Integrate Sinch WhatsApp OTP in Mobile App

Job ID: 39322046

Budget: $10 – $30 USD

I currently have an OTP system via SMS, and I need to transition this to use WhatsApp OTP, specifically through the Sinch service. This integration is for a mobile app that's built on both iOS and Android platforms, using native Swift and Kotlin programming languages.

- Key Requirements:
- Modify the existing SMS OTP system to utilize WhatsApp through Sinch.
- Ensure seamless integration with both iOS and Android versions of the app.
- Maintain the current OTP functionality while transitioning to the new service.

Ideal candidates for this project would be experts in mobile app development with a strong background in native Swift/Kotlin programming, and experience with Sinch OTP services. Prior work with integrating third-party services into mobile apps would be highly beneficial.
