## Introduction

With the launch of the v2 version of the X API, we have adopted a new data response format and method of requesting different objects and fields, which we are simply calling the X API v2 format. 

In the general differences section, you can learn about some changes that are relevant to standard, and enterprise users. However, we also put together a specific guide for the [standard v1.1 Native format](https://developer.x.com/en/docs/x-api/v1/data-dictionary/overview), the enterprise [Native Enriched format](/x-api/enterprise-gnip-2.0/fundamentals/data-dictionary#native-enriched-tweet-object), and the enterprise [Activity Streams format](/x-api/enterprise-gnip-2.0/fundamentals/data-dictionary#activity-object) which helps to map fields and explains which fields and expansions you must use to request the new v2 fields.

### General differences

#### Requesting objects and fields

One of the biggest changes between the pre-v2 endpoints and v2 is that the newer version only returns a few fields by default, whereas standard, premi
