# 7.7 Add Group Members

The `addInGroup` function is used to add  new members to the Group. The members to be added in the group may belong to different companies, provided that the company and the member must already be registered with Bayun. Any existing member of the group can add a new members. The developer can enforce stricter access-mechanisms on top if desired (e.g. only group-owner or group-admin is allowed to add new members).

The function takes the following parameters :

* **groupId** :  Group Id of the Group.
* **groupMembers** :  `List<GroupMember>` object.&#x20;
* **success** : Success block to be executed after members are added to the group.
* **failure** : Failure block to be executed if members could not be added to the group, returns `BayunError`.
