## Waiting for a response

By choosing the **Send and Wait for a Response** operation, you can send a message and pause the workflow execution until a person confirms the action or provides more information.

### Response Type

You can choose between the following types of waiting and approval actions:

* **Approval**: Users can approve or disapprove from within the message.
* **Free Text**: Users can submit a response with a form.
* **Custom Form**: Users can submit a response with a custom form.

You can customize the waiting and response behavior depending on which response type you choose. You can configure these options in any of the above response types:

* **Limit Wait Time**: Whether the workflow will automatically resume execution after a specified time limit. This can be an interval or a specific wall time.
* **Append n8n Attribution**: Whether to mention in the message that it was sent automatically with n8n (turned on) or not (turned off).

### Approval response customization

When using the Approval response type, you can choose whether to present only an approval button or both approval *and* disapproval buttons.

You can also customize the button labels for the buttons you include.

### Free Text response customization

When using the Free Text response type, you can customize the message button label, the form title and description, and the response button label.

### Custom Form response customization

When using the Custom Form response type, you build a form using the fields and options you want.

You can customize each form element with the settings outlined in the [n8n Form trigger's form elements](/integrations/builtin/core-nodes/n8n-nodes-base.formtrigger.md#form-elements). To add more fields, select the **Add Form Element** button.

You'll also be able to customize the message button label, the form title and description, and the response button label.
