# Preserve Values on Forms Rendering

> Render Forms using Actions and transaction metadata values would be preserved and available when users continue the authentication flow.

[Render Forms using Actions](/docs/customize/forms/render) and transaction metadata values would be preserved and available when users continue the authentication flow.

To learn more about using Forms with Actions, read [Render Forms using Actions](/docs/customize/forms/render).

**Action 1**

Sets a `custom_tx_id` in the transaction metadata.

```javascript lines theme={null}
exports.onExecutePostLogin = async (event, api) => {
  api.transaction.setMetadata('custom_tx_id', 'xyz123');
};
```

**Action 2**

Renders a Form. Then it logs the preserved `custom_tx_id` when continuing the Actions execution.

```javascript lines theme={null}
exports.onExecutePostLogin = async (event, api) => {
  api.prompt.render(event.secrets.FORM_ID);
};

exports.onContinuePostLogin = async (event, api) => {
  console.log('custon_tx_id', event.transaction?.metadata?.custom_tx_id);
  /* Outputs "custom_tx_id xyz123" */
};
```
