# 7.1 Create Group

Using `createGroup` method a new group is created. The group can be either of type `PUBLIC` or `PRIVATE`, from the enum GroupType in BayunCore. The user creating the group automatically becomes a member of the group, with full authorization for complete group-management functionality for that group. The developer can choose to enforce more fine-grained access controls if desired.

**Method parameters :**

* **groupName**: Group name(Optional)
* **groupType**: Type of group.
* **success**: Success block to be executed after group is successfully created.
* **failure**: Failure block to be executed if group creation fails, returns BayunError.
