# Get Babylon Phase-2 registration details

> This operation returns the details of a specific Babylon Phase-2 registration, including registration status, Bitcoin (BTC) and Babylon addresses, staked amount, and error messages (if any).

Please note that registration is an asynchronous process and may take several minutes to complete. It is recommended to call this operation at regular intervals to track the status.

If the registration request fails, please check the error message and resolve the issues before resubmitting the registration request.

For more information, refer to [Babylon's official doc](https://github.com/babylonlabs-io/babylon/tree/main/docs).
