Check device binding

Use the Thales SDK to check the current device binding state for a provisioned token ID.

Call this before you start a transaction flow. The returned state tells you if you must create a binding first.

Android

public void getBindingState(@NonNull MastercardTAFHelper mastercardTAFHelper, @NonNull String tokenID) {
    try {
        BindingState bindingState = mastercardTAFHelper.getBindingState(tokenID);
    } catch (TMGClientException e) {
        // Handle the error
    }
}

iOS

let vProvisionedTokenID = ""
do {
    let state = try visaCTFHelper.bindingState(forVProvisionedTokenID: vProvisionedTokenID)
} catch let error {
    // Handle the error
}

Next steps by binding state

Use the returned value to choose the next call in your flow.

• UNBOUND

  The provisioned token ID has not been bound to this device yet.

  Create the binding between the client and server. See the create device binding.
• BOUND

  The provisioned token ID is already bound to this device.

  Use the provisioned token ID to authenticate the transaction. See the authenticate a transaction.
