Integration guide

This page contains information on several tools and key concepts that you should be aware of as you integrate the mutes endpoints into your system. We’ve broken the page into a couple of different sections:

• Helpful tools
• Key Concepts
• Authentication
• Developer portal, Projects, and Apps
• Rate limits
• Fields and expansions

Helpful tools

Before we dive into some key concepts that will help you integrate this endpoint, we recommend that you become familiar with:

Postman

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. 

Code samples

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.

Third-party libraries

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.

Key concepts

Authentication

All X API v2 endpoints require you to authenticate your requests with a set of credentials, also known as keys and tokens. You can use OAuth 1.0a User Context to authenticate your requests to this endpoint. 

OAuth 1.0a User Context, which means that you must use a set of API Keys and user Access Tokens to make a successful 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.

Developer portal, Projects, and developer Apps

To retrieve a set of authentication credentials that will work with the X 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.
 

Rate limits

Every day, many thousands of developers make requests to the X API. To help manage the sheer volume of these requests, rate limits are placed on each endpoint that limits the number of requests 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. 

The chart below shows the rate limits for each endpoint.

Fields and expansions

The X API v2 GET endpoint allows 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, looking up pinned Lists allows you to pull the following expansions:

• owner_id

The fields parameter allows you to select exactly which fields within the different data objects you would like to receive. This endpoint delivers user objects primarily. By default, the List object returns the id, and name fields. To receive additional fields such as list.created_at or list.description, you will have to specifically request those using a fields parameter. 

We’ve added a guide on using fields and expansions together to our X API v2 data dictionary.
