Our solution encompasses a secure RESTful API and Android SDK for devices, which not only facilitates clients to implement their own encryption techniques, data transmission methods, and business logic with ease, but also ensures robust security and stringent permission authentication. This comprehensive approach allows for a straightforward integration into their existing systems, providing a secure and controlled access environment. For third-party applications, access to our API is granted through a secure authentication process involving encrypted keys and passwords. Our API also includes advanced permission checks to ensure that only authorized users can access sensitive data. Should you require access to our open API, please reach out to our sales team for further assistance and to discuss your security and access needs.
