Remove Metadata

Remove transaction metadata values by nullifying the value of each particular key. Action 1 Set custom_tx_id in the transaction metadata.

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

Action 2 Set custom_tx_id to null and log the null value for custom_tx_id.

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

  api.transaction.setMetadata('custom_tx_id', null);

  console.log('custom_tx_id', event.transaction?.metadata?.custom_tx_id);
  /* Outputs "custom_tx_id undefined" */
};

Action 3 Logs the null value for custom_tx_id.

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