# Card Node

> Learn how to add Card nodes to a workflow, including interactive cards and pinned group cards. Step-by-step examples show how to create and configure cards that send Cool Cards, ideal for scenarios such as ticket alerts and project risk management.

A Card node sends a lightweight interactive card that supports real-time interaction and multi-user collaboration when the workflow reaches this step. Cards come in two types: interactive cards and pinned group cards. Card nodes usually appear in pairs — a Send Card node and an Update Card node. This article explains how to add Card nodes to a workflow.

## What Is a Card Node

Card nodes are one of the hallmarks of an app with Cool App enabled. A YiDA interactive card is a lightweight, real-time, multi-user, data-driven card. It lets the system automatically send interactive cards during a workflow. When a user clicks a button on the card, the card runs various business shortcuts based on the actions configured in advance. It suits common collaboration scenarios such as ticket alerts and project risk management.

## Using Card Nodes

<Note>
  Before you use a Card node in a workflow to send a Cool Card, you must first **publish the app to the custom Cool App center** and enable the Cool App in at least one group. For details, see [Cool App](/yida/cool-app/ub4y1n).
</Note>

This article uses the **Repair Request** form template as an example to explain how to send a Cool Card to a group.

1. Sign in to the YiDA workbench. Select the target app and go to its Page Management page.
2. Click the **+** icon in the upper-left corner, select Create workflow form > Create from template > Repair Request template, and click Use.
3. On the form design page, click Workflow design at the top.
4. Hover over the connecting line between workflow steps. A **+** button appears. Click **+** and select Card node > Send Card node.

<Steps>
  <Step title="Select the Send Card node, then in the right panel select Official templates > Pinned card > Ticket kanban, and click Use" />

  <Step title="Below the selected card, click Open card preview" />

  <Step title="Set Submitter to the workflow Applicant, Product name to Repair subject, and Ticket type to Details" />

  <Step title="Configure the card action to open the App internal page via the Sidebar, with the Repair Request Details page as the target" />

  <Step title="Step 5">
    Set the card Send scope to any group with Cool App enabled, set Group visibility to Visible to all, and set the Pinned card duration to 1 hour.
  </Step>

  <Step title="Set the card send rule so that when the Details value is the same, Update the existing card, and set the DingTalk chat list prompt to Ticket kanban" />

  <Step title="After the Send Card node, add an Assignee node and set the Assignee to Applicant" />
</Steps>

After adding the node, click **Publish workflow**.

11. Access the app and submit a record.
12. Open the configured notification group to check whether the pinned card was sent successfully.

As shown below, the card has been sent successfully.
