# Adding Actions
Inside the "ACTIONS" block on the canvas, click the **"Add action"** button.
An **"Add Action" sidebar** will pop up listing all available actions. These are typically categorized into:
* **UserFlux Actions:** Core actions provided by the platform.
* **Available From \[Service Name]:** Actions related to integrated third-party services (e.g., Slack, Mailgun, SendGrid, Postmark).
## **UserFlux Actions**
These are native actions within the platform.
## **Send Email:**
1. Select **"Send Email"** from the "UserFlux Actions" list.
2. In the "Send email" modal:
* Enter the **Subject** for the email.
* Select an **Email Template** from the dropdown. If there are no templates available you will need to use the email template builder in the content tab to create one.
* Choose the **Email Provider** from the dropdown.
3. Click **"Done"**. The "Send email" action will appear in the "ACTIONS" block.
## Using Liquid Variables for Dynamic Content
\
To personalize your emails, you can use Liquid variables in the **Subject** field and within the content of your selected **Email Template**.
Liquid variables are placeholders that get replaced with actual data when the email is sent. They are typically enclosed in double curly braces: `{{ }}`.
\
In order for the liquid variables to be applied you must pass them from the trigger so the email has the relevant data in the payload.
\
See below example from an api trigger where the variables for the subject and email templates are passed to the send email action.
## **Call Webhook:**
1. Select **"Call Webhook"** from the list.
2. In the "Untitled Action" (webhook configuration) modal:
* *(Optional)* Click the pencil icon next to "Untitled Action" to give it a descriptive name.
* Enter the **Endpoint** URL.
* Select the HTTP **Method** (e.g., POST, GET).
* *(Optional)* Click **"+ Add header"** to include custom HTTP headers.
* Enter the **Request Body**, typically in JSON format. The editor may provide suggestions for dynamic variables (e.g., `{{ user.properties }}`, `{{ event.properties }}`, Liquid filters like `| capitalize`, `| json`).
3. Click **"Save"**. The configured webhook action will appear on the canvas. *Note: An "Input incorrect" error may appear if required fields like Endpoint are missing or invalid.*
## **Update User:**
1. Select **"Update User"** from the list.
2. In the "Profile Update Action" modal:
* Select the **user attribute** you want to update from the dropdown.
* The "Set value to" field is typically pre-selected.
* Enter the new **text value** for the attribute.
3. Click **"Done"**.
## **Track User Event:**
1. Select **"Track User Event"** from the list.
2. In the "Track User Event Action" modal:
* Enter the **Event name**.
* Provide any **Event properties** as a JSON object in the text area.
3. Click **"Done"**.
## **Create Dynamic Variable:**
1. Select **"Create Dynamic Variable"** from the list.
2. In the "Create a dynamic variable" modal:
* Enter a **Variable Name**.
* Select the **Type** of variable:
* **User Event Value:** To derive the variable from a property of a recent user event. Configure the event name and property.
* **Liquid Template Value:** To define the variable using Liquid templating language. Enter your Liquid template.
3. Click **"Done"**. This action is useful for storing values to be used in subsequent steps or messages.
## **Actions from Integrated Services**
These actions interact with third-party platforms you've connected. The configuration modals will be specific to each service.

## Managing Actions on the Canvas
* Each specific action added within an "ACTIONS" block (e.g., "Send email", "Call Webhook") will have a **trash icon** next to it, allowing you to delete that individual action.
* The entire "ACTIONS" block (step container) can be managed using the dropdown in its header, which provides options like "Entry Conditions" (to re-edit), "Duplicate Step", and "Delete Step".
* You can add multiple "ACTIONS" blocks to your workflow to create a sequence of steps.
