Set the Identity

Setting the identity allows you to authorize the user.

Retrieve the configuration parameters

To connect your Sinch Chat client to your Sinch account, you need to set the following parameters in the MainActivity.kt file:

Parameter	Description
project_id	Get your project ID from your Sinch Dashboard.
client_id	Get your client ID from your Sinch Dashboard.
region	Use either `EU1` for Europe or `US1` for the United States.
config_id	Populate with "" if you do not have this value
token_secret	Optional

Setting the identity

Next, you must actually authorize the user. To do that, call this method as early as possible to authorize the user:

Copy

Copied

fun setIdentity(config: SinchConfig, identity: SinchIdentity, completion: (Result<Unit>) -> Unit)

You can call this method as many times as you want. Depending on your needs, you can place the method in the MainActivity.kt file or another file which will be run early in the application lifecycle.

For example:

Copy

Copied

val currentIdentity = SinchIdentity.SelfSigned({your_user_id}, {signed token})
val currentEnvironment = SinchConfig({client_id}, {project_id}, {config_id}, {region}, {language})

SinchChatSDK.setIdentity(
    currentEnvironment,
    currentIdentityType
) {
  if (it.isSuccess) {
        Toast.makeText(this, "Set Identity success", Toast.LENGTH_LONG).show()
        Log.d(TAG, "Set Identity success")
    } else {
        Toast.makeText(this, "Set Identity failed", Toast.LENGTH_LONG).show()
        Log.d(TAG, "Set Identity failed with message: ${it.exceptionOrNull()?.message}")
    }
}

Generating a signed token

Sinch must recognize your users somehow, and the most secure way to authenticate is with a signed token.

Warning:

It is NOT recommended to sign user_id on mobile app. You should implement this algorithm and serve it from your backend infrastructure via API interface to prevent any kind of attacks.

Write to us if you want to know algorithm how we're signing user_id.

Now you can use SDK functionalities like chat or push. The next step is displaying the chat app.
