Share Values with Forms

You can render Forms using Actions and pass transaction metadata values to the Form. Action 1 Sets a custom_tx_id in the transaction metadata.

exports.onExecutePostLogin = async (event, api) => {
  api.transaction.setMetadata('custom_tx_id', 'xyz123');
};

Action 2 Renders a Form passing the custom_tx_id from the transaction metadata as vars parameter. Then it compares the custom_tx_id value at the transaction metadata with the one passed to the Form, when continuing the Actions execution.

exports.onExecutePostLogin = async (event, api) => {
  api.prompt.render(event.secrets.FORM_ID, {
    vars: {
      custom_tx_id: event.transaction?.metadata?.custom_tx_id
    }
  });
};

exports.onContinuePostLogin = async (event, api) => {
  console.log('Does custon_tx_id match?',
    event.prompt?.vars?.custom_tx_id === event.transaction?.metadata?.custom_tx_id
  );
  /* Outputs "Does custon_tx_id match? True" */
};
