Similarities

OAuth 2.0 Bearer Token

Both the premium version of the Search API and the v2 version of full-archive search require authentication with OAuth 2.0 Bearer Token. Therefore, if you were previously using the premium version of the endpoint you can continue using the same authentication method if you migrate to the Twitter API v2 version.

Please note that the v2 recent search endpoint allows for you to authenticate with OAuth 1.0a User Context or OAuth 2.0 Bearer Token, whereas full-archive search only allows OAuth 2.0 Bearer Token.
 

Pagination

While v2 has additional pagination features (new pagination parameters that allow you to navigate using Tweet IDs with since_id and until_id), both premium and v2 allow you to paginate using time (fromDate and toDate with premium, and start_time and end_time for v2).

If you are using the premium version, you will use the next parameter to paginate, the next token field will be called next, and it will be located at the root in the response.

If you are using v2, you can use either the next_token or pagination_token parameter to paginate, and your next token will be located at meta.next_token in the response.
 

Timezone

As noted in the pagination section, you can navigate different pages of data using time for both premium and v2. In both cases, you will be using UTC as the timezone when using these parameters.

Differences

Endpoint URLs

• Premium endpoints:
  • 30 day - https://api.twitter.com/1.1/tweets/search/30day/:label.json
  • Full-archive - https://api.twitter.com/1.1/tweets/search/fullarchive/:label.json
• Twitter API v2 endpoints
  • Recent (7 day) - https://api.twitter.com/2/tweets/search/recent
  • Full-archive - https://api.twitter.com/2/tweets/search/all

App and Project requirement

The Twitter API v2 endpoints require that you use credentials from a developer App that is associated with a Project when authenticating your requests. All Twitter API v1.1 endpoints can use credentials from standalone Apps or Apps associated with a Project.
 

Available time periods

Both the premium API and Twitter API v2 offer endpoints that allow you to search Tweet data from the full-archive of Tweets.

However, the Twitter API v2 does not offer a 30 day time period endpoint like the Premium API does. Instead it offers the aforementioned full-archive, or a 7 day time period, which align with the v2 Tweet counts endpoints.
 

Response data format

We have put together a data format migration guide which can help you map premium fields to the newer v2 fields. This guide will also provide you the specific expansion and field parameter that you will need to pass with your v2 request to return specific fields.

One of the biggest differences between the premium response format, also known as Native Enriched, and Twitter API v2’s format is how you select which fields return in your payload.

For the premium Search API, you receive many of the response fields by default, and then have the option to use parameters to identify which fields or sets of fields should return in the payload.

The Twitter API v2 version only delivers the Tweet id and text fields by default. To request any additional fields or objects, you will need to use the fields and expansions parameters. Any Tweet fields that you request from these endpoints will return in the primary Tweet object. Any expanded user, media, poll, or place objects and fields will return in an includes object within your response. You can then match any expanded objects back to the Tweet object by matching the IDs located in both the Tweet and the expanded object.

We encourage you to read more about these new parameters in their respective guides, or by reading our guide on how to use fields and expansions.

In addition to the changes in how you request certain fields, Twitter API v2 is also introducing new JSON designs for the objects returned by the APIs, including Tweet and user objects.

• At the JSON root level, the standard endpoints return Tweet objects in a statuses array, while Twitter API v2 returns a data array.
• Instead of referring to Retweeted and Quoted "statuses", Twitter API v2 JSON refers to Retweeted and Quoted Tweets. Many legacy and deprecated fields, such as contributors and user.translator_type are being removed.
• Instead of using both favorites (in Tweet object) and favourites (in user object), Twitter API v2 uses the term like.
• Twitter is adopting the convention that JSON values with no value (for example, null) are not written to the payload. Tweet and user attributes are only included if they have non-null values.
   

We also introduced a new set of fields to the Tweet object including the following:

• A conversration_id field
• Two new annotations fields, including context and entities
• Several new metrics fields
• A new reply_setting field, which shows you who can reply to a given Tweet
   

And one last note. The premium response includes a requestParameters object at the root level, which contains the parameters that you included in your request. The v2 version instead contains a meta object that lives at the root level which includes the newest_id, oldest_id, result_count, and next_token if there is an additional page of results.
 

HTTP methods

The premium version of the API allows you to pass the request as either a POST HTTP method with a JSON body, or a GET HTTP method with a query string.

V2 only allows you to use the GET HTTP method with a query string.
 

Request time formats

The premium version of this endpoint uses the following date/time format in both the pagination parameters and the timePeriod response field: YYYYMMDDHHmm

The v2 endpoint uses ISO 8601/RFC 3339 date/time format in both the pagination parameters and the start and end response fields: YYYY-MM-DDTHH:mm:ssZ
 

Request parameters

The following is a table of the request parameters for premium and Twitter API v2:

Filtering operators

While the operators between premium and Twitter API v2 are mostly the same, there are some differences in operator availability and some new operators that were introduced to just the Twitter APi v2 version.
