## HumanConnect.open argument properties
Before invoking the function `HumanConnect.open(options)` to launch Connect, you can supply the following parameters for the options object argument:
| Attribute | Description |
| clientId | Your application's `clientId`. If you don't have one, please reach out to open a developer account |
| clientUserId | Can be an email address or any UTF-8 string to identify the user |
| token | (**required**) Session token initially retrieved from Human API's authentication service |
| onClose | A Javascript function with this signature: `function close(response){...}` |
| onConnectSource | A Javascript function with this signature: `function (response){...}` |
| onDisconnectSource | A Javascript function with this signature: `function (response){...}` |
## Human Connect session response during user activity
After the user adds or removes data sources and closes Connect, your `onClose` callback will be invoked with a response argument. The response object is as follows:
| Property | Type | Description |
| status | String | Identifies whether the session terminated normally (`SUCCESS`) or abnormally : `SESSION_TOKEN_INVALID`, `SESSION_TOKEN_EXPIRED` or `MISSING_SESSION_TOKEN` |
| sessionResults | Object | Identifies details about the data sources which the user connected or disconnected |
| sessionResults.connectedSources | Array[Object] | Identifies data sources connected by the user during the session. The array can be empty if the user did not connect any source |
| sessionResults.disconnectedSources | Array[Object] | Identifies data sources disconnected by the user during the session. The array can be empty if the user did not disconnect any source |
| currentConnections | Array[Object] | Identifies active data sources for the user, including sources which were connected in previous sessions |
See below for an example response:
Does the response payload look different for onConnectSource and onDisconnectSource?
The main difference lies in the "response.status". When onConnectSource is invoked, "response.status"="CONNECTED_SOURCE". When onDisconnectSource is invoked, "response.status"="DISCONNECTED_SOURCE".
