[Dynamic List node](#dynamic-list-node) 2. [Set Variables node](#set-variables-node) 3. [Wait For Callback node](#wait-for-callback-node) 4. [Integration node](#integration-node) More detail about each new node type is given below. ## Dynamic List node The [Dynamic List node](https://clickatell.gitbook.io/flow/user-facing-nodes/branch-logic-split/menu-nodes-dynamic-list) allows the flow-builder to display a personalized list of options to an end-user. The options shown to end-users in the list are retrieved from the API response.

Under the User-Facing nodes, drag-and-drop the Dynamic List node onto the canvas and configure its details.

## Set Variables node The [Set Variables nod](https://clickatell.gitbook.io/flow/action-nodes/action-nodes-set-variables)e allows the flow-builder to create variables that can be used (and reused) in a given session. You can set multiple variables using the same Set Variables node. These variables will only be available for the duration of the session. This is an Action node and is not displayed to the end-user.

Under the Action nodes, drag-and-drop the Set Variables node onto the canvas and configure its details.

## Wait For Callback node The [Wait For Callback node](https://clickatell.gitbook.io/flow/action-nodes/action-nodes-wait-for-callback) is used to facilitate an asynchronous process external to Chat Flow and continue the flow when a callback is received. This node will block the flow until a callback is received or the session times out. This node has to used with the Set Variables node.

Under the Action nodes, drag-and-drop the Wait For Callback node onto the canvas and configure its details.

## Integration node You can integrate your Chat Flow application with the following 3rd-party apps using the [Integration node](https://clickatell.gitbook.io/flow/integrations/integration-nodes): * Salesforce * Shopify * Zendesk Support * Zendesk Sell Note that these integrations first need to be set up in the Clickatell Portal before they'll be available in Chat Flow.
