# Adding an action to a node

> We use actions to add business decisions to the **flow** or link the process to custom integrations and **plugins**.

For more information about actions, check the following section:

<Card title="Actions" href="../../building-blocks/actions" icon="file" />

### Steps for creating an action

To create an action:

<Steps>
  <Step>
    Open **FLOWX Designer** and from the **Processes** tab select **Definitions**.
  </Step>

  <Step>
    Select your **process**.
  </Step>

  <Step>
    Click the **Edit** **process** button.
  </Step>

  <Step>
    Add a new **node**/ edit an existing one.
  </Step>

  <Step>
    A few **action parameters** will need to be filled in depending on the selected action type.
  </Step>

  <Step>
    Add **an action** to the **task node**, for example **sending a Kafka event** to an integration:
  </Step>
</Steps>

* set **Address** (topic) name
* set message content to be sent
  * `{"test" : ${processInstanceId}, "title": "Test title"}`
* a custom header is always set by default to
  * `{"processInstanceId": ${processInstanceId}}`
* if you want some values to be replaced before sending them to Kafka, they should be marked as such in the action params

<Info>
  The nodes that support actions are [task nodes](../../building-blocks/node/task-node), [user task nodes](../../building-blocks/node/user-task-node), and [send message/receive message tasks](../../building-blocks/node/message-send-received-task-node).
