This page contains information on several tools and key concepts that you should be aware of as you integrate the blocks endpoints into your system. We’ve broken the page into a couple of different sections:
- Helpful tools
- Key Concepts
- Developer portal, Projects, and Apps
- Rate limits
- Fields and expansions
Before we dive into some key concepts that will help you integrate this endpoint, we recommend that you become familiar with:
Postman is a great tool that you can use to test out an endpoint. Each Postman request includes every path and body parameter to help you quickly understand what is available to you. To learn more about our Postman collections, please visit our "Using Postman" page.
Interested in getting set up with this endpoint with some code in your preferred coding language? We’ve got a handful of different code samples available that you can use as a starting point on our Github page.
Take advantage of one of our communities’ third-party libraries to help you get started. You can find a library that works with the v2 endpoints by looking for the proper version tag.
All Twitter API v2 endpoints require you to authenticate your requests with a set of credentials, also known as keys and tokens. You can use either OAuth 1.0a User Context or OAuth 2.0 Authorization Code with PKCE to authenticate your requests to these endpoints.
OAuth 1.0a User Context requires you to utilize your API Keys, user Access Tokens, and a handful of other parameters to create an authorization header, which you will then pass with your request. The Access Tokens must be associated with the user that you are making the request on behalf of. If you would like to generate a set of Access Tokens for another user, they must authorize your App using the 3-legged OAuth flow.
Please note that OAuth 1.0a can be difficult to use. If you are not familiar with this authentication method, we recommend that you use a library, use a tool like Postman, or use OAuth 2.0 to authenticate your requests.
OAuth 2.0 Authorization Code with PKCE allows for greater control over an application’s scope, and authorization flows across multiple devices. OAuth 2.0 allows you to pick specific fine-grained scopes which give you specific permissions on behalf of a user.
To enable OAuth 2.0 in your App, you must enable it in your’s App’s authentication settings found in the App settings section of the developer portal.
To retrieve a set of authentication credentials that will work with the Twitter API v2 endpoints, you must sign up for a developer account, set up a Project within that account, and created a developer App within that Project. You can then find your keys and tokens within your developer App.
Every day, many thousands of developers make requests to the Twitter API. To help manage the sheer volume of these requests, rate limits are placed on each endpoint that limits the number of requests that you can make on behalf of your app or on behalf of an authenticated user.
These endpoints are rate limited at the user level, meaning that the authenticated user that you are making the request on behalf of can only call the endpoint a certain number of times across any developer App. There is a user rate limit of 50 requests per 15 minutes per endpoint with both POST and DELETE methods. However, with the GET method, the rate limit is only 15 requests per 15 minutes.
The Twitter API v2 GET endpoints allow users to select exactly which data they want to return from the API using a set of tools called fields and expansions. The expansions parameter allows you to expand objects referenced in the payload. For example, this endpoint allows you to pull the following expansions:
The fields parameter allows you to select exactly which fields within the different data objects you would like to receive. These endpoints delivers Tweet objects primarily. By default, the Tweet object returns the id and text fields. To receive additional fields such as tweet.created_at or tweet.entities, you will have to specifically request those using a fields parameter. Some important fields that you may want to consider using in your integration are our poll data, metrics, Tweet annotations, and conversation ID fields.
Blocks lookup can return a lot of data. To ensure we don’t return to many results at any given time, we use pagination. Learn more about how to paginate through results.
