# Customize the Acumatica Endpoint

Creating a dedicated Web Service Endpoint named `StacksyncDefault` is optional. Use it only when you want to customize the Acumatica objects and fields available in Stacksync instead of using the standard `Default` endpoint.

### Create the endpoint

1. In Acumatica, open **Web Service Endpoints**.
2. Select the latest version of the `Default` endpoint.<br>

3. Review the objects included in that endpoint.<br>

4. Click **Extend Endpoint**.<br>

5. In the dialog, enter:
   * **Endpoint Name:** `StacksyncDefault`
   * **Endpoint Version:** Use the current version or another valid version number<br>

6. Click **OK**.
7. Open the new `StacksyncDefault` endpoint and add, remove, or update the objects and fields required for your sync.<br>

8. Save your changes.

Extending the endpoint creates a separate configuration. It does not modify the original `Default` endpoint.

### Endpoint selection for two-way sync

When using [two-way sync](https://docs.stacksync.com/two-way-sync), Stacksync selects:

1. The latest version of `StacksyncDefault`
2. The latest version of `Default` when `StacksyncDefault` is not available

For example, when these endpoints exist:

* `Default` — `24.200.001`
* `StacksyncDefault` — `23.200.001`
* `StacksyncDefault` — `24.200.001`

Stacksync uses `StacksyncDefault` version `24.200.001`.

Endpoint configuration for [Agentic Workflows](https://docs.stacksync.com/agentic-workflows) is handled separately within each workflow step.
