The channel identifier will be used when applying for third-party login and cloud-to-cloud connection. If you are an OEM App, please obtain it according to the package name. For example, your App package name is: com.aa.bb, then your channel identifier is: aabb. If your App is developed based on Tuya's SDK, you can find the channel identifier under the SDK application details page on the platform.
If you want to change the channel identifier, you can submit a Technical ticket request on the platform.
