# Step 3. Enable the Transaction plugin

After you enable this plugin, you can modify the JWT configuration object that you generated. The most common changes are covered in [When to Modify a JWT Configuration Object](/dpoa/docs/s3suite94-configuring-jwt-generation-and-validation-1#when-to-modify-a-jwt-configuration-object).

#### Using the Admin Console

1. In the Admin Console, login and, if needed, switch to the desired tenant. Navigate to **Configuration > API Server > Transaction Plugin**.
2. If the **Status** shows **ACTIVE**, this plugin is already active. Otherwise, click the **Activate** icon to activate the plugin. You can view or modify the configuration by clicking the **Modify** button in the **Actions** column. To generate a new configuration, click the **Modify** button and then click the **Generate** button on the next screen.

#### Using nnl-mgmt.sh

Create a file called Main.json containing the lines below. This specifies the class name for the TransactionPlugin. The API Server automatically creates an object of this class. Don't change the class name.

```json
{
   "class":"com.noknok.gateway.plugin.transaction.JWTTransactionManager"
}
```

Use nnl-mgmt.sh's apiserver import command to import Main.json. The example below shows how to do this for a tenant called investment.

```plaintext
./nnl-mgmt.sh apiserver import -tenantid investment -type TransactionPlugin -name Main -file Main.json
```

Use nnl-mgmt.sh's apiserver create command to generate a new configuration for the Transaction plugin. The example below shows how to do this for the investment tenant.

```plaintext
./nnl-mgmt.sh apiserver create -tenantid investment -type TransactionPlugin -name jwt_config -issuer "https://example.com"
```

For details on the apiserver create and apiserver import commands, see [*API Server Configuration Commands*](/dpoa/docs/s3suite94-api-server-configuration-commands-1).
