+### Send data to downstream destinations
+
+When a journey instance reaches a **Send to Destination** step, you can configure how data is sent to your desired destination. This step allows you to define where the data goes, what actions are performed, and how information is mapped, giving you control over the integration. Event-Triggered Journeys currently supports all [Actions Destinations](docs/connections/destinations/actions/).
+
+For other destinations or more complex logic, you can use [Destination Functions](/docs/connections/functions/destination-functions/).
+
+#### Configure the Destination Send Step
+
+1. **Select a Destination**  
+   Choose the destination where you want to send data. Currently, only [Actions Destinations](docs/connections/destinations/actions/) and [Destination Functions](/docs/connections/functions/destination-functions/) are supported.
+
+2. **Choose an Action**  
+   Specify the action to take within the selected destination. For example, you might update a user profile, trigger an email, or log an event.
+
+3. **Define the Event Name**  
+    Add a descriptive event name to send to your destination.
+
+4. **Define the Payload Attributes**  
+   - The **journey context** provides a set of attributes from the entry event or events used in the Hold Until operator that can be included in the payload.
+   - You may also add a user's profile traits to the destination payload.
+   - Review the available attributes and decide which ones to include in your data send.
+
+5. **Map Attributes to Destination Keys**  
+   - Use the mapping interface to link payload attributes to the appropriate keys required by the destination.  
+   - For example, map `user_email` from the journey context to the `email` field expected by the destination.
+
+6. **Test the Integration**  
+   - Send a **test event** to validate the configuration.  
+   - Ensure that the data is received correctly by the destination and mapped as expected.
+
+When a journey reaches this step, the Segment prepares and sends the payload based on your configuration. The integration ensures compatibility with the selected destination’s API, allowing seamless data transfer and execution of the specified action.

 For example, in an abandonment journey, suppose a user starts two applications (like `application_started`), each with a different `application_id`. By setting `application_id` as the unique identifier, Segment can match follow-up events (like `application_completed`) to the correct application journey. As a result, each journey instance only receives the completion event for its specific application.
 
-#### Send data to downstream destinations

-Event-Triggered Journeys lets you send journey data to supported destinations, facilitating real-time, personalized messaging. Event-Triggered Journeys supports the [Braze (Actions)](/docs/connections/destinations/catalog/actions-braze-cloud/), [Customer.io (Actions)](/docs/connections/destinations/catalog/actions-customerio/), and [Iterable (Actions)](/docs/connections/destinations/catalog/actions-iterable/) destinations.
+### Notes and limitations
 
-For other destinations, you can use [Destination Functions](/docs/connections/functions/destination-functions/) to run additional logic, like enriching with [Profile API traits](/docs/unify/profile-api/) or filtering the payload.
+- **Supported destinations:** Only Actions Destinations in the Segment catalog are supported.  
+- **Data mapping:** Ensure all required keys for the destination are properly mapped to avoid errors.
 
 ## Best practices

 - **Entry event requirements**: The entry event you use must already exist in your Segment workspace for it to appear as a selection in journey setup. Make sure that you've already created the event before setting up your journey.
 - **Event property filters**: You can filter event properties using the `equals` or `equals any of` operators. When you apply multiple conditions, filters operate with `AND` logic, meaning all conditions must be true for the event to trigger entry into the journey.
 - **Audience filtering**: You can only use active, pre-existing audience records as filters. For more complex filtering, like specific profile traits or multiple audiences, first [create the audience](/docs/engage/audiences/#building-an-audience) in **Engage > Audiences**, then apply it as a filter once it’s live.
-- **Destination options**: While Event-Triggered Journeys support several [actions-based destinations](/docs/connections/destinations/actions/) (like Braze, Customer.io, and Iterable) you can only add one destination for each journey instance. For other destinations, use a Destination Function to apply custom logic to the payload.
+- **Destination options**: While Event-Triggered Journeys support all [actions-based destinations](/docs/connections/destinations/actions/) and Destination Functions, you can only add one destination per Send to Destination step. If you need to send to multiple destinations, you can use multiple Send to Destination steps.
 - **Event payload structure**: Each payload sent to a destination includes a unique key to identify the specific send step within the journey, rather than the journey instance itself. You can also set a custom event name to make it easier to identify the specific event instance you want to track in your destination.
 - **Editing and versioning**: After you publish an event-triggered journey, you won't be able to edit it. To modify a journey, create a new journey. 
 - **Real-time delivery**: Event-Triggered Journeys aim for an expected delivery time of under 5 minutes from the moment an event is performed to when the payload reaches the destination, assuming there is no delay step in the journey. However, external factors outside of Segment's control may occasionally introduce latency.
