## [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#removed-methods-and-changes-in-method-names)  Removed Methods and Changes in Method Names

All Neynar API v1-related methods have been removed from SDK v2. This version of the SDK will only support Neynar API v2.

### [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#removed-methods)  Removed Methods

The following methods have been removed entirely from SDK v2:

| **Removed Method** | **Replacement** |
| --- | --- |
| `fetchRecentUsers` | Use [webhook](https://docs.neynar.com/docs/how-to-setup-webhooks-from-the-dashboard) or [kafka](https://docs.neynar.com/docs/from-kafka-stream) |
| `fetchAllCastsLikedByUser` | [`fetchUserReactions`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchuserreactions) |
| `lookupUserByFid` | [`fetchBulkUsers`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchbulkusers) |

| `lookUpCastByHash` | [`lookUpCastByHashOrWarpcastUrl`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#lookupcastbyhashorwarpcasturl) |
| `fetchAllCastsInThread` | [`lookupCastConversation`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#lookupcastconversation) |
| `fetchAllCastsCreatedByUser` | [`fetchCastsForUser`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchcastsforuser) |
| `fetchRecentCasts` | Use [webhook](https://docs.neynar.com/docs/how-to-setup-webhooks-from-the-dashboard) or [kafka](https://docs.neynar.com/docs/from-kafka-stream) |
| `fetchUserVerifications` | [`fetchBulkUsers`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchbulkusers) |
| `lookupUserByVerification` | [`fetchBulkUsersByEthOrSolAddress`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchbulkusersbyethereumaddress) |
| `fetchMentionAndReplyNotifications` | [`fetchAllNotifications`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchallnotifications) |
| `fetchUserLikesAndRecasts` | [`fetchUserReactions`](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#fetchuserreactions) |

Checkout [Affected v1 API Methods](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#affected-v1-api-methods) on how to replace it.

### [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#renamed-methods)  Renamed Methods

Several methods in SDK v2 have been renamed for consistency and clarity:

| v1 Method Name | v2 Method Name |
| --- | --- |
| `lookUpCastByHashOrWarpcastUrl` | `lookupCastByHashOrWarpcastUrl` |
| `publishReactionToCast` | `publishReaction` |
| `deleteReactionFromCast` | `deleteReaction` |
| `fetchReactionsForCast` | `fetchCastReactions` |
| `fetchBulkUsersByEthereumAddress` | `fetchBulkUsersByEthOrSolAddress` |

#### [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#methods-updated-to-v2-api)  Methods Updated to v2 API

These methods retain the original method names but now use the v2 version of the neynar API:

| v1 Method Name | v2 Method Name |
| --- | --- |
| `fetchUserFollowersV2` | `fetchUserFollowers` |
| `fetchUserFollowingV2` | `fetchUserFollowing` |
| `lookupUserByUsernameV2` | `lookupUserByUsername` |

## [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#enum-changes)  Enum Changes

### [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#renamed-enums)  Renamed enums

The following enums have been renamed in SDK v2 to align with the updated naming conventions:

| v1 Enum Name | v2 Enum Name |
| --- | --- |
| `TimeWindow` | `FetchTrendingChannelsTimeWindowEnum` |
| `TrendingFeedTimeWindow` | `FetchTrendingFeedTimeWindowEnum` |
| `BulkCastsSortType` | `FetchBulkCastsSortTypeEnum` |
| `BulkUserAddressTypes` | `BulkUserAddressType` |

### [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#enum-key-changes)  Enum Key Changes

Certain enum keys have been modified in SDK v2. If you were using the following enums, be aware that their key formats may have changed:

- `NotificationType`
- `ValidateFrameAggregateWindow`
- `FetchTrendingChannelsTimeWindowEnum` (formerly `TimeWindow`)
- `FetchTrendingFeedTimeWindowEnum` (formerly `TrendingFeedTimeWindow`)
- `FetchBulkCastsSortTypeEnum` (formerly `BulkCastsSortType`)
- `BulkUserAddressType` (formerly `BulkUserAddressTypes`)

## [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#import-path-changes)  Import Path Changes

All the api-related enums and schemas are now centralized and exported from `/build/api` directory instead of `/build/neynar-api/v2/*`

Typescript

```
import {CastParamType, NotificationTypeEnum, User, Cast, ...etc } from '@neynar/nodejs-sdk/build/api'
```

Imports for following `isApiErrorResponse` utility function and Webhook interfaces remains the same

Typescript

```
import { isApiErrorResponse, WebhookFollowCreated, WebhookFollowDeleted, WebhookReactionCreated, WebhookReactionDeleted, WebhookCastCreated, WebhookUserCreated, WebhookUserUpdated } form '@neynar/nodejs-sdk'
```

## [​](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide\#affected-v1-api-methods)  Affected v1 API Methods

The following methods have been completely removed in SDK v2 (Ref. [Removed Methods](https://docs.neynar.com/reference/neynar-nodejs-sdk-v1-to-v2-migration-guide#removed-methods)). As a result, the response structure will be different in the new methods that replace the deprecated v1 methods.
