When setting up an application release to be deployed to a Belden Horizon Data Operations instance, it is possible to pass an API token for the application release's respective Docker container. 

# Before You Begin

Create a Draft Application Release. See [Create a Draft Application Release](docId\:UOv7H2wjtYNeoSd9aiz3c) for details.

# Step 1: Create an `EGDE_API_TOKEN` Variable

For an application release, create a variable named `EDGE_API_TOKEN`.  Configure the remaining parameters and options to your preference.

# Step 2: Complete and Deploy Application Release

See *Step 3-Step 5* in [Add a Draft Application Release](docId\:UOv7H2wjtYNeoSd9aiz3c). 

# Step 3: Verify API Key Token Creation

From Belden Horizon Data Operations, you will verify the creation of the `MPC-APP` token.

1. In Belden Horizon Data Operations, navigate to **System **>** Tokens**.
    
   The *NATS Proxy *pane appears.

# Step 4: Verify Passed API Token to Docker Container

From Belden Horizon Data Operations again, you will verify the API Token was also passed to the Docker Container.

1. In Belden Horizon Data Operations, select **Applications**.
   The *Dashboard *pane appears.
2. Click **Containers**. 
   The *Containers *pane appears.
3. From the deployed application release's respective Docker Container, click **Inspect**.

4. Scroll down till you see **Config**. In the **Env** section, verify that `EDGE_API_TOKEN` contains the same value as `MPC-APP` does in *Step 3: Verify API Token Creation*.
