Authentication
Twitter APIs handle enormous amounts of data. The way we ensure this data is secured for developers and users alike is through authentication. There are a few methods for authentication, each listed below.
Most developers will not need to work with the details of authentication as Twitter client libraries already implement the protocol. Supported libraries >
Authentication methods
OAuth 1.0a
OAuth 1.0a allows an authorized Twitter developer app to access private account information or perform a Twitter action on behalf of a Twitter account.
OAuth 2.0 Bearer Token
OAuth 2.0 Bearer Token allows a Twitter developer app to access information publicly available on Twitter.
Basic authentication
Many of Twitter’s enterprise APIs require the use of HTTP Basic Authentication.
When to use
The most common methods used by the Twitter Developer Platform are OAuth 1.0a and OAuth 2.0 Bearer Token. The best place to check the authentication method required for an endpoint is the API reference page.
Some differences between OAuth 1.0a and OAuth 2.0 Bearer Token methods are:
| Use case | OAuth 1.0a | OAuth 2.0 Bearer Token |
| Search Tweets | ✔ | ✔ |
| Pull user timelines | ✔ | ✔ |
| Get trends data | ✔ | ✔ |
| Post, like, or Retweet a Tweet | ✔ | |
| Retrieve a users' email address | ✔ | |
| Read or write advertiser data | ✔ | |
Required keys and tokens |
Consumer API Keys + Access Token & Access Token Secret |
Bearer Token |
| Rate Limits | Distinct per User and sometimes Twitter developer app | Distinct per Twitter developer App |
Please note
Your app's Consumer API Keys and Bearer Token, as well as your personal Access Token and Access Token Secret can be obtained from the Twitter developer apps section found in the developer portal. To generate access tokens for a different user, you will need to use the 3-legged OAuth process.
