+> [!NOTE]

+>

+> * The deprecation process for `TeamsInfo.getMembers` and `TeamsInfo.GetMembersAsync` APIs have started. Initially, they are heavily throttled to five requests per minute and return a maximum of 10K members per team. This results in the full roster not being returned as team size increases.

+> * You must update to version 4.10 or higher of the Bot Framework SDK and switch to the paginated API endpoints, or the `TeamsInfo.GetMemberAsync` single user API. This also applies to your bot even if you are not directly using these APIs, as older SDKs call these APIs during [membersAdded](../bots/how-to/conversations/subscribe-to-conversation-events.md#members-added) events. To view the list of upcoming changes, see [API changes](team-chat-member-api-changes.md#api-changes).
