title: "Verify User Is Following - Social Actions API"
description: "Confirm whether one Twitter/X user follows another. Low-cost, low-latency check that avoids scraping the full followers list."
source: "https://docs.socialdata.tools/social-actions/verify-user-following/"
---

This endpoint provides a convenient way to check if a user (identified by `source_user_id`) is following another user (identified by `target_user_id`). The endpoint achieves this without scraping the entire followers list, which allows us to deliver a fully accurate result with minimal latency.

GET https://api.socialdata.tools/twitter/user/{source\_user\_id}/following/{target\_user\_id}

## Headers

**Authorization** `string` — required

Authorization Bearer header containing your SocialData API key

Example: Bearer YOUR\_API\_KEY

## Path Parameters

**source\_user\_id** `integer` — required

The numeric ID of the follower user

Example: 1729591119699124560

**target\_user\_id** `integer` — required

The numeric ID of the user being followed

Example: 1729591119699124560

> **Caution**
> 
> When using languages where the `user_id` value exceeds the default Integer type limit (e.g., JavaScript), you should store `user_id` as a String. Use the `id_str` property returned by the API for these values
