Official description

OneUptime is a solution for monitoring and managing online services. The resend-verification-code endpoint allows any authenticated user to trigger a verification code resend for any UserWhatsApp record by ID. Ownership is not validated (unlike the verify endpoint). This affects the UserWhatsAppAPI.ts endpoint and the UserWhatsAppService.ts service.
