# Connecting entities

When creating a connection, if you specify the collection of the entity being connected to, you can create the connection using the value of its 'name' property or its UUID.

## Request syntax

To create a connection, the entity being connected to can either be specified by just its UUID, or both its collection and the value of its 'name' property.

Connect by UUID

    curl -X POST https://api.usergrid.com/<org>/<app>/<connecting_collection>/<connecting_entity>/<relationship>/<connected_entity>
    
Connect by 'name' property

    curl -X POST https://api.usergrid.com/<org>/<app>/<connecting_collection>/<connecting_entity>/<relationship>/<connected_collection>/<connected_entity>

Parameters

Parameter	            Description
---------               -----------
org	                    Organization UUID or organization name
app	                    Application UUID or application name
connecting_collection	Name or UUID of the collection of the connecting entity.
connecting_entity	    Name or UUID of the connecting entity. 
relationship	        Type of connection being created (e.g., likes)
connected_collection	Name or UUID of the collection of the entity being connected to. 
connected_entity	    Name or UUID of the entity being connected to.

If the connecting entity is a 'user' entity, the 'username' should be used rather than the 'name'.

'connected_collection' is not required if the entity being connected to is specified by its UUID.
