Custom User Validation

Catalyst offers you the option to validate and authorize end-users to your application using custom functions. This option allows you configure a Catalyst Basic I/O function to contain the logic of the manner you wish to authorize the user with. During user sign up, the credentials of the user will be validated through this Basic I/O function.

Note: To enable Custom User Validation, you must first ensure that Public Signup has been enabled.

Refer the code snippets below a sample Custom User Validation function in Java, Node.js, and Python:

public class MainClass implements ZCFunction { private static final Logger LOGGER = Logger.getLogger(MainClass.class.getName()); @Override public void runner(Context context, BasicIO basicIO) throws Exception { try { ZCProject.initProject(); ZCSignupUserValidationRequest requestDetails = ZCSignupUserService.getSignupValidationRequest(basicIO); if (requestDetails != null) { /Validation logic starts / LOGGER.info(“Inside null check”); ZCSignupUserValidationResponse validationResponse = ZCSignupUserValidationResponse.getInstance(); if (requestDetails.getUserDetails().getEmailId().contains("@notallowedmail")) { validationResponse.setStatus(ZCSignupValidationStatus.FAILURE); // The user has failed authentication } else { validationResponse.setStatus(ZCSignupValidationStatus.SUCCESS); // The actions that occur in the event of a successful authentication can be customized ZCSignupResponseUserDetails respUserDetails = ZCSignupResponseUserDetails.getInstance(); respUserDetails.setFirstName("{customFirstName}"); respUserDetails.setLastName("{customLastname}"); respUserDetails.setRoleIdentifier("{customRoleName}"); respUserDetails.setOrgId("{customOrgId}"); validationResponse.setUserDetails(respUserDetails); } basicIO.write(validationResponse); / Validation logic ends/ } } catch (Exception e) { basicIO.write(e); LOGGER.log(Level.SEVERE, “Exception in MainClass”, e); basicIO.setStatus(500); } } }
