# Open or close a branch to viewers

> <Note>
  Opening a branch with this endpoint requires permission to edit every model in the branch.
  
  Closing a branch only requires permission to edit the branch on one of its member models.
</Note>

Open a branch to Viewers and Restricted Queriers - including embed users - so they see the branch's content instead of production, or close it again. See [Opening a branch to viewers](/content/develop/branch-mode#opening-a-branch-to-viewers) for more information.
