twitter will issue a CRC request to your web app. When a webhook is successfully registered, the response will include a webhook id. This webhook id is needed later when making some requests to the Account Activity API.
- Twitter will send account webhook events to the URL you registered. Make sure your web app supports POST requests for incoming events. These events will be encoded in JSON. See HERE for example webhook JSON payloads.
- Once your web app is ready, the next step is adding accounts to receive activities for. When adding (or deleting) accounts you will make POST requests referencing the account id. See our guide on adding subscriptions for more information.
- To validate your app and webhook are configured correctly, favorite a Tweet posted by one of the Twitter accounts your app is subscribed to. You should receive a Favorite event via a POST request to your webhook URL for each Favorite your subscribers receive.
Step 4 - Obtain User Permission
In order to perform write actions (create Tweets or messages) on behalf of another account or to read private information from that account, you will need to obtain access tokens. Access tokens provide the user context when using the Twitter API.
Basic Definitions
- User - A Twitter @user. All write actions on the Twitter API require the context of a user. Chatbots exist on Twitter accounts and are not their own entity. The account the chatbot exists on is a user. Customers interacting with the chatbot are also users. All messages sent on Twitter are between two user entities.
- App - A Twitter app is created in your approved developer account. An app is always owned by a single user. The app provides the base context for using the Twitter API.
How are tokens generated? Two scenarios:
- User owns the app / Single User - If the user is the owner of the app, they can generate access tokens on the “Keys and Tokens” tab in an app's "Details" section within the from the "Apps" page in the developer portal. Click the “Create” button on the bottom of the page.
- User does not own the app / Multiple Users - If your app is going to consume Account Activity events on behalf of multiple users, each user must authenticate with your app to grant permission. To achieve this you must have a web app that implements Twitter Sign-in.
At this point in the process, you should have all of the necessary information to set up an application in the developer portal, perform the initial Challenge Response Check to secure your endpoint, and obtain access tokens in order to publish content on both your own application and on behalf of others who have given explicit permission. Now let's take a look at the different endpoints we will be using in our app.
Step 5 - Understanding how the endpoints fit together
To make experiences conversational we provide Direct Message data in real time via webhooks which includes metadata about the features in that experience. Additionally, we have REST endpoints to create messages, get welcome messages and custom profile data, and manage these features. Understanding the basic flow below will help you set up your own app based on the sample app you cloned in step 3.
Direct Messages
- Data about Direct Messages (sent and received) is provided to
developers in real-time via their Account Activity API webhook setup
- Register a webhook URL for the APP:
- API call to POST account_activity/all/:env_name/webhooks
- Developers can only register 1 URL per environment
- Developer will ask the user to authorize the app via Twitter Sign-in to generate valid access tokens.
- Add a new subscription (enable the app to receive Direct Messages on behalf of the user via the registered webhook)
- API call to POST account_activity/all/:env_name/subscriptions
- User needs to have a valid access token with the app (step 4)
- Validate your webhooks URL using the PUT account_activity/all/:env_name/webhooks endpoint
- Retrieve your webhook configuration using the GET account_activity/all/:env_name/webhooks endpoint
- Register a webhook URL for the APP:
- Get all Direct Messages sent and received in the last 30 days using the GET direct_messages/events/list endpoint
- Get a single Direct Message based on the ID using the GET direct_messages/events/show endpoint, there’s no time restriction on this endpoint
- Send a message using POST direct_messages/events/new (message_create)
- This endpoint is referenced in the send-direct-message script here
Welcome Messages
- Create a new welcome message using POST direct_messages/welcome_messages/new
- This endpoint is referenced in the create-welcome-message script here
- Create a new rule for welcome messages using POST direct_messages/welcome_messages/rules/new
- This endpoint is referenced in this script here
Subscription Endpoints
- Delete a subscriptions using DELETE account_activity/webhooks/:webhook_id/subscriptions
- This endpoint is referenced in this script
- Get your current webhook configuration using GET account_activity/webhooks
- This endpoint is referenced in this script
