POST
Submit KYB data
For company applications (isCompany: true), submit the KYB answers here instead of Submit KYC data. The application is taken from your bearer token, so there’s no id in the path. Answers are keyed against the same schema, which returns company and beneficial-owner fields for companies. Partial saves are allowed; isComplete says whether the step is finished. Keep polling GET /v1/applications. If beneficial-owner sync reports problems, the data is still saved and the response includes a uboProcessingError.
