Check friendships

Last updated：2024-04-10 16:29

Overview

You can call this operation to batch check the friendships between a user and up to 20 users. If you need a higher limit (50 at maximum), please contact the ZEGOCLOUD technical support team.

ZEGOCLOUD allows one-way or two-way check of friendships. In this example, the friendship between users A and B is checked.

One-way check: Only checks whether user B is in the friend list of user A.
Two-way check: Checks whether users A and B are in the friend list of the other.

Below are possible results.
