# Resource: bitbucketserver_project_branch_permissions

Provides the ability to apply project ref restrictions to enforce branch permissions. A restriction means preventing writes on the specified branch(es) by all except a set of users and/or groups, or preventing specific operations such as branch deletion.

## Example Usage

```hcl
resource "bitbucketserver_project_branch_permissions" "pr_only" {
  project          = "MYPROJ"
  repository       = "repo"
  ref_pattern      = "refs/heads/master"
  type             = "pull-request-only"
}

resource "bitbucketserver_project_branch_permissions" "no_deletes" {
  project     = "MYPROJ"
  repository  = "repo"
  ref_pattern = "heads/**/master"
  type        = "no-deletes"
  exception_users  = ["admin"]
  exception_groups = ["group_1", "group_2"]
}
```
